It should be noted that the history record corresponding to the current account information may be obtained, the video watching records corresponding to the target user are searched from the history record, that is, the video watching records are all the watching records of the target user, and then the video watched when the application program is closed last time is selected from the video watching records, and the video is taken as the target video.
Step S30, obtaining a streaming media file format corresponding to the target video, and selecting a target streaming media file format from the streaming media file formats according to preset format information.
It should be noted that there are various streaming media file formats, including AVI file format, MPEG file format, and the like, and other file formats may also be used, which is not limited in this embodiment.
It will be appreciated that for a video application, there may be multiple file formats for a video in its platform server to meet the viewing needs of different users. The preset format information is a file format supported by the terminal device, and a target streaming media file format is selected from the streaming media file formats according to the preset format information.
It should be noted that there are multiple streaming media file formats corresponding to the target video in the platform server, and it is known that the terminal device supports two or more streaming media file formats according to the preset format information, at this time, the file format priority needs to be extracted from the preset format information, and one streaming media file format with the highest priority is selected from the multiple streaming media file formats according to the file format priority as the target streaming media file format.
In particular implementations, for example: the streaming media file formats corresponding to the target video can be format A, format B and format C, the streaming media file formats supported by the terminal equipment can be known to be format A and format B according to the preset format information, the file format priority is extracted from the preset format information, and the priority of the format A is known to be higher than that of the format B according to the file format priority, so that the format A is taken as the target streaming media file format.
Step S40, downloading target streaming media data according to the target video and the target streaming media file format, and separating video data and audio data from the target streaming media data.
It should be understood that after determining the target video and target streaming media file formats, the target streaming media data may be downloaded from the platform server, and then for better playing effect, the video data and the audio data may be separated from the target streaming media data, and then the video data and the audio data are decompressed and played, respectively.
Step S50, decoding the video data and the audio data respectively to obtain target video data and target audio data, and playing the target video data and the target audio data.
It can be understood that the target video data is decompressed video data, the target audio data is decompressed audio data, and video playing can be completed by playing the target video data and the target audio data.
In the embodiment, when the video application is detected to be started, the current user information is acquired, and the target user is determined according to the current user information; searching a video watching record corresponding to the target user, and determining a target video according to the video watching record; acquiring a streaming media file format corresponding to the target video, and selecting a target streaming media file format from the streaming media file format according to preset format information; downloading target streaming media data according to the target video and the target streaming media file format, and separating video data and audio data from the target streaming media data; and respectively decoding the video data and the audio data to obtain target video data and target audio data, and playing the target video data and the target audio data. Therefore, the target user is determined according to the current user information, the target video is determined from the video watching record, the data of the target video is downloaded in a streaming media mode and decompressed and played, and the user can see the video which is not seen before when starting the video application.
In an embodiment, as shown in fig. 3, a second embodiment of the video playing method based on streaming media according to the present invention is proposed based on the first embodiment, and the step S10 includes:
step S101, when detecting that the video application is started, acquiring current user information.
It should be noted that, when it is detected that the video application is started, current user information of a user currently using the terminal device is obtained, where the current user information includes current account information and current face information, and may also include other information, which is not limited in this embodiment.
It can be understood that the account information of the user is stored in the video application, and the account is automatically logged in when the video application is started, so that the current account information logged in the video application can be acquired when the video application is detected to be started.
It can be understood that cameras can be arranged on various current terminal devices, and when the terminal devices are used for watching videos, the distance between a user and the terminal devices is not too far, so that the current face information of the user can be acquired through the cameras on the terminal devices.
The specific way of acquiring the current face information may be: when the video application is detected to be started, the current user image is acquired through the camera, face recognition is performed on the current user image, current face information is obtained, and the current face information can also be obtained through other modes.
And step S102, extracting current account information and current face information from the current user information.
It can be understood that when the video application is detected to be started, the current user information is acquired, then the current account information and the current face information can be extracted from the current user information, and the target user is determined according to the current account information and the current face information.
Step S103, searching the face information to be processed corresponding to the current account information, and matching the target face information corresponding to the current face information from the face information to be processed.
It should be noted that, in a general household, there may be a case where a plurality of people commonly use an account of a video application, so that face information of a user using the account can be collected in advance, and a mapping relationship between the face information and the account information of the account is established, so that after the current account information is acquired, to-be-processed face information corresponding to the current account information can be determined according to the mapping relationship.
It should be understood that after the face information to be processed is determined, there may be one or more face information to be processed, and therefore, the target face information corresponding to the current face information may be matched from the face information to be processed.
In particular implementations, for example: in a four-family house, a user A, a user B, a user C and a user D commonly use a video account A, face information of the four users can be collected in advance and respectively taken as face information A, face information B, face information C and face information D, and mapping relations between the four face information and the video account A are established, so that when the current account information is determined to be the video account A and the current face information is determined to be the face information X, the face information A, the face information B, the face information C and the face information D corresponding to the video account A can be searched according to the mapping relations, at the moment, the face information A, the face information B, the face information C and the face information D are face information to be processed, then target face information corresponding to the current face information is matched from the face information to be processed, namely, the face information X is judged to be the face information A, the face information B, the face information C and the face information D, The face information A is used as the target face information if the face information X is matched with the face information A; and if the face information X is not matched with the four face information, normally entering a video application home page.
And step S104, searching target user information corresponding to the target face information, and determining a target user according to the target user information.
It can be understood that after the target face information is determined, the target user information corresponding to the target face information can be searched, and then the target user is determined according to the target user information.
In a specific implementation, for example, when the target face information is face information a, the target user is user a.
In the embodiment, when the video application is detected to be started, the current user information is acquired; extracting current account information and current face information from the current user information; searching the face information to be processed corresponding to the current account information, and matching target face information corresponding to the current face information from the face information to be processed; and searching target user information corresponding to the target face information, and determining a target user according to the target user information. Therefore, when the video application is started, the target user is determined according to the current user information, the video is played for the target user in a targeted mode, and the individuation of video playing is improved.
In an embodiment, as shown in fig. 4, a third embodiment of the video playing method based on streaming media of the present invention is proposed based on the first embodiment or the second embodiment, and in this embodiment, the description is made based on the first embodiment, and the step S40 includes:
step S401, determining target streaming media data according to the target video and the target streaming media file format.
Further, the step S401 includes:
searching for to-be-selected streaming media data corresponding to the target video, and acquiring to-be-selected streaming media file formats corresponding to the to-be-selected streaming media data; and selecting target streaming media data from the streaming media data to be selected according to the format of the streaming media file to be selected and the format of the target streaming media file.
It should be noted that after the target video and the target streaming media file format are determined, to-be-selected streaming media data corresponding to the target video may be searched, and to-be-selected streaming media file formats corresponding to the to-be-selected streaming media data are obtained, for example, there may be two to-be-selected streaming media data corresponding to the target video, the two to-be-selected streaming media data respectively have different to-be-selected streaming media file formats, and it is necessary to select one of the two to-be-selected streaming media data as the target streaming media data, where the streaming media file format of the target streaming media data is the same as the target streaming media file format.
Step S402, searching the target stream media name and the target network speed corresponding to the target stream media data.
It should be noted that, in the platform server, for convenience of distinction, each streaming media has its corresponding streaming media name, and the streaming media name may be a chinese character or other characters, which is not limited in this embodiment.
It should be understood that, in order not to affect the watching fluency of the user, different network speed requirements can be set for different streaming media data, and only when the network speed of the user meets the network speed requirement, the streaming media data is transmitted, so as to avoid the influence on the playing effect due to the fact that the video watching is jammed due to insufficient network speed of the terminal device of the user.
It is understood that the database of the platform server may be searched for a target streaming media name corresponding to the target streaming media data and a target internet speed required for downloading the target streaming media data.
Step S403, acquiring a current network speed, and determining whether the current network speed is greater than the target network speed.
It can be understood that the terminal device obtains the current network speed, and judges whether the current network speed is greater than the target network speed, and when the current network speed is not greater than the target network speed, generates an information prompt containing a network fault, and displays the information prompt to a user.
Step S404, when the current network speed is higher than the target network speed, downloading the target streaming media data from a preset server according to the target streaming media name.
It can be understood that, when the current network speed is higher than the target network speed, it indicates that the terminal device meets the condition for downloading the target streaming media data, so that the target streaming media data can be downloaded from a preset server according to the name of the target streaming media, where the preset server is the platform server.
Step S405, separating video data and audio data from the target streaming media data.
It is to be understood that, in downloading the target streaming media data, the video data and the audio data are separated from the target streaming media data for the convenience of decoding and playing.
In the embodiment, target streaming media data are determined according to the target video and the target streaming media file format; searching a target streaming media name and a target network speed corresponding to the target streaming media data; acquiring the current network speed, and judging whether the current network speed is greater than the target network speed; when the current network speed is higher than the target network speed, downloading the target streaming media data from a preset server according to the target streaming media name; and separating video data and audio data from the target streaming media data. Therefore, the target streaming media data and the corresponding target streaming media name are determined, the target streaming media is downloaded according to the target streaming media name, and the network speed verification is carried out before downloading, so that the smoothness of downloading the target streaming media data is ensured, and the risk of downloading failure or jamming is reduced.
In an embodiment, as shown in fig. 5, a fourth embodiment of the video playing method based on streaming media of the present invention is proposed based on the first embodiment or the second embodiment, and in this embodiment, the description is made based on the first embodiment, and the step S50 includes:
step S501, the video data is stored in a video data decoding buffer area, and the audio data is stored in an audio data decoding buffer area.
It should be noted that after the video data and the audio data are obtained, the video data are stored in the video data decoding buffer area, the audio data are stored in the audio data decoding buffer area, and when the data amount in the decoding buffer area reaches a preset threshold value, the data are decoded and played.
Step S502, obtaining the audio data amount of the audio data cached in the audio data decoding cache region.
It should be understood that, since the video data and the audio data are corresponding, whether to start decoding can be determined by determining the amount of audio data buffered in the audio data decoding buffer, and whether to start decoding can also be determined by determining the amount of video data buffered in the video data decoding buffer.
It is to be understood that, since the downloading of the target streaming media data is a continuous process, the process of obtaining the video data and the audio data and storing the video data and the audio data in the buffer is also a continuous process in which the audio data amount of the audio data buffered in the audio data decoding buffer is continuously obtained.
In step S503, it is determined whether the audio data amount is equal to a preset data amount threshold.
It should be noted that, the preset data amount threshold is set by the user according to the actual situation, and this embodiment does not limit this.
It should be understood that, determining whether the audio data amount is equal to the preset data amount threshold, when the audio data amount is smaller than the preset data amount threshold, not decoding first; when the audio data volume is equal to a preset data volume threshold value, decoding the audio data cached in the audio data decoding cache region; since decoding is started when the amount of audio data is equal to the preset data amount threshold, there is no case where the amount of audio data is larger than the preset data amount threshold in principle, and if such a case occurs, a decoder failure is declared, and decoder failure information is generated.
Step S504, when the audio data amount is equal to the preset data amount threshold, decoding the audio data cached in the audio data decoding cache region to obtain target audio data.
It can be understood that, by decoding the audio data buffered in the audio data decoding buffer, the target audio data can be obtained, where the target audio data is the decoded audio data.
Step S505, decoding the video data cached in the video data decoding cache region to obtain target video data.
It should be understood that, since the video data corresponds to the audio data, the video data buffered in the video data decoding buffer is also decoded at the same time when the audio data starts to be decoded, so as to obtain the target video data, where the target video data is the decoded video data.
Step S506, acquiring an audio playing time point corresponding to the target audio data, and acquiring a video playing time point corresponding to the target video data.
It should be noted that the decoded target audio data carries an audio playing time point, and the decoded target video data carries a video playing time point, so that the audio playing time point corresponding to the target audio data and the video playing time point corresponding to the target video data can be obtained.
Step S507, calculating a time point difference value according to the audio playing time point and the video playing time point.
It can be understood that, after the audio playing time point and the video playing time point are obtained, a time point difference value can be calculated according to the audio playing time point and the video playing time point, and synchronous playing of the target audio data and the target video data can be realized according to the time point difference value.
Step S508, controlling the target video data and the target audio data to be played according to the time point difference.
It should be understood that the playing of the target video data and the target audio data may be controlled according to the time point difference value to achieve synchronous playing of the target video data and the target audio data.
It can be understood that a preset time point difference threshold value can be preset, the time point difference value is compared with the preset time point difference threshold value, and when the time point difference value is less than or equal to the preset time point difference threshold value, the playing is normally performed; when the time point difference is greater than the preset time point difference threshold, it is described that the sound and picture may be out of synchronization, and therefore, the target video data and the target audio data need to be adjusted and played after the adjustment is completed.
In the embodiment, the video data is stored in a video data decoding cache region, and the audio data is stored in an audio data decoding cache region; acquiring the audio data volume of the audio data cached in the audio data decoding cache region; judging whether the audio data volume is equal to a preset data volume threshold value or not; when the audio data volume is equal to the preset data volume threshold value, decoding the audio data cached in the audio data decoding cache region to obtain target audio data; decoding the video data cached in the video data decoding cache region to obtain target video data; acquiring an audio playing time point corresponding to the target audio data, and acquiring a video playing time point corresponding to the target video data; calculating a time point difference value according to the audio playing time point and the video playing time point; and controlling the target video data and the target audio data to be played according to the time point difference. And the target video data and the target audio data are controlled to be played through the time point difference value so as to realize synchronous playing of the target video data and the target audio data.
In an embodiment, as shown in fig. 6, a fifth embodiment of the video playing method based on streaming media of the present invention is proposed based on the first embodiment or the second embodiment, and in this embodiment, the description is made based on the first embodiment, and the step S20 includes:
step S201, searching for a video watching record corresponding to the target user.
It should be noted that, the manner of searching for the video watching record corresponding to the target user may be: and acquiring a history record corresponding to the current account information, and searching a video watching record corresponding to the target user from the history record.
It should be understood that when the video application is started and closed, and each video is started and closed, the face recognition can be performed to obtain the face information, so that the video watching records can be bound with the user. However, the history record corresponding to the current account information is the viewing record of all people, so that the video viewing record corresponding to the target user needs to be selected from the history record.
Step S202, determining the video information and closing time information of the video application when the video application is closed last time according to the video watching record.
It can be understood that when the video application is closed, the video being played is also closed, so that the video information and closing time information of the last closing time of the video application can be determined according to the video watching record, and the last playing video can be determined according to the video information.
Step S203, obtaining the current time information, and calculating the interval duration according to the current time information and the closing time information.
It should be noted that, the current time information is obtained, and the interval duration may be calculated according to the current time information and the closing time information.
In a specific implementation, for example, the current time may be determined to be 12 hours and 0 minutes in 5 months, 20 days and 2020 as the current time information, and the closing time may be determined to be 0 minutes in 8 hours in 5 months, 20 days and 2020 as the current closing time information, and the interval duration may be calculated to be 4 hours.
And step S204, judging whether the interval duration is less than a preset duration threshold.
It should be noted that, since the video that has not been seen last time is played for the user, it is necessary to consider timeliness, that is, it is necessary to determine whether the time that the user watched the video last time is the latest time period, and therefore, a preset time threshold is also preset, and whether to perform the subsequent steps is determined by comparing the interval time with the preset time threshold.
It should be understood that when the interval duration is greater than or equal to the preset duration threshold, which indicates that the video interval played last time is longer now, the user may have lost interest in this, and the video is not played any more, and the home interface of the video application is normally entered.
It is understood that the preset time threshold may be set by the user according to actual situations, and may be 12 hours, 24 hours, or other time durations, which is not limited in this embodiment.
Step S205, when the interval duration is smaller than the preset duration threshold, extracting a video name from the video information.
It should be understood that, when the interval duration is less than the preset duration threshold, it indicates that the time from the last playing of the video is not too long, and the user may have a requirement for continuous watching, and therefore, it is necessary to further determine that the video is played sufficiently, and therefore, the video duration and the video watching duration may be extracted from the video information, a duration difference value is calculated according to the video duration and the video watching duration, the duration difference value is compared with the preset difference threshold, and when the duration difference value is greater than the preset difference threshold, the video name is extracted from the video information.
It can be understood that, since a complete video has a leader and a trailer, and a user generally does not see the leader and the trailer when watching the video, the video duration in this embodiment is the duration obtained by subtracting the leader duration and the trailer duration from the total duration of the video. A preset difference threshold may be preset, and then a time length difference between the video time length and the video watching time length is calculated, and when the time length difference is greater than the preset difference threshold, it indicates that the user does not finish watching the video, where the preset difference threshold may be set by the user according to an actual situation, and this embodiment does not limit this.
And step S206, determining a target video according to the video name.
It should be appreciated that after the video name is obtained, the target video may be determined from the video name.
Further, after the step S50, the method further includes:
step S601, extracting video playing information from the video information.
It should be understood that after playing the video that the user did not see last time, it is also necessary to extract video playing information from the video information, and determine, according to the video playing information, from which node of the video the user needs to continue watching.
Step S602, a target video playing node is determined according to the video playing information, and a target audio playing node is determined according to the target video playing node.
It should be noted that the target video playing node may be determined according to the video playing information, for example, when the user sees the 25 th minute of the video at the last time of closing, the 25 th minute is taken as the target video playing node.
It can be understood that, since the video data and the audio data are played synchronously, after the target video playing node is determined, the target audio playing node can be determined accordingly according to the target video playing node.
Step S603, acquiring a current video playing node of the target video data and a current audio playing node of the target audio data.
It should be understood that, when the video is played, the video is generally played from the beginning, and therefore, the current video playing node of the target video data and the current audio playing node of the target audio data are both 0 th minute.
Step S604, adjusting the current video playing node according to the target video playing node, and adjusting the current audio playing node according to the target audio playing node.
It can be understood that, when the current video playing node and the current audio playing node are at 0 th minute and the target video playing node and the target audio playing node are at 25 th minute, the current video playing node is adjusted according to the target video playing node, and the current audio playing node is adjusted according to the target audio playing node.
It will be appreciated that in this way the video is played from the 25 th minute, and that this process is a very short process, so that it is possible to arrive at the time the user starts the video application, to see the last video that was not seen and then the last video to be viewed, for example, the user last seen the 25 th minute, this time to adjust to the 25 th minute of the video to be viewed.
In this embodiment, by searching for a video watching record corresponding to a target user, video information and closing time information when the video is closed last time are determined according to the video watching record, then the target video is determined, video playing information is extracted from the video information, then a playing node is determined, and the playing node is adjusted to play, so that when a user starts a video application, the user can see videos which are not watched last time, and then the videos of last time are watched, and the experience of watching the videos by the user is improved.
