Wherein the video playlist may be displayed in the form of a page in the screen, for example, referring to fig. 2b, a live page may be displayed in the screen, the live page includes the video playlist, and the current video playback may include video identification information (such as a name, a cover picture, and a main broadcast name) of video a, video b, video c, and video d.
202. When a display update operation for the video playlist is detected, the display of the video playlist in the screen is updated in accordance with the display update operation.
The display updating operation may be set according to actual requirements, and may include, for example, a dragging operation, a sliding operation, a clicking operation, a pressing operation, a shaking operation, and the like.
In an embodiment, updating the display of the video playlist in the screen may include: and displaying the undisplayed video identification information in the video playlist on a screen. For example, the step "updating the display of the video playlist in the screen according to the display update operation" may include:
determining target video identification information to be displayed from a video play list according to display updating operation;
target video identification information is displayed in the screen.
For example, the video identification information of the new video may be selected from the video playlist, that is, the video identification information to be displayed is determined from the non-displayed video identification information, and so on. The new video is a video that does not currently display identification information.
There are various ways to determine the target video identification information according to the display updating operation, for example, the target video identification information may be determined according to the operation parameters of the display updating operation, such as based on the operation distance, the operation duration, and the like. For example, when the operation is a drag operation, the operation may be determined based on parameters such as a drag distance, a drag duration, and an end position of the drag corresponding to the drag operation.
For example, the video playlist includes video identification information of video a, video b, video c, video d, video e, video f, and video g; referring to fig. 2b, video identification information of video a, video b, video c, video d is initially displayed in the screen; when the user performs a drag operation on the screen, such as dragging a page upwards, the terminal may determine that the video identification information of the videos e and f is displayed in the screen, and with reference to fig. 2c, display the video identification information of the videos e and f in the current screen. From the perspective of the user, the user can display the video information of the new video in the video playlist by dragging the page upwards.
In an embodiment, updating the display of the video playlist in the screen may include: and updating the video play list, and displaying the updated video play list in the screen.
For example, the video identification information of the new video may be acquired from the server, the current video playlist may be updated according to the video identification information of the new video, and the updated video playlist may be displayed on the screen.
For example, a video playlist includes video a, video b, video c, video d; referring to fig. 2b and 2d, the video identification information of video a, video b, video c, video d is initially displayed in the screen; when a user performs dragging operation on a screen, such as dragging a page downwards, the terminal can pull video identification information of a new video, such as video identification information of a video e, a video f, a video g and a video h, from the server; then, the current video playlist is updated, and at this time, the video playlist includes: video identification information of a video e, a video f, a video g and a video h; and displays the updated video playlist in the screen.
From the perspective of the user, the user can refresh the video information displayed on the screen by dragging the page downwards.
203. In the process of updating and displaying the video playlist, when a staying display event of the screen is detected, a video playing address corresponding to the target video identification information currently displayed on the screen is acquired.
For example, a video playing address corresponding to the target video identification information currently displayed on the screen may be acquired from the address server.
The stay display event is an event that the screen stays for a certain time to display the content in the process of updating and displaying the video playlist, for example, the time may be set according to actual requirements, for example, 2s and the like.
For example, in the process of updating the display of the video playlist, the screen stays for displaying for 2s for the current video identification information, and then a stay display event is triggered.
The address server may provide a video playing address, for example, a redirect server 16 in a live system, referring to the live system shown in fig. 1 b.
The video playing address may be a video playing URL (Uniform Resource Locator), and for example, may include a CDN server address.
For example, referring to fig. 2c, when the user drags the video playlist upward multiple times (i.e., the user drags the playlist upward multiple times), the terminal updates the video identification information in the displayed video playlist in the screen multiple times based on the dragging operation, and assuming that the user stops the dragging operation when the video identification information of the video e and f is displayed on the screen, the user continues the dragging operation after the screen is displayed for 2s (second), at this time, the terminal detects the stop display event, and the terminal may obtain the video playing addresses of the videos a, b, e, and f from the address server.
For another example, referring to fig. 2d, when the user drags the video playlist downwards for multiple times, the terminal may continuously update and display the video playlist (that is, the user drags the video playlist downwards for multiple times), assuming that the user stops dragging operation when the video identifier information of the video e, the video f, the video g, and the video h is displayed on the screen, and the user continues dragging operation after the screen is displayed for 2 seconds, at this time, the terminal detects a stop display event, and the terminal may obtain the video identifier information of the video e, the video f, the video g, and the video h from the address server.
In an embodiment, in order to improve the identification of the video of interest of the user more accurately and save resources, a preset duration is set, and when the stay display duration corresponding to the stay display event is longer than the preset duration, it is considered that the user is interested in the currently displayed video information, and a subsequent user may play the video, so that a play address of the video needs to be loaded in advance.
Specifically, the step of "acquiring a video playing address corresponding to the target video identification information currently displayed on the screen" may include:
acquiring a stay display duration corresponding to the stay display event;
and when the stay time is longer than the preset time, acquiring a video playing address corresponding to the target video identification information currently displayed in the screen.
The preset duration may be set according to an actual requirement, or may be set according to behavior feature information of a user playing a video, for example, 5 s.
For example, referring to fig. 2c, when the user drags the video playlist upward for multiple times (i.e., the user drags the playlist upward for multiple times), the terminal updates the video identifier information in the displayed video playlist in the screen based on the dragging operation for multiple times, assuming that the user stops the dragging operation when the video identifier information of the video e and f is displayed on the screen, the user continues the dragging operation after the screen is displayed for 6s, at this time, the terminal detects the stay display event, and determines that the stay display duration 6s is greater than the preset duration 5s, at this time, the terminal may obtain the video playing addresses of the videos a, b, e, and f from the address server.
204. And when the video corresponding to the target video identification information needs to be played, playing the video according to the obtained video playing address.
For example, in an embodiment, when a play instruction corresponding to the target video identification information is received, that is, a video corresponding to the target video identification information needs to be played is determined, and at this time, video playing can be performed according to the obtained video playing address.
The target video identification information can also comprise a video playing link of the target video; at this time, a corresponding play instruction may be triggered based on a triggering operation (e.g., a click operation) for the video play link.
The video playing address may be a video playing URL (Uniform Resource Locator), and for example, may include a CDN server address.
For example, the video data may be downloaded from the corresponding CDN server according to a video playing address obtained in advance, and the downloaded video data may be decoded and played.
The video playing scheme provided by the embodiment of the invention can acquire the video playing address of the video in advance, and then directly acquire video data according to the video playing address acquired in advance for playing when the video is played; compared with the traditional video playing scheme, the scheme can save the time consumed by loading the video playing address, reduce the time consumed by loading the video playing, and improve the starting speed of the video live broadcast.
For example, taking the live broadcast system shown in fig. 1a as an example, by using the method of the embodiment of the present invention, the terminal 10 may display a video playlist on the screen, where the video playlist includes at least one piece of video identification information; updating the display of the video playlist in the screen according to the display update operation when the display update operation for the video playlist is detected; in the process of updating and displaying the video playlist, when a staying display event of a screen is detected, a video playing address corresponding to target video identification information currently displayed on the screen is obtained from the address server 20 in advance; when a video corresponding to the target video identification information needs to be played, audio and video data is obtained from the data server 40 according to a video playing address obtained in advance for playing the video. Compared with the traditional video playing scheme, the video playing scheme adopted by the terminal 10 in the live broadcast system can save the loading time of the video playing address, reduce the loading time of the video playing and improve the starting speed of the video live broadcast.
For example, taking the live broadcast system shown in fig. 1b as an example, by using the method in the embodiment of the present invention, the playing terminal 15 may display a video playlist on the screen, where the video playlist includes at least one piece of video identification information; updating the display of the video playlist in the screen according to the display update operation when the display update operation for the video playlist is detected; in the process of updating and displaying the video playlist, when a staying display event of the screen is detected, a video playing address, namely a CDN address, corresponding to target video identification information currently displayed on the screen is obtained from the redirection server 16 in advance; when a video corresponding to the target video identification information needs to be played, audio and video data is acquired from the CDN server 14 according to a video playing address acquired in advance for playing. Compared with the traditional video playing scheme, the video playing scheme adopted by the playing terminal 15 in the live broadcasting system can save the loading time of the video playing address, reduce the loading time of the video playing and improve the starting speed of the video live broadcasting.
Referring to fig. 3a, for a conventional video playing scheme, when a user clicks to play a video, a player on a terminal needs to access a redirection server to obtain a video playing address, and then the player follows the video playing address to play the video, where an average time consumed for the player to access the redirection server to obtain the address is 400ms, a time consumed for loading the video playing is large, and a starting speed is slow.
Referring to fig. 3b, in the video playing scheme provided by the embodiment of the present invention, in the process of dragging the video playlist by the user, if a stop display event is detected, the video playing address of the video is obtained in advance, and when the user clicks and plays the video at the obtained video playing address, the player can directly play the video according to the video playing address obtained in advance, so that a process of accessing the redirection server to obtain the address is omitted, time consumed for loading the video playing address is saved, time consumed for loading the video playing is reduced, and the start speed of live video broadcast is increased.
In an embodiment, in order to improve the fluency and quality of video playing, a playing preparation process may be performed on the video data first, when the preparation process is completed, the video data is downloaded according to a video playing address obtained in advance, and the downloaded video data is played according to video playing parameter information obtained by the playing preparation process.
For example, referring to fig. 4a, a flow for playing a video is loaded for a player. Specifically, the player SDK sends a preparation parsing instruction (prepareAsync) to the playback kernel, the playback kernel sends the instruction to a preparation parsing Thread (preparethread), and the playback preparation parsing Thread (preparethread) calls openFile to perform playback preparation processing according to the instruction, for example, findstreamlnfo is executed to parse video data to obtain video playback parameter information.
For example, the analysis preparation thread may call openFile to download audio and video data (preload) to be analyzed, separate the downloaded audio and video data through a fft Demuxer to obtain video data and audio data, and then analyze the video data and the audio data.
When the analysis of the video data is completed, returning a preparation completion notification message (such as onPreppred) to the player SDK, calling Start by the player SDK to Start a downloading Thread (such as a read packet Thread ReadPacket Thread), downloading the video data according to a video playing address through the downloading Thread, and decoding and playing the downloaded video data through a video decoding Thread (such as a video DeodeThread and an Audio DeodeThread).
As can be seen from the flow shown in fig. 4a for loading and playing video, since the data downloading thread, such as the reading package thread, must be started after the audio and video data analysis is completed, i.e., the playing preparation process is completed, however, the audio and video data analysis needs to spend more real scenes, which results in that the data downloading thread is started later, such as the reading package thread, the loading time of video playing is increased, and the starting speed of video playing is reduced.
In an embodiment, the data downloading thread may be started, for example, the read packet thread downloads the audio/video data to be played, while the play preparation processing is performed. That is, the step "performing video playing according to the video playing address obtained in advance" may include:
carrying out playing preparation processing according to a video playing address acquired in advance, and simultaneously downloading audio and video data to be played from a data server;
and when the playing preparation processing is finished, playing the downloaded audio and video data.
For example, a play ready analysis Thread (prepare Thread) is started, and a data download Thread (e.g., a read packet Thread ReadPacket Thread) is started at the same time; performing play preparation processing according to a video play address acquired in advance through a play preparation analysis Thread (prepare Thread); downloading audio and video data to be played from a data server through a data downloading Thread (such as a read packet Thread) according to a video playing address
For example, referring to fig. 4b, a play preparation Thread (e.g., prepare Thread) may be started to call OpenFile and simultaneously start a packet reading Thread, so as to avoid that the packet reading Thread is started to download data after findStramInfo and oncompressed are needed in a conventional flow, reduce data downloading time, reduce time consumed for loading video, and thus improve video starting speed. Through practical tests, the time consumption of about 200ms can be saved by adopting the scheme to optimize the playing process.
The process of the playing preparation processing may include a process of obtaining sample audio/video data according to the video playing address, and analyzing the sample audio/video data to obtain video playing parameter information. That is, the step of "performing play preparation processing according to a video play address acquired in advance, and downloading audio/video data to be played from the data server at the same time" may include:
downloading sample audio and video data from a data server according to the video playing address, analyzing the downloaded sample audio and video data, and downloading audio and video data to be played from the data server;
when the data analysis is successful, determining that the playing preparation processing is completed;
the step of playing the downloaded audio/video data when the play preparation process is completed may include:
and when the playing preparation processing is finished, playing the downloaded audio and video data according to the video playing parameter information obtained by analysis.
The sample audio/video data can be selected from the audio/video data of the video to be played according to actual requirements, for example, the sample audio/video data can be audio/video data of a certain time length in front of the video, and the like. E.g. audiovisual data of the first few seconds of video, etc.
The video playing parameter information may include: resolution of video, frame rate, audio playback parameters, etc.
In an embodiment, when the data analysis is successful, the downloading of the sample audio/video data may also be stopped.
In one embodiment, when the data analysis fails, the sample audio/video data can be downloaded continuously with the video playing address.
For example, referring to fig. 4b, after the play ready analysis Thread (e.g., prepare Thread) is started, the play ready analysis Thread calls OpenFile implementation: downloading sample audio and video data from a corresponding CDN server according to the video playing address, and then analyzing the downloaded sample audio and video data; when the data analysis is successful, it is determined that the playback preparation process is completed, and preparation completion notification information (e.g., onPreppred) is returned to the player SDK. After receiving the preparation completion notification information (e.g., onPreppred), the player SDK starts a video/audio decoding thread (e.g., VideoDeodeThread, Audio DeodeThread) to decode the downloaded audio/video data, and plays the decoded data according to the video playing parameter information obtained by the playing preparation processing.
As can be seen from the above description, the playback preparation process is required before playing back the video, and the data needs to be downloaded for analysis during the playback preparation process. The large amount of data analyzed in the process of preparing the playing process can lead to long loading time, and the starting speed of video playing is reduced.
In order to reduce the loading time and increase the starting speed of video playing, in an embodiment, the data volume analyzed in the playing preparation process can also be reduced. For example, the step "analyzing the downloaded sample audio/video data" may include:
analyzing the currently downloaded sample audio/video data;
when the data analysis fails, acquiring the accumulated frame number of the currently analyzed sample video data;
judging whether the accumulated frame number is greater than a preset frame number or not; if so, determining that the playing preparation processing is finished.
In an embodiment, when the accumulated frame number is greater than the preset frame number, the downloading of the sample audio/video data may also be stopped.
The preset frame number may be obtained according to an actual test, for example, may be 5 frames.
For example, referring to fig. 4b, after a play preparation analysis Thread (e.g., prepare Thread) is started, the play preparation analysis Thread invokes OpenFile to download sample audio/video data from a corresponding CDN server according to a video play address, analyzes the downloaded sample audio/video data, determines that the play preparation process is completed when the analysis is successful, acquires the number of frames of video data currently analyzed accumulatively when the analysis is failed, stops downloading the sample audio/video data when the number of frames is greater than a preset number of frames (e.g., 5 frames), and returns preparation completion notification information (e.g., onprepped) to the player SDK.
Therefore, the embodiment of the invention can reduce the analyzed data volume, greatly reduce the actual data downloading, reduce the loading time consumption of video playing and greatly improve the starting speed of video playing. The reduced analyzed data volume optimization may optimize the loading time of approximately 700 ms.
As can be seen from the above, the embodiment of the present invention displays the video playlist on the screen, where the video playlist includes video identification information of at least one video; updating the display of the video playlist in the screen according to the display update operation when the display update operation for the video playlist is detected; in the process of updating and displaying a video playlist, when a staying display event of a screen is detected, a video playing address corresponding to target video identification information currently displayed on the screen is acquired; and when the video corresponding to the target video identification information needs to be played, playing the video according to the video playing address acquired in advance. The scheme can acquire the playing address of the video in advance before the video is played, and the video can be played directly according to the pre-acquired playing address when the video is played subsequently; therefore, the time consumed by loading the video playing can be reduced, and the starting speed of the video live broadcast is improved.
The embodiment of the invention can also optimize the playing flow of the playing end, trigger the downloading of the audio and video data while performing the playing preparation processing, reduce the time consumption for downloading the data, further reduce the time consumption for loading the video playing, and improve the starting speed of the live video.
In addition, the embodiment of the invention can also reduce the number of analysis in the playing preparation processing, further reduce the time consumption for loading the video playing and greatly improve the starting speed of the video live broadcast.
The method described in the above embodiments is further illustrated in detail by way of example.
In an embodiment, the video playing method of the present invention will be described in detail by taking an example in which a video playing device is integrated in a terminal.
As shown in fig. 5a, the specific flow of the video playing method may be as follows:
501. the terminal displays a video play list on a screen, wherein the video play list comprises video identification information of at least one video.
Wherein the video playlist may include video identification information for one or more videos. The video identification information may include: the name of the video, cover information for the video (e.g., cover pictures), anchor information (e.g., anchor name, etc.), and so forth.
Wherein the video playlist may be displayed in the form of a page in the screen, for example, referring to fig. 2b, a live page may be displayed in the screen, the live page includes the video playlist, and the current video playback may include video identification information (such as a name, a cover picture, and a main broadcast name) of video a, video b, video c, and video d.
502. When the display updating operation aiming at the video playlist is detected, the terminal updates the display of the video playlist in the screen according to the display updating operation.
The display updating operation may be set according to actual requirements, and may include, for example, a dragging operation, a sliding operation, a clicking operation, a pressing operation, a shaking operation, and the like.
In an embodiment, updating the display of the video playlist in the screen may include: and displaying the undisplayed video identification information in the video playlist on a screen. For example, the terminal determines the identification information of the target video to be displayed from the video play list according to the display updating operation; displaying determined video identification information in a screen
For example, the video playlist includes video identification information of video a, video b, video c, video d, video e, video f, and video g; referring to fig. 2b, video identification information of video a, video b, video c, video d is initially displayed in the screen; when the user performs a drag operation on the screen, such as dragging a page upwards, the terminal may determine that the video identification information of the videos e and f is displayed in the screen, and with reference to fig. 2c, display the video identification information of the videos e and f in the current screen. From the perspective of the user, the user can display the video information of the new video in the video playlist by dragging the page upwards.
503. In the process of updating and displaying the video playlist, when a staying display event of a screen is detected, the terminal acquires a video playing address corresponding to the target video identification information currently displayed on the screen from the redirection server in advance.
The stay display event is an event that the screen stays for a certain time to display the content in the process of updating and displaying the video playlist, for example, the time may be set according to actual requirements, for example, 2s and the like.
For example, in the process of updating the display of the video playlist, the screen stays for displaying for 2s for the current video identification information, and then a stay display event is triggered.
The video playing address may be a video playing URL (Uniform Resource Locator), and for example, may include a CDN server address.
For example, referring to fig. 2c, when the user drags the video playlist upward multiple times (i.e., the user drags the playlist upward multiple times), the terminal updates the video identification information in the displayed video playlist in the screen multiple times based on the dragging operation, and assuming that the user stops the dragging operation when the video identification information of the video e and f is displayed on the screen, the user continues the dragging operation after the screen is displayed for 2s, at this time, the terminal detects a stay display event, and the terminal may obtain the video playing addresses of the videos a, b, e, and f from the address server.
In an embodiment, in order to improve the identification of the video of interest of the user more accurately and save resources, a preset duration is set, and when the stay display duration corresponding to the stay display event is longer than the preset duration, it is considered that the user is interested in the currently displayed video information, and the subsequent user may play the video. For example, the terminal acquires a stay display duration corresponding to a stay display event; and when the stay time is longer than the preset time, acquiring a video playing address corresponding to the target video identification information displayed in the screen from the address server in advance.
The preset duration may be set according to an actual requirement, or may be set according to behavior feature information of a user playing a video, for example, 5 s.
504. When a video corresponding to the target video identification information needs to be played, the terminal performs playing preparation processing according to a video playing address acquired in advance, and simultaneously downloads audio and video data to be played from the CDN server.
The process of the playing preparation processing may include a process of obtaining sample audio/video data according to the video playing address, and analyzing the sample audio/video data to obtain video playing parameter information.
The video playing parameter information may include: resolution of video, frame rate, audio playback parameters, etc.
For example, sample audio and video data is downloaded from a corresponding CDN server according to a video playing address, and the downloaded sample audio and video data is analyzed;
when the analysis is successful, determining that the playing preparation processing is completed, and stopping downloading the sample audio and video data;
and when the analysis fails, continuing to download the sample audio and video data, and stopping downloading the analyzed audio and video data until the analysis is successful or a preset termination condition is met.
For example, referring to fig. 4b, after the play ready analysis Thread (e.g., prepare Thread) is started, the play ready analysis Thread calls OpenFile implementation: downloading sample audio and video data from a corresponding CDN server according to the video playing address, and then analyzing the downloaded sample audio and video data; when the data analysis is successful, it is determined that the playback preparation process is completed, and preparation completion notification information (e.g., onPreppred) is returned to the player SDK. After receiving the preparation completion notification information (e.g., onPreppred), the player SDK starts a video/audio decoding thread (e.g., VideoDeodeThread, Audio DeodeThread) to decode the downloaded audio/video data, and plays the decoded data according to the video playing parameter information obtained by the playing preparation processing.
In an embodiment, in order to reduce the analysis data amount and reduce the loading time of video playing, the cumulative frame number of the currently analyzed sample video data can be obtained when the current audio/video data is failed to be analyzed; judging whether the accumulated frame number is greater than a preset frame number or not; if so, determining that the playing preparation processing is finished, and stopping data downloading analysis.
For example, referring to fig. 4b, after a play preparation analysis Thread (e.g., prepare Thread) is started, the play preparation analysis Thread invokes OpenFile to download sample audio/video data from a corresponding CDN server according to a video play address, analyzes the downloaded sample audio/video data, determines that the play preparation process is completed when the analysis is successful, acquires the number of frames of video data currently analyzed accumulatively when the analysis is failed, stops downloading the sample audio/video data when the number of frames is greater than a preset number of frames (e.g., 5 frames), and returns preparation completion notification information (e.g., onprepped) to the player SDK.
505. And when the playing preparation processing is finished, playing the downloaded audio and video data.
In an embodiment, when the sample audio/video data is successfully analyzed, the downloaded audio/video data can be played according to the video playing parameter information obtained by the playing preparation processing.
For example, when the playback preparation process is completed, the downloaded audio/video data may be decoded, and the decoded data may be played according to the video playback parameter information.
For example, referring to fig. 4b, when receiving the preparation completion notification information (e.g., onprepped), the player SDK starts a video/audio decoding thread (e.g., videodeodeodethread, audiodeodeodethread) to decode the downloaded video/audio data, and plays the decoded data.
As can be seen from the above, the video playing method provided in the embodiment of the present invention can obtain the playing address of the video in advance before the video is played, and can directly play the video according to the obtained playing address when the video is played again; therefore, the time consumed by loading the video playing can be reduced, and compared with the traditional playing scheme, the starting speed of the video live broadcast can be increased.
The embodiment of the invention can also optimize the playing flow of the playing end, trigger the downloading of the audio and video data while performing the playing preparation processing, reduce the time consumption for downloading the data, further reduce the time consumption for loading the video playing, and improve the starting speed of the live video.
In addition, the embodiment of the invention can also reduce the number of analysis in the playing preparation processing, further reduce the time consumption for loading the video playing and greatly improve the starting speed of the video live broadcast.
Through practical tests, the video playing scheme provided by the embodiment of the invention can enable the playing end to averagely reduce the loading time consumption by about 1.1S, wherein the CDN address is preloaded for about 200ms (millisecond ), the playing flow is optimized for about 200ms, and the analysis data size is optimized for about 700ms of loading time consumption. Referring to fig. 5b, compared with the conventional playing scheme, live video broadcasting can be started quickly, in fig. 5b, for the same video, the video is still loaded when the video is live broadcast by the conventional playing scheme (refer to the left diagram in fig. 5 b), but the video playing scheme provided by the embodiment of the present invention is used to start playing the video.
