Technical Field

Background

When a video player is used for playing a video, if the video player is completely incompatible with the video, the video player may not complete video decoding, and thus the video cannot be played. If the video player is not completely incompatible with the video, the video player may be able to complete the video decoding and play the video, but the decoded video may have some problems.

At present, for a video to be played, if a display timestamp of the video decoded by a video player has a small jump and an audio display timestamp is normal, the video played by the video player will have a short pause or frame jump, and at this time, the video player will not quit playing but continue playing the video. However, the above problems in the video may cause a short pause or frame skipping phenomenon to the video being played, thereby affecting the playing quality of the video by the video player.

In order to better understand the technical solution provided by the embodiment of the present application, some brief descriptions are provided below for application scenarios to which the technical solution provided by the embodiment of the present application is applicable, and it should be noted that the application scenarios described below are only used for illustrating the embodiment of the present application and are not limited. In specific implementation, the technical scheme provided by the embodiment of the application can be flexibly applied according to actual needs.

The video detection method provided by the embodiment of the application can be applied to the application scene shown in fig. 1. Referring to fig. 1, the server 100 is communicatively connected to the terminal device 300 through a network 200, wherein the network 200 may be, but is not limited to, a local area network, a metropolitan area network, a wide area network, or the like, and the number of the terminal devices 300 connected to the server 100 may be plural. The terminal device 300 can transmit communication data and messages to and from the server 100 through the network 200.

The terminal 300 may be a portable device (e.g., a mobile phone, a tablet Computer, a notebook Computer, etc.), or may be a Computer, a smart screen, a Personal Computer (PC), etc. The server 100 may be a server or a server cluster or a cloud computing center composed of a plurality of servers, or a virtualization platform, and may also be a personal computer, a large and medium-sized computer, or a computer cluster, etc. According to implementation needs, the application scenario in the embodiment of the present application may have any number of terminal devices and servers. The embodiment of the present application is not particularly limited to this.

For example, a client of a certain playing video player is installed on the terminal device 300, and an online video provided on a certain playing video platform corresponding to the server 100 or a local video stored on the terminal device 300 may be played through the client of the certain playing video player.

The terminal device 300 may further record a video and upload the recorded video to the server 100, or acquire a locally stored video and upload the video to the server 100, and distribute the video to a certain video playing platform through the server 100, or the server 100 may further acquire a video through another path, such as acquiring a video from a network or another server, and distribute the acquired video on a certain video playing platform.

In the related art, when a client of a certain broadcast video player is used by a terminal device to play an online video published on a certain broadcast video platform, the video player is required to decode a video file of the online video and play the online video based on the decoded video file. If the video player can complete decoding of the video, even if the video file obtained through decoding has the problems of small-amplitude jump of a display timestamp and the like, the video player can continue to play the video, so that the phenomenon of short pause or frame jump and the like can occur in the process of playing the video by the video player, and the playing quality of the video by the video player is influenced.

Based on this, when the method is applied to a server, before the server issues a video to a video playing platform, a target video player may be called to perform decapsulation operation on the video to be detected, so as to obtain playing information of a video file. And then, detecting the playing information of the video file to obtain target information, and determining a compatibility evaluation result of the target video player to-be-detected video according to the target information. And finally, determining whether to release the video to be detected to the video playing platform according to the determined compatibility evaluation result.

For example, before a server of a certain broadcast video platform releases a video, a certain broadcast video player can be used as a target video player, a compatibility evaluation result of the certain broadcast video player for a video to be detected is determined by the method, and when the compatibility evaluation result meets a requirement, the video can be released to the certain broadcast video platform. Therefore, when the terminal equipment plays the video published on a certain playing video platform by using a certain playing video player, the phenomena of short pause or frame skipping and the like in the playing process can be avoided, the playing quality of the video player on the video is further improved, and the film watching experience of a user when the user watches the video by using the video player is increased.

Fig. 2 shows a flowchart of a video detection method provided in an embodiment of the present application, where the method may be executed by the server 100 in fig. 1, or may be executed by a terminal device or other electronic devices. Illustratively, the following describes a specific implementation process of the video detection method according to the embodiment of the present application, with a server for video detection as an execution subject. The specific implementation process performed by other devices is similar to the process performed by the server alone, and is not described herein again.

As shown in fig. 2, the video detection method includes the following steps:

step S201, a target video player is used to obtain playing information of a video file from the video file of the video to be detected.

The target video player can be any video player. For example, for a server of a certain video playing platform, a short video recorded and distributed by a user through a client of a certain video playing player may be acquired, or a video may be acquired from a network. After the server acquires the video, the video needs to be detected first.

The server may decapsulate the video file of the video to be detected by using the target video player to obtain the playing information of the video file. The playback information may include at least one of the following information: PTS information and DTS information of each data frame of the video file, coding type of the video file, audio playing time, video playing time, total playing time, playing control parameters and the like of the video file. For example, after the server uses the target video player to decapsulate the video file of the video to be detected, the playing information of the video file as shown in fig. 3 may be displayed. As shown in fig. 3, the encoding type of the video file is H265 format, the audio playing time of the video file is 120min, the video playing time of the video file is 121min, the total playing time of the video file is 120min, and the playing control parameter is M3U8 content.

In an embodiment, by configuring the player parameters, the decoding and synchronizing module in the target video player may be skipped, and only the decapsulating module in the target video player is used to perform decapsulation on the video file of the video to be detected. By performing decapsulation operation on the video to be detected, code stream information such as PTS/DTS information, coding type, total playing time and the like of each data frame of the video file can be obtained.

Step S202, the playing information of the video file is detected to obtain the target information.

The server is provided with a detection module, and the target video player unpacks the video file of the video to be detected to obtain the playing information of the video file, and then can transmit the playing information of the video file into the detection module in a dotting mode. The detection module can detect the playing information of the video file to obtain target information which is used for indicating that the playing information of the video file is unmatched with the target video player. The dotting mode is to input the playing information of the video file into the detection module according to a certain time interval.

Step S203, based on the target information, determining a compatibility evaluation result of the target video player to the video to be detected.

The information types corresponding to the prompt information contained in the target information can be determined, and then the value of the compatibility evaluation result of the target video player to be detected can be determined according to the number of the obtained information types. And determining the value of the compatibility evaluation result of the target video player to be detected according to the number of the prompt messages corresponding to each message type.

Because the target information includes information used for indicating that the playing information of the video file is unmatched with the target video player, a compatible evaluation result of the target video player for the video to be detected can be determined according to the target information. When the unmatched information in the target information is less, the compatible evaluation result is better; when the mismatch information in the target information is more, the compatibility evaluation result is worse. For example, the determined compatibility evaluation result may be as shown in fig. 4, where fig. 4 shows that the video to be detected has a problem that the PTS of the xx frame of the video has a 3s jump and the score of the video is 8, and according to the compatibility evaluation result, it may be determined that the target information has less mismatch information and the compatibility evaluation result is better.

And step S204, determining a processing strategy for the video to be detected according to the compatibility evaluation result.

After determining the compatible evaluation result of the target video player for the video to be detected, the processing strategy for the video to be detected can be determined according to the compatible evaluation result.

In an embodiment, the server may determine whether to distribute the video to be detected to the video platform corresponding to the target video player according to the compatibility evaluation result. When the compatibility evaluation result meets the set requirement, the server can issue the video to be detected to the video platform corresponding to the target video player, and when the compatibility evaluation result does not meet the set requirement, the server can output target information, namely information unmatched with the target video player exists in the playing information of the output video file.

In another embodiment, the server may further determine whether to use the target video player to play the video to be detected or to start the standby video player to play the video to be detected according to the compatibility evaluation result. When the compatibility evaluation result meets the set requirement, the server can inform the terminal device to play the video to be detected by using the target video player, and when the compatibility evaluation result does not meet the set requirement, the server can inform the terminal device to start the standby video player to play the video to be detected.

According to the video detection method provided by the embodiment of the application, the target video player can be adopted to obtain the playing information of the video file from the video file of the video to be detected, the target information can be obtained by detecting the playing information of the video file, the target information comprises information used for indicating that the playing information is unmatched with the target video player, and based on the target information, the compatibility evaluation result of the target video player to be detected can be determined. Before the video to be detected is played, whether the target video player is used for playing the video to be detected is determined according to the determined compatibility evaluation result of the video to be detected, and when the compatibility evaluation result meets the requirement, the target video player is used for playing the video to be detected, so that the playing quality of the video player to the video can be improved.

In an embodiment, the playing information of the video file may include timestamp information of each data frame of the video file, and in the step S202, the target information may be obtained as follows: the PTS and DTS of each data frame of the video file are detected, and when the target information is detected to meet the first set condition, first prompt information used for representing the error of the time stamp information can be recorded in the target information. The first setting condition includes at least one of:

the PTS of any two adjacent data frames in the video file generates the jump of first set time;

the DTS of any two adjacent data frames in the video file generates jumping of a second set time;

any data frame in the video file does not contain PTS or DTS;

any one data frame in the video file does not contain PTS and DTS.

For example, when the PTS of any two adjacent data frames in the video file makes a jump of 1s or 2s or more, a PTS error of the video file may be recorded in the target information.

When a 100ms jump occurs in the DTS of any two adjacent data frames in a video file, a PTS error of the video file can be recorded in the target information. As shown in fig. 5, the DTS of the nth frame of the video may be 300ms, and the DTS of the (n + 1) th frame of the video may be 400ms, and then the transition of 100ms occurs between the DTSs of the nth frame and the DTS of the (n + 1) th frame of the video.

In another embodiment, the playing information of the video file may include the encoding type of the video file, and in step S202, the target information may be obtained as follows: detecting the coding type of the video file, and if the coding type is not detected to include a network abstraction layer unit, recording second prompt information for representing the lack of the network abstraction layer unit in the target information; and if the detected network abstraction layer unit in the coding type does not accord with the second set condition, recording third prompt information for representing the network abstraction layer unit error in the target information. Wherein the second setting condition at least comprises one of the following conditions:

the sequence parameter set, the image parameter set or the video parameter set contained in the network abstraction layer unit are not located at the set position;

the network abstraction layer unit includes only the specific information.

Specifically, each data frame of the video file may be parsed, and only the data frames in the H264 and H265 formats may be parsed, and if the NALU is not parsed, the second hint information for indicating the lack of the NALU may be recorded in the target information. When it is detected that a Sequence Parameter Set (SPS), a Picture Parameter Set (PPS), or a Video Parameter Set (VPS) included in the NALU is not located at a Set position, or only specific information is included in the NALU, third hint information for characterizing a NALU error may be recorded in the target information.

Among them, H264 and H265 are both video encoding formats, that is, video compression methods, and since the code stream of the video itself is too large, the video needs to be compressed and then transmitted through a network. H264 is a compression method which is currently the mainstream, and is generally adopted by video conference equipment. H265 may also be referred to as High Efficiency Video Coding (HEVC), which is an upgraded version of H264, and can further improve the compression ratio of the Video, and has outstanding performance in terms of improving the Video quality and reducing the capacity, i.e., saving the bandwidth, in the aspect of low-bit-rate Video compression.

For example, NALU errors of a video file may be recorded in the target Information when it is detected that the SPS/PPS/VPS is not in the packet header, or when it is detected that the SPS/PPS/VPS is not followed by an I-frame, or when it is detected that only Supplemental Enhancement Information (SEI) is included in the packet of the NALU.

In another embodiment, the playing information of the video file may include an audio playing time, a video playing time, and a total playing time of the video file, and in the step S202, the target information may be obtained as follows: and detecting the audio playing time, the video playing time and the total playing time of the video file, and recording fourth prompt information for representing that the playing time information is wrong in the target information when the target information is detected to meet the third set condition. The third setting condition includes at least one of:

the audio playing time is not equal to the video playing time;

the audio playing time is greater than the total playing time;

the video playing time is greater than the total playing time.

In another embodiment, the playing information of the video file may include playing control parameters, and in step S202, the target information may be obtained as follows: and detecting the playing control parameter, and if the playing control parameter does not accord with a fourth set condition, recording fifth prompt information for representing the error of the playing control parameter in the target information. Wherein the fourth setting condition includes at least one of:

determining that the total playing time of the video file is less than a set threshold value according to the playing control parameters;

determining that the video file lacks a set initialization fragment according to the playing control parameter; the initialization fragment is used for initializing a video file when the resolution of the video to be detected is switched.

For example, the playback control parameter may be M3U8 content, the M3U8 content is detected, and if the M3U8 content is not standardized, fifth prompting information for indicating that the playback control parameter is incorrect is recorded in the target information. The method specifically comprises the following steps: when it is detected that the total playing time of the video file is less than the set threshold, or when it is detected that the playing time lengths of the audio data and the video data of the video file are not aligned, or when it is detected that fmp4 lacks initialization fragmentation, fifth prompt information for indicating an error of the playing control parameter may be recorded in the target information. fmp4 initialization slices are used to initialize video files when the resolution of the video to be detected is switched, and different resolutions require different initialization files. The fmp4 initialization segment can also be used for replacing other film sources after inserting advertisements in the M3U8 content, and initializing video files when videos to be detected of different film sources are spliced into the M3U8 content.

The M3U8 file refers to an M3U file in Universal Character Set Transformation Format (UTF) -8 encoding Format. The M3U file is a plain text file for recording index, when the M3U file is opened, the playing software does not play the file, but finds out the network address of the corresponding audio/video file according to the index for online playing.

In some embodiments, the server transmits the playing information of the video file to the detection module for detection, and after the target information is obtained, a compatibility evaluation result of the target video player for the video to be detected can be determined according to the target information, and the compatibility evaluation result can be represented in a score form. For example, when the target information indicates that there is no error in the playing information of the video file, it may be determined that the value of the compatibility evaluation result of the video to be detected by the target video player is 10 points full. When the target information indicates that a slight error exists in the playing information of the video file but does not affect the target video player to play the video file, it may be determined that the value of the compatibility evaluation result of the target video player to the video to be detected is 9 points. When the target information indicates that a slight error which can be compatible with the target video player exists in the playing information of the video file, the value of the compatibility evaluation result of the target video player for the video to be detected can be determined to be 8 points. When the target information indicates that a relatively serious error that the target video player can be compatible exists in the playing information of the video file, the value of the compatibility evaluation result of the target video player for the video to be detected can be determined to be 7 points. When the target information indicates that an error affecting the viewing experience of the user exists in the playing information of the video file, the value of the compatibility evaluation result of the target video player to be detected video can be determined to be 6 points. When the target information indicates that an error that the target video player reports an error to exit exists in the playing information of the video file, the value of the compatibility evaluation result of the target video player for the video to be detected can be determined to be 5 points.

Illustratively, this may be shown in the following table:

score of	Description of the invention
		10 (score)	Without error
9	Slight error does not affect
		8	Light minor errors that a player can be compatible with
7	More serious errors that a player can be compatible with
		6	Affecting the viewing experience
5	Player error reporting exit

Specifically, in some embodiments, after the server obtains the target information, a value of a compatibility evaluation result of the target video player for the video to be detected may be determined according to the number of information types included in the target information. Illustratively, the information types included in the target information for indicating that the playing information of the video file is unmatched with the target video player are five, namely first prompt information for representing a timestamp information error, second prompt information for representing that a network abstraction layer unit is absent, third prompt information for representing a network abstraction layer unit error, fourth prompt information for representing a playing time information error and fifth prompt information for representing a playing control parameter error. If the target information obtained by detecting the video to be detected only comprises one of the five information types, the compatibility evaluation result can be determined to be 9 points, if the obtained target information comprises two of the five information types, the compatibility evaluation result can be determined to be 8 points, if the obtained target information comprises three of the five information types, the compatibility evaluation result can be determined to be 7 points, if the obtained target information comprises four of the five information types, the compatibility evaluation result can be determined to be 6 points, and if the obtained target information comprises all the five information types, the compatibility evaluation result can be determined to be 5 points.

In other embodiments, after the server obtains the target information, the value of the compatibility evaluation result of the target video player for the video to be detected may be determined according to the number of the prompt messages of each information type included in the target information. Specifically, a score may be set for each information type, and the information type may be deducted according to the number of detection errors of a certain information type included in the target information. The number of detection errors is the number of the prompt messages. For example, the score of each information type may be set to 10 points, the score of the information type may be decremented by 2 when 1 detection error exists in a certain information type, the score of the information type may be decremented by 4 when 2 detection errors exist in a certain information type, and the score of the information type may be decremented by 6 when 3 detection errors exist in a certain information type. And finally, determining the value of the compatible evaluation result according to the scores of all information types included in the target information.

In other embodiments, the server may also determine, according to the total amount of the prompt information included in the target information, a value of a compatibility evaluation result of the target video player for the video to be detected. The more the total number of the prompt messages contained in the target message, the lower the value of the compatible evaluation result, and the less the total number of the prompt messages contained in the target message, the higher the value of the compatible evaluation result. For example, if the total number of the types of prompt information included in the target information is lower than a first number threshold, the compatibility evaluation result may be determined to be 10 points, and if the total number of the types of prompt information included in the target information is lower than a second number threshold, the compatibility evaluation result may be determined to be 8 points. Wherein the second number threshold is greater than the first number threshold.

In other embodiments, after the server obtains the target information, the server may further determine a severity of the detection error according to the detection error included in the target information, determine the compatibility evaluation result according to the severity of the detection error, and determine a value of the compatibility evaluation result. For example, after the server detects the video to be detected, the obtained target information includes a detection error that is a jump of display timestamp information of any two adjacent data frames in the video file within a first set time, according to the detection error, the severity of the detection error can be determined to be very slight, then the compatibility evaluation result is determined to be that a slight error exists in the playing information but the playing of the video to be detected by the target video player is not affected, and the value of the compatibility evaluation result can be 9 minutes. For another example, after the server detects the video to be detected, the detection error included in the obtained target information is that the network abstraction layer unit only includes the specified information, according to the detection error, it may be determined that the severity of the detection error is severe, and then it is determined that the compatibility evaluation result is that the playing information has a severe error but does not affect the compatibility of the target video player with the video to be detected, and the value of the compatibility evaluation result may be 7 minutes.

In an embodiment, after determining a compatibility evaluation result of a video to be detected by a target video player, the compatibility evaluation result may be displayed to a technician, and the technician may determine whether to issue the video to be detected to a video platform corresponding to the target video player according to a value of the compatibility evaluation result. And when the value of the compatibility evaluation result meets the set threshold range, the video to be detected can be issued to the video platform corresponding to the target video player. And when the value of the compatible evaluation result does not meet the set threshold range, target information can be output. For example, the set threshold range may be 7 minutes, when the value of the compatibility evaluation result is greater than 7 minutes, the video to be detected may be issued to the video platform corresponding to the target video player, and when the value of the compatibility evaluation result is less than or equal to 7 minutes, the corresponding error existing in the video to be detected or the target video player may be output.

When the value of the compatible evaluation result is determined not to meet the set threshold range, the video to be detected cannot be issued to the video platform corresponding to the target video player, and the technical personnel can re-encode the video file of the video to be detected according to the output target information to solve the problem and then issue the video to be detected to the video platform corresponding to the target video player.

In some embodiments, the server may be provided with a detection tool for detecting whether the target video player is compatible with a certain video to be detected, where the detection tool may include the target video player, a detection module, a problem reporting module, and a report generating module, and all the modules cooperate with each other to complete the video detection method described above.

In particular, fig. 6 shows a detailed process for detecting whether a target video player is compatible with a video to be detected by using a detection tool. As shown in fig. 6, the process may include the steps of:

step S601, the target video player obtains playing information of the video file from the video file of the video to be detected.

The detection tool starts a target video player without synchronization through configuration parameters, in order to improve detection efficiency, shield a decoding process and only carry out decapsulation operation, the playing information such as PTS information and DTS information of each data frame of a video file of a video to be detected, the coding type of the video file, the audio playing time, the video playing time, the total playing time and the playing control parameters of the video file can be obtained.

Step S602, the target video player sends the playing information of the video file to the detection module.

In each frame cycle of decapsulating a video file of a video to be detected, a target video player may transmit playing information of each frame of the video file to a detection module in a dotting manner.

Step S603, the detection module detects the playing information of the video file to obtain the target information.

The detection module can detect the playing information of the video file to obtain target information which is used for indicating that the playing information of the video file is unmatched with the target video player.

Step S604, the detection module sends the target information to the problem reporting module.

Step S605, the detection module determines the score of the compatibility evaluation result of the video file according to the target information.

In step S606, the problem reporting module sends the target information and the score of the compatible evaluation result to the report generating module.

After receiving the target information, the problem reporting module can determine the qualitative score of the video file according to the target information and transmit the score of the target information and the compatible evaluation result to the report generating module.

And step S607, the report generating module classifies and sorts the scores of the target information and the compatible evaluation result and generates a report file.

After the video to be detected is played, the report generation module can summarize and sort the received target information and the score of the compatible evaluation result to generate a report file. The server can determine whether the target video player is compatible with the video to be detected according to the report file generated by the report generation module.

In another embodiment, the terminal device or a target video player installed on the terminal device may independently complete decapsulation of the video file, detection of playing information of the video file, and determination of a compatibility evaluation result, that is, the video detection method provided in this embodiment of the present application may be executed by the terminal device or the target video player installed on the terminal device. Before the target video player is used for playing the video to be detected, the terminal equipment can adopt the target video player to obtain playing information of the video file from the video file of the video to be detected, detect the playing information of the video file to obtain target information, and determine a compatibility evaluation result of the target video player on the video to be detected based on the target information. If the value of the compatibility evaluation result meets the set threshold range, a target video player is adopted to play the video to be detected; and if the value of the compatibility evaluation result does not meet the set threshold range, starting a standby video player to play the video to be detected.

Based on the same inventive concept as the above embodiments, the embodiments of the present application further provide a video playing control method, which can be executed by a terminal device. The method may comprise the steps of: and responding to the playing operation triggered by the target video player aiming at the target video, starting a standby video player, and playing the target video through the standby video player. The standby video player is started when the value of the target video player on the compatibility evaluation result of the target video is determined not to meet the set threshold range; the compatibility evaluation result is determined based on target information obtained by detecting the playing information of the video file of the target video; the playing information of the video file is obtained by the target video player from the video file of the target video.

On the basis of the foregoing embodiments, fig. 7 shows a flowchart of a video playing control method provided in an embodiment of the present application, where the method may be executed by the terminal device 300 in fig. 1, or may be executed by both the server 100 and the terminal device 300. Illustratively, the following describes a specific implementation procedure of the video playback control method according to the embodiment of the present application, with a terminal device for controlling video playback as an execution subject. Are not described in detail herein.

As shown in fig. 7, the video playback control method includes the following steps:

step S701, in response to a play operation triggered by the target video player for the target video, determining a compatibility evaluation result of the target video player for the target video.

In an embodiment, in response to a play operation triggered by a user for a target video through a target video player on a terminal device, the terminal device may first invoke a decapsulation module of the target video player to perform decapsulation operation on a video file of the target video, so as to obtain play information of the video file. And then, the playing information of the video file can be detected, target information used for indicating that the playing information is unmatched with the target video player is obtained, and a compatibility evaluation result of the target video player for the target video is determined based on the target information. The specific implementation manner in the process may be executed by referring to the steps described above, and will not be described herein again.

In another embodiment, in response to a play operation triggered by a user for a target video through a target video player on a terminal device, the terminal device may first invoke a decapsulation module of the target video player to perform decapsulation operation on a video file of the target video, so as to obtain play information of the video file. And then sending the playing information of the video file to a server. After receiving the playing information of the video file, the server can detect the playing information to obtain target information and send the target information to the terminal equipment. After receiving the target information, the terminal device can determine a compatibility evaluation result of the target video player on the target video.

Step S702, determining whether the value of the compatibility evaluation result meets a set threshold range; if not, executing step S703; if so, step S704 is performed.

Step S703, outputting a prompt message for starting the standby video player to play the target video.

Step S704, the target video is played by the target video player.

After the terminal device determines the compatibility evaluation result of the target video player on the target video, when the value of the compatibility evaluation result meets the set threshold range, the terminal device can directly play the target video through the target video player. When the value of the compatibility evaluation result does not meet the set threshold range, the terminal device may output prompt information for starting the standby video player to play the target video to the user.

Step S705, determining whether to start a standby video player to play the target video; if not, executing step S706; if so, step S707 is executed.

Step S706, quitting playing.

In step S707, the standby video player is started.

The terminal equipment can determine whether to start the standby video player to play the target video according to the selection of the user. If the user selects not to start the standby video player, the terminal equipment responds to the operation of not starting the standby video player to play the target video and quits playing; and if the user selects to start the standby video player, the terminal equipment responds to the operation of starting the standby video player to play the target video, and starts the standby video player.

In some embodiments, when the value of the compatibility evaluation result of the target video player for the target video does not satisfy the set threshold range, the terminal device may search and determine a plurality of standby video players capable of playing the target video. The terminal equipment can display prompt information that the target video player is not suitable for playing the target video on the display interface, and display the identifiers of the standby video players on the display interface, so that a user can select any one video player from the standby video players to play the target video according to own preference, and personalized requirements of the user are met.

In step S708, the target video is played by the standby video player.

When the user determines to start the standby video player to play the target video, the terminal device may start the standby video player and play the target video through the standby video player in response to an operation of starting the standby video player to play the target video. When the user determines that the standby video player is not started to play the target video, the terminal device can quit the target video player and no longer play the target video in response to the operation that the standby video player is not started to play the target video.

For example, after receiving an operation of a user to play a target video through a target video player, the terminal device may determine a compatibility evaluation result of the target video player for the target video, and may output the prompt information shown in fig. 8 when determining that a value of the compatibility evaluation result does not satisfy a set threshold range. In fig. 8, if the user selects the "ok" button, the terminal device starts the standby video player in response to an operation of the user starting the standby video player, and plays the target video through the standby video player. If the user selects the "cancel" button, the terminal device exits the target video player in response to the user not initiating operation of the standby video player.

In the video detection method provided by the above embodiment, the target video player may be adopted to obtain the playing information of the video file from the video file of the video to be detected, and the target information may be obtained by detecting the playing information of the video file, where the target information includes information used to indicate that the playing information is not matched with the target video player, and based on the target information, a compatibility evaluation result of the target video player with the video to be detected may be determined. And when the target video player is determined to be incompatible with the video to be detected according to the compatibility evaluation result, the video to be detected can be played without adopting the target video player, so that the playing quality of the video player can be improved, and the film watching experience of a user when the user watches the video by adopting the video player is increased.

In other embodiments, when it is determined that the value of the compatibility evaluation result of the target video player for the target video does not satisfy the set threshold range, the terminal device may first obtain the playing information of the video file from the video file of the target video by using the standby video player, detect the playing information of the video file, determine the compatibility evaluation result of the standby video player for the target video, and then determine whether to use the standby video player to play the target video according to the compatibility evaluation result. The process of determining the compatibility evaluation result of the target video by the standby video player is similar to the process of determining the compatibility evaluation result of the target video by the target video player, and is not repeated here. If the value of the compatibility evaluation result of the standby video player on the target video does not meet the set threshold range, other standby video players are continuously searched; when the value of the compatibility evaluation result of the standby video player on the target video meets the set threshold range, the terminal device can output prompt information for starting the standby video player to play the target video. By the method, the phenomena of blocking or frame skipping and the like when the target video is played by the standby video player can be avoided, the playing quality of the target video is further ensured, and the watching experience of a user is improved.

In other embodiments, when it is determined that the value of the target video player with respect to the compatibility evaluation result of the target video does not satisfy the set threshold range, the terminal device may search and determine a plurality of standby video players capable of playing the target video, and display the identifiers of the plurality of standby video players on the display interface, so that a user may select any one of the plurality of standby video players to play the target video. After the terminal device determines the target standby video player selected by the user, the terminal device may first determine a result of the compatibility evaluation of the target standby video player on the target video, and a process of determining the result of the compatibility evaluation of the target standby video player on the target video is similar to a process of determining the result of the compatibility evaluation of the target video player on the target video, and is not repeated here. If the value of the compatibility evaluation result of the target video by the target standby video player meets the set threshold range, the terminal equipment can start the target standby video player to play the target video. By the method, the phenomena of pause or frame skipping and the like when the target video is played by the target standby video player can be avoided, and the playing quality of the target video is further ensured. And if the value of the compatibility evaluation result of the target video player to the target video does not meet the set threshold range, outputting prompt information and recommending the user to select other standby video players to play the target video.
