receiving an informing message sent by a media file server, wherein the informing message is used for informing a media file client that a target media file exists in the media file server;

extracting a currently played data frame from data of a currently played media file according to the notification message, wherein the currently played data frame is a data frame played when the notification message is received;

generating a switching request according to the current playing data frame, wherein the switching request comprises: currently playing the data frame;

and sending a switching request to the media file server so that the media file server can determine the data to be played from the data of the target media file according to the current playing data frame.

Optionally, step 302 may include:

determining a first target data frame which is the same as a current playing data frame in buffer data of data to be played, wherein the buffer data of the data to be played comprises at least one data frame;

Optionally, playing the target media file according to the data to be played includes:

Fig. 4-1 is a flowchart illustrating a method for playing a media file according to yet another exemplary embodiment, which is illustrated in the embodiment of fig. 1 by applying the method for playing the media file. Referring to fig. 4-1, the media file playing method may include the following steps:

in step 401, in the process of playing the media file by the media file client, the media file server detects whether a target media file exists in the media file server, where the target media file is a high-version file of the media file currently played by the media file client.

The media file client may be a video client or an audio client, the video client may be a youth client, an love art client, and the like, the audio client may be a dog music client, a hundred degree music client, and the like, and the media file may be a video file or an audio file, which is not limited in this disclosure.

When playing a media file, a media file client needs to obtain data corresponding to the media file from a server, where the server may be a media file server configured with the media file client, or may also be a third-party server, for example, when the media file client is a cooling client, the server may be a cooling server, or may also be an artistic server (third-party server), which is not limited in this embodiment of the disclosure.

When the media file client acquires the data of the media file from the media file server, the media file server can send the data of the media file to the media file client, and at the moment, the media file server can consider that the media file client plays the media file; or, when the media file client plays the media file, the media file client may send play instruction information to the media file server, and the media file server may determine, according to the play instruction information, that the media file client plays the media file indicated by the play instruction information.

When the media file server determines that the media file client plays the media file, it may detect whether a target media file exists in the media file server, where the target media file is a high-version file of the media file currently played by the media file client. For example, assuming that the currently played media file of the media file client is a video file with a file name "xxx.wmv", the target media file is also a video file with a file version "xxx.wmv", and the file version of the target media file is higher than that of the currently played media file, for example, the definition of the target media file is higher than that of the currently played media file, and the sound quality of the target media file is better than that of the currently played media file.

Optionally, the media file server may determine, according to the data of the media file sent to the media file client, an identifier of the media file currently played by the media file client and a file version of the currently played media file, or the media file client may send, to the media file server, the identifier of the currently played media file and the file version of the currently played media file, which are carried in the play instruction information. The media file server can store the corresponding relation between the media file identification and the file version, inquire the corresponding relation between the media file identification and the file version according to the identification of the currently played media file to obtain the media files of all versions corresponding to the identification of the currently played media file, and then detect whether the target media file exists in the media files of all versions corresponding to the identification of the currently played media file. For example, taking a media file as a video file for illustration, the correspondence between the media file identifier and the file version stored in the media file server may be as shown in table 1 below:

TABLE 1

Assuming that the identifier of the media file currently played by the media file client is ID-a and the file version is a1, the media file server queries the corresponding relationship shown in table 1 according to the identifier ID-a to obtain all versions of the media files corresponding to the identifier ID-a on the media file server, as can be seen from table 1, there are 3 media files corresponding to the identifier ID-a on the media file server, where the 3 media files corresponding to the identifier ID-a are a1 media file, a2 media file and A3 media file, respectively, where the a1 media file is a standard definition file (that is, the definition of the a1 media file belongs to the definition range corresponding to the standard definition), the a2 media file (high definition, the definition of the media file with the file version a2 belongs to the definition range corresponding to high definition), and the media file with the file version A3 is an ultra-high definition file (that is, the definition of the media file with the file version A3 belongs to the definition range corresponding to ultra-high definition), so that it can be determined that the file version a2 is higher than the file version a1, the file version A3 is higher than the file version a2, and the media file server can determine the target media file among the 3 media files corresponding to the identifier ID-a, for example, because the file version a2 and the file version A3 are both higher than the file version a1, the media file server determines that the target media file is the media file with the file version a2 and the media file with the file version A3.

It should be noted that, regarding the description of the media file identifier ID-B and the file version corresponding to the media file identifier ID-B, and the description of the media file identifier ID-C and the file version corresponding to the media file identifier ID-C in table 1, reference may be made to the description of the media file identifier ID-a and the file version corresponding to the media file identifier ID-a, which is not described herein again in this disclosure.

It should be further noted that, in the embodiment of the present disclosure, the data of the currently played media file may be obtained by the media file client from a media file server configured with the media file client, or obtained by the media file client from a third-party server. If the data of the currently played media file is acquired by the media file client from the media file server matched with the media file client, the media file server can periodically detect whether a target media file exists in the media file server in the process of playing the media file by the media file client, if the data media file client of the currently played media file is acquired from a third-party server, the media file client can send a detection request to the media file server matched with the media file client, the detection request can carry an identifier of the currently played media file by the media file client, and the media file server matched with the media file client can detect whether the target media file exists in the media file server according to the identifier of the carried media file in the detection request when receiving the detection request, the embodiments of the present disclosure do not limit this.

In step 402, when the target media file exists in the media file server, the media file server determines the data to be played in the target media file according to the currently played data frame of the currently played media file.

If the media file server detects that the target media file exists in the media file server in step 401, the media file server determines the data to be played in the target media file according to the currently played data frame of the media file currently played by the media file client.

For example, referring to fig. 4-2, it shows a flowchart of a method for determining data to be played in data of a target media file by a media file server according to the embodiment shown in fig. 4-1, and referring to fig. 4-2, the method may include the following steps:

in sub-step 402A, the media file server counts the number of target media files.

The media file server may count the number of detected target media files, illustratively, the media file server counts the number of detected target media files identified as ID-a. As can be seen from the above step 201, the media file server determines that the target media file is a media file with a file version A2 and a media file with a file version A3. Therefore, the number of target media files counted by the media file server is 2.

In sub-step 402B, when the number of the target media files is greater than or equal to 2, the media file server determines the data to be played from the target media file with the highest version according to the currently played data frame of the currently played media file.

When the media file server determines in sub-step 402A that the number of target media files is greater than or equal to 2, the media file server determines the data to be played from the target media file with the highest version according to the currently played data frame of the currently played media file, for example, because the file version A3 is higher than the file version a2, the media file server determines the data to be played from the target media file with the file version A3 according to the currently played data frame of the currently played media file.

Optionally, in this step 402B, the media file server may first sort the file versions of the media files, then determine the target media file with the highest file version according to the sorting result, and then determine the data to be played from the target media file with the highest version according to the currently played data frame of the currently played media file.

For example, referring to fig. 4-3, it shows a flowchart of a method for determining data to be played in a target media file by a media file server according to the embodiment shown in fig. 4-1, and referring to fig. 4-3, the method may include the following steps:

in sub-step 4021, the media file server sends a notification message to the media file client, the notification message being used to notify the media file client that the target media file exists in the media file server.

When the media file server detects that the target media file exists in the media file server, the media file server may send a notification message to the media file client, where the notification message is used to notify the media file client that the target media file exists in the media file server. In practical application, the notification message may be a character string that can be recognized by both the media file server and the media file client, and the embodiment of the present disclosure does not limit this.

In sub-step 4022, the media file client receives the announcement message sent by the media file server.

When the media file server sends a notification message to the media file client, the media file client may receive the notification message. Wherein the notification message is used to notify the media file client that the target media file exists in the media file server.

In sub-step 4023, the media file client extracts the currently played data frame from the data of the currently played media file according to the notification message, where the currently played data frame is the data frame played when the notification message is received.

When the media file client receives the notification message sent by the media file server, the media file client may extract a currently played data frame from the data of the currently played media file of the media file client according to the notification message, where the currently played data frame may be a data frame being played when the media file client receives the notification message. For example, assuming that the data frame being played by the media file client when the notification message is received is 1120354 th data frame in the currently played media file, where the 1120354 th data frame may be a data frame W, the current data frame extracted by the media file client is the data frame W. In practical applications, when the currently played media file of the media file client is a video file, the currently played data frame may be a frame of image, for example, 1120354 th frame of image.

In sub-step 4024, the media file client generates a switch request according to the currently played data frame, where the switch request includes: the data frame is currently played.

After extracting the currently played data frame, the media file client may generate a switching request including the currently played data frame according to the currently played data frame. Illustratively, the media file client generates a switch request comprising a data frame W. Optionally, the switching request may further include a first play time corresponding to the currently played data frame in the media file currently played by the media file client, where the first play time may be 1:28:30(1 hour 28 minutes 30 seconds), and this is not limited in this embodiment of the disclosure.

In sub-step 4025, the media file client sends a switch request to the media file server.

After generating the switching request including the currently played data frame, the media file client may send the switching request including the currently played data frame to the media file server. The media file server can determine the data to be played from the data of the target media file according to the currently played data frame.

In sub-step 4026, the media file server receives a switch request sent by the media file client.

When the media file client sends a switching request to the media file server, the media file server may receive the switching request sent by the media file client, where the switching request may include: and the media file client extracts the currently played data frame from the data of the currently played media file when receiving the notification message. Illustratively, the media file server receives a switch request including a data frame W sent by the media file client.

In sub-step 4027, the media file server determines a first target data frame in the data of the target media file that is the same as the currently playing data frame.

After receiving a switching request sent by a media file client, a media file server can analyze the switching request to obtain a current playing data frame, and then determines a first target data frame which is the same as the current playing data frame in data of a target media file.

Referring to fig. 4-4, which is a flowchart illustrating a method for determining a first target data frame in data of a target media file by a media file server according to the embodiment shown in fig. 4-1, referring to fig. 4-4, the method may include the following steps:

in sub-step 40271a, the media file server determines a first play time corresponding to the currently playing data frame in the currently playing media file.

The media file server may store information of a currently played media file, and the information of the currently played media file may include: the corresponding relation between the data frame and the playing time records the data frame in the media file currently played by the media file client and the playing time corresponding to the data frame in the currently played media file. The media file server can obtain a first playing time corresponding to the currently played data frame in the currently played media file according to the corresponding relation between the currently played data frame query data frame and the playing time. For example, the media file server queries a corresponding relationship between a data frame W (currently playing data frame) and a playing time to obtain a first playing time corresponding to the data frame W in the currently playing media file, where the first playing time may be 1:28: 30.

In sub-step 40272a, the media file server compares the currently playing data frames in turn with data in a preset time period including the first playing time in the target media file.

After the media file server determines a first playing time corresponding to the currently played data frame in the currently played media file, the currently played data frame may be sequentially compared with data in a preset time period including the first playing time in the target media file. The preset time period may be set according to actual needs, and is not limited in the embodiment of the present disclosure, for example, the preset time period may be 5 minutes, the preset time period including the first play time may be 1:26:30 to 1:31:30, and the media file server compares the data frames W with the data in the target media file in the time period of 1:26:30 to 1:31:30 in sequence.

For example, please refer to fig. 4-5, which shows a flowchart of a method for comparing, by a media file server, a currently played data frame with data in a preset time period including a first play time in a target media file in sequence according to the embodiment shown in fig. 4-1, and referring to fig. 4-5, the method may include the following steps:

in sub-step 40272a1, the media file server divides data in a preset time period including the first play time in the target media file into at least two data segments.

The media file server may divide data in a preset time period including the first play time in the target media file into at least two data segments, where the media file server may divide the data in the preset time period including the first play time at equal intervals, or may divide the data in the preset time period including the first play time according to a correlation between data frames in the data in the preset time period including the first play time in the target media file, and this is not limited in the embodiments of the present disclosure. For example, the data within the preset time period including the first play time may include a plurality of data frames, and the media file server may calculate a similarity between the plurality of data frames, regard the similarity between the plurality of data frames as a correlation between the plurality of data frames, and then divide the data within the preset time period including the first play time according to the correlation.

For example, the preset time period including the first playing time may be 1:26:30 to 1:31:30, and the data in the preset time period including the first playing time may be K₁K₂K₃K₄W₂WW₇P₄P₂P₀V₀V₉The data in the preset time period including the first playing time comprises a data frame K₁Data frame K₂Data frame K₃Data frame K₄Data frame W₂Data frame W, data frame W₇Data frame P₄Data frame P₂Data frame P₀Data frame V₀And a data frame V₉。

Assuming that the playing time length of each data frame is equal, if the data frame is divided into 4 data segments at equal intervals, the 4 data segments are respectively data segments K₁K₂K₃Data segment K₄W₂W, data segment W₇P₄P₂And a data segment P₀V₀V₉Each data segment includes 3 data frames.

If the data frames are divided according to the relevance between the data frames in the data in the preset time period including the first playing time in the target media file, the media file server can calculate the data frame K₁Data frame K₂Data frame K₃Data frame K₄Data frame W₂Data frame W, data frame W₇Data frame P₄Data frame P₂Data frame P₀Data frame V₀And a data frame V₉The data frames with the correlation degree larger than the preset threshold value and adjacent data frames are divided into a group, for example, the data frame K₁And a data frame K₂The correlation degree is larger than a preset threshold value, and the data frame K₂And a data frame K₃The correlation degree is larger than a preset threshold value, and the data frame K₃And a data frame K₄The correlation degree is larger than a preset threshold value, and the data frame K₄And a data frame W₂If the correlation degree is less than the preset threshold value, the media file server will transmit the data frame K₁Data frame K₂Data frame K₃And a data frame K₄Divided into one group, and similarly known, the data frame W₂Data frame W and data frame W₇As a group, data frame P₄Data frame P₂And a data frame P₀As a group, data frame V₀And a data frame V₉The divided data segments may include 4 data segments, and the 4 data segments are data segments K respectively₁K₂K₃K₄Data segment W₂WW₇Data segment P₄P₂P₀And a data section V₀V₉。

In sub-step 40272a2, the media file server extracts at least one characteristic data frame in each data segment, where each characteristic data frame is used to characterize the attribute of the playing content corresponding to the data segment where each characteristic data frame is located.

After dividing the data in the preset time period including the first play time in the target media file into at least two data segments, the media file server may extract at least one feature data frame in each data segment, where each feature data frame is used to represent an attribute of the play content corresponding to the data segment in which each feature data frame is located. The media file server can calculate the characteristic value of each data frame in each data segment, then determine the characteristic data frame according to the characteristic value of each data frame, and extract the characteristic data frame. The detailed implementation process of determining the characteristic data frame by the media file server may refer to related technologies, and details of the embodiment of the present disclosure are not repeated herein.

Illustratively, at least two data segments are taken as the data segment K₁K₂K₃K₄Data segment W₂WW₇Data segment P₄P₂P₀And a data section V₀V₉And assuming that the media file server extracts one characteristic data frame from each data segment, the characteristic data frame extracted by the media file server may be: characteristic data frame K₂A characteristic data frame W and a characteristic data frame P₀And a feature data frame V₉。

In sub-step 40272a3, the media file server compares the currently playing data frame with at least one characteristic data frame in turn.

After the media file server extracts the characteristic data frames, the currently played data frames may be sequentially compared with at least one characteristic data frame, for example, the media file server may compare the currently played data frames with at least one characteristic data frameThe data frame W is sequentially connected with the characteristic data frame K₂A characteristic data frame W and a characteristic data frame P₀And a feature data frame V₉A comparison is made.

In sub-step 40273a, the media file server extracts a first target data frame that is the same as the currently playing data frame from data within a preset time period including the first play time.

After comparing the current playing data frame with the data in the target media file within the preset time period including the first playing time in sequence, the media file server may determine the first target data frame, which is the same as the current playing data frame, in the data in the preset time period including the first playing time, and the media file server may extract the first target data frame. For example, as can be seen from the step 40272a, if a first target data frame in the data within the preset time period including the first play time, which is the same as the currently played data frame, is a characteristic data frame W, the media file server extracts the characteristic data frame W.

Optionally, in this embodiment of the present disclosure, the handover request may further include: and a first playing time corresponding to the currently played data frame in the currently played media file of the media file client. When the switching request further includes a first play time corresponding to the currently played data frame in the media file currently played by the media file client, the media file server may determine the first target data frame according to the method shown in fig. 4 to 6.

Referring to fig. 4-6, which illustrate a flow chart of another method for determining a first target data frame in data of a target media file by a media file server according to the embodiment shown in fig. 4-1, referring to fig. 4-6, the flow chart of the method may include the following steps:

in sub-step 40271b, the media file server compares the currently played data frames with the data in the target media file in sequence within a preset time period including the first play time according to the switching request.

The media file server can analyze the switching request to obtain a current playing data frame in a media file currently played by the media file client and a first playing time corresponding to the current playing data frame. And then, sequentially comparing the current playing data frame with data in a preset time period including the first playing time in the target media file. The process of the media file server sequentially comparing the currently played data frame with the data in the target media file within the preset time period including the first playing time may refer to sub-step 40272a in the embodiment shown in fig. 4-4 and the corresponding embodiment shown in fig. 4-5, which is not described herein again in this embodiment of the disclosure.

In sub-step 40272b, the media file server extracts a first target data frame that is the same as the currently playing data frame from data within a preset time period including the first play time.

The sub-step 40272b may be implemented by referring to the sub-step 40273a in the embodiment shown in fig. 4 to 4, and the embodiments of the present disclosure are not described herein again.

Referring to fig. 4-7, which illustrate a flowchart of a method for determining a first target data frame in data of a target media file by a media file server according to another embodiment shown in fig. 4-1, the method may include the following steps, referring to fig. 4-7:

in sub-step 40271c, the media file server compares the currently playing data frame with the data in the target media file in turn, including the respective playing time.

In an example, it is assumed that the target media file includes data of each playing time, that is, all data of the target media file, that is, the media file server compares the currently played data frame with all data of the target media file in sequence₂D₀D₆......K₁K₂K₃K₄W₂WW₇P₄P₂P₀V₀V₉M₁M₂M₃......MCK₃..., the media file server sequentially connects the currently playing data frame W with the data₂D₀D₆......K₁K₂K₃K₄W₂WW₇P₄P₂P₀V₀V₉M₁M₂M₃......MCK₃...

In sub-step 40272c, the media file server extracts a first target data frame of the data of the target media file that is the same as the currently playing data frame.

After comparing the currently played data frame with the data of each playing time in the target media file in sequence, the media file server may determine a first target data frame, which is the same as the currently played data frame, in the data of each playing time, and the media file server may extract the first target data frame. Referring to step 40271c, if the first target data frame in the data at each playing time that is the same as the currently playing data frame is a data frame W, the media file server extracts the data frame W.

In sub-step 4028, the media file server determines a corresponding first target play time for the first target data frame in the target media file.

The media file server may store information of a target media file, which may include: and the corresponding relation between the data frame and the playing time records the data frame in the target media file and the playing time corresponding to the data frame in the target media file. The media file server may obtain a first target play time of the first target data frame in the target media file according to the first target data frame query data frame and play time correspondence. For example, the media file server queries a corresponding relationship between the data frame and the playing time according to the first target data frame W to obtain a first target playing time corresponding to the first target data frame W in the target media file, where the first target playing time may be 1:30:30(1 hour 30 minutes 30 seconds).

In sub-step 4029, the media file server determines second target data to be played after the first target play time from the data of the target media file.

For example, the media file server determines the data played after 1:30:30 from the data of the target media file, and the data played after 1:30:30 may be the second target data. The media file server may query, according to each time after the first target playing time, a corresponding relationship between a data frame in information of a target media file stored by the media file server and the playing time to obtain the data frame played at each time after the first target playing time, and obtain the second target data according to the data frames played at a plurality of times. For example, assume that the data played after 1:30:30 is W₇P₄P₂P₀V₀V₉M₁M₂M₃......MCK₃.., the media file server may query the corresponding relationship between the data frame in the information of the target media file and the playing time to obtain the second target data W₇P₄P₂P₀V₀V₉M₁M₂M₃......MCK₃..., which are not intended to be limiting by the embodiments of the present disclosure.

In sub-step 4030, the media file server takes the first target data frame and the second target data as data to be played.

After determining the first target data frame and the second target data, the media file server may use the first target data frame and the second target data as data to be played, for example, the media file server uses the first target data frame W and the second target data W₇P₄P₂P₀V₀V₉M₁M₂M₃......MCK₃.... as data to be played,the data to be played may be the WW₇P₄P₂P₀V₀V₉M₁M₂M₃......MCK₃......。

In step 403, the media file server sends the data to be played in the target media file to the media file client.

After determining the data to be played in the target media file, the media file server may send the data to be played in the target media file to the media file client, so that the media file client plays the target media file according to the data to be played in the target media file. It should be noted that, in the embodiment of the present disclosure, the media file server may send the data to be played to the media file client while determining the data to be played in the target media file, which is not limited in the embodiment of the present disclosure. Illustratively, the media File Server determines the WW₇P₄Sending WW to media file client₇P₄And determining P₂P₀V₀Waiting for the data to be played.

In step 404, the media file client receives the data to be played in the target media file sent by the media file server.

When the media file server sends the data to be played in the target media file to the media file client, the media file client can receive the data to be played in the target media file sent by the media file server.

In step 405, the media file client plays the target media file according to the data to be played.

After receiving the data to be played in the target media file, the media file client can play the target media file according to the data to be played in the target media file.

For example, referring to fig. 4-8, it shows a flowchart of a method for a media file client to play a target media file according to data to be played, according to the embodiment shown in fig. 4-1, and referring to fig. 4-8, the method may include the following steps:

in sub-step 4051, the media file client determines whether the buffering progress of the data to be played is greater than the playing progress of the currently played media file since the notification message was received.

It should be noted that, in the embodiment of the present disclosure, during the process of extracting the currently played data frame, generating the switching request, sending the switching request to the media file server, and determining the data to be played in the data of the target media file by the media file server, the media file client is still playing the currently played media file, that is, before the media file client plays the target media file, the media file client is always playing the currently played media file. Therefore, in order to make the target media file and the currently played media file achieve seamless connection switching and achieve the effect of making the user not perceive the switching process, the media file client can judge whether the buffering progress of the data to be played is greater than the playing progress of the currently played media file from the time of receiving the notification message, and when the buffering progress of the data to be played is greater than the playing progress of the currently played media file from the time of receiving the notification message, the media file client plays the target media file according to the data to be played.

For example, please refer to fig. 4-9, which show a flowchart of a method for a media file client to determine whether a buffering progress of data to be played is greater than a playing progress of a currently played media file from when an announcement message is received according to the embodiment shown in fig. 4-1, and referring to fig. 4-9, the method may include the following steps:

in sub-step 40511, the media file client determines a first playing time corresponding to the currently playing data frame in the currently playing media file.

The media file client may store information of played data in a currently played media file, where the information of played data in the currently played media file may include: the corresponding relation between the played data frame and the playing time records the played data frame in the played data in the media file currently played by the media file client and the playing time of the played data frame. The media file client can query the corresponding relation between the played data frame and the playing time according to the currently played data frame to obtain a first playing time corresponding to the currently played data frame in the currently played media file. For example, the media file client queries a corresponding relationship between a played data frame and a playing time according to the currently played data frame W to obtain a first playing time corresponding to the currently played data frame W in the currently played media file, where the first playing time may be 1:28: 30.

In sub-step 40512, the media file client determines the current playing time according to the playing progress of the currently played media file.

The playing progress is the playing time, so the media file client can use the playing progress of the currently played media file as the current playing time. For example, the playing progress of the currently playing media file may be 1:29:00(1 hour, 29 minutes, 0 seconds), and thus the current playing time may be 1:29: 00.

In sub-step 40513, the media file client determines a first target data frame that is the same as the currently played data frame in the buffered data of the data to be played, where the buffered data of the data to be played includes at least one data frame.

The media file server may send the data to be played to the media file client while determining the data to be played, and after receiving the data to be played, the media file client may store the data to be played in a cache space of the terminal, where the data to be played stored in the cache space is buffer data of the data to be played, and the buffer data of the data to be played may include at least one data frame. The media file client may determine, in the buffer data of the data to be played, a first target data frame that is the same as the currently played data frame.

Illustratively, the data to be played may be the WW₇P₄P₂P₀V₀V₉M₁M₂M₃......MCK₃.., the buffer data of the data to be played can be WW₇P₄P₂P₀V₀V₉M₁M₂The buffer data of the data to be played comprises a data frame W and a data frame W₇Data frame P₄Data frame P₂Data frame P₀Data frame V₀Data frame V₉Data frame M₁And a data frame M₂For a total of 9 data frames. As can be seen from the foregoing sub-step 4023, the currently played data frame is W, and therefore, the media file client may compare the currently played data frame W with the data frames in the buffer data of the data to be played in sequence, and determine the first target data frame W that is the same as the currently played data frame.

In sub-step 40514, the media file client determines a corresponding first target play time of the first target data frame in the target media file.

The data to be played sent by the media file server to the media file client may include information of the data to be played, the media file client may store information of buffer data of the data to be played of the target media file, and the information of the buffer data of the data to be played of the target media file may include: and the corresponding relation between the buffer data frame and the playing time records the buffer data frame in the buffer data of the data to be played of the target media file and the playing time of the buffer data frame. The media file client can obtain a first target playing time of the first target data frame corresponding to the target media file according to the corresponding relation between the first target data frame and the playing time. For example, the media file client queries a corresponding relationship between the buffered data frame and the playing time according to the first target data frame W to obtain a first target playing time corresponding to the first target data frame W in the target media file, where the first target playing time may be 1:30: 30.

In sub-step 40515, the media file client determines a second target play time corresponding to the last data frame to be played in the buffered data of the data to be played in the target media file.

The media file client may query the corresponding relationship between the buffered data frame and the playing time according to the last data frame to be played in the buffered data of the data to be played, and obtain a second target playing time corresponding to the last data frame to be played in the buffered data of the data to be played in the target media file. For example, the buffer data of the data to be played may be WW₇P₄P₂P₀V₀V₉M₁M₂If the last data frame to be played in the buffer data of the data to be played is the data frame M₂The media file client can play the data frame M according to the last data frame to be played in the buffer data of the data to be played₂Inquiring the corresponding relation between the buffer data frame and the playing time to obtain the last data frame M to be played in the buffer data of the data to be played₂And at a corresponding second target playing time in the target media file, the second target playing time may be 1:31: 10.

In sub-step 40516, the media file client calculates a play time difference between the current play time and the first play time.

After determining the current playing time and the first playing time, the media file client may calculate a playing time difference between the current playing time and the first playing time. Illustratively, the current playing time is 1:29:00 and the first playing time is 1:28:30, so that the playing time difference between the current playing time 1:29:00 and the first playing time 1:28:30 is 30 seconds.

In sub-step 40517, the media file client calculates a target time difference between the second target play time and the first target play time.

After the media file client determines the second target playing time and the first target playing time, a target time difference between the second target playing time and the first target playing time can be calculated. For example, the second target playing time may be 1:31:10, and the first target playing time may be 1:30:30, so that the target time difference between the second target playing time 1:31:10 and the first target playing time 1:30:30 is 40 seconds.

In sub-step 40518, the media file client determines whether the target time difference is greater than the play time difference.

The media file client may compare the target time difference with the play time difference and determine whether the target time difference is greater than the play time difference. In the embodiment of the present disclosure, the target time difference is 40 seconds, the playing time difference is 30 seconds, and since 40 seconds is greater than 30 seconds, the media file client compares the target time difference with the playing time difference to determine that the target time difference is greater than the playing time difference.

In sub-step 40519, when the target time difference is greater than the play time difference, the media file client determines that the buffering progress of the data to be played is greater than the play progress of the currently played media file since the notification message was received.

If in sub-step 40518, the media file client determines that the target time difference is greater than the play time difference, it indicates that the buffering progress of the data to be played is greater than the play progress of the currently played media file since the notification message was received, and therefore, the media file client determines that the buffering progress of the data to be played is greater than the play progress of the currently played media file since the notification message was received.

In sub-step 4052, when the buffering progress of the data to be played is greater than the playing progress of the currently played media file from the time when the notification message is received, the media file client performs playing of the target media file according to the data to be played.

If in sub-step 4051, the media file client determines that the buffering progress of the data to be played is greater than the playing progress of the currently played media file from the time when the notification message is received, the media file client plays the target media file according to the data to be played.

For example, referring to fig. 4-10, it shows a flowchart of a method for a media file client to play a target media file according to data to be played, which is provided in the embodiment shown in fig. 4-1, and referring to fig. 4-10, the method may include the following steps:

in sub-step 40521, the media file client determines the data frame played at the current playing time among the data of the currently played media file.

The media file client may store information of playing data in a currently playing media file, where the information of playing data in the currently playing media file may include: the corresponding relationship between the playing data frame and the playing time includes the currently playing data frame and the played data frame, and the playing data frame in the playing data in the media file currently played by the media file client and the playing time of the playing data frame are recorded in the corresponding relationship between the playing data frame and the playing time. The media file client can query the corresponding relation between the playing data frame and the playing time according to the current playing time to obtain the data frame played at the current playing time. For example, the current playing time is 1:29:00, the media file client queries the corresponding relationship between the playing data frame and the playing time according to the current playing time 1:29:00 to obtain the data frame played at the current playing time 1:29:00, and the data frame played at the current playing time 1:29:00 may be the data frame V₉。

In sub-step 40522, the media file client determines a target data frame to be played that is the same as the data frame played at the current playing time in the buffer data of the data to be played.

The media file client may determine a target data frame to be played, which is the same as the data frame played at the current playing time, in the buffered data of the data to be played by comparing the data frame played at the current playing time with the data frame in the buffered data of the data to be played.

For example, the buffer data of the data to be played may be WW₇P₄P₂P₀V₀V₉M₁M₂The media file client end plays the data frame V at the current playing time₉Comparing with each data frame in the buffer data of the data to be played, and determining a target data frame V to be played which is the same as the data frame played at the current playing time in the buffer data of the data to be played₉。

In sub-step 40523, the media file client sequentially plays the target data frame to be played and the data to be played that is to be played after the playing time corresponding to the target data frame to be played in the buffered data of the data to be played.

After determining the target data frame to be played, the media file client may play the target data frame to be played and the data to be played that is to be played after the play time corresponding to the target data frame to be played in sequence, where the buffered data of the data to be played is WW₇P₄P₂P₀V₀V₉M₁M₂The target data frame to be played is V₉At the target data frame V to be played₉The data to be played after the corresponding playing time comprises: data frame M₁And a data frame M₂Therefore, the media file client end sequentially plays the target data frames to be played V₉Data frame M₁And a data frame M₂And subsequently buffered data.
