Detailed Description
For the description content in the background art section, in the live broadcast process, the live broadcast streaming end transmits VIDEO data to the streaming media center node through an RTMP (Real Time Messaging Protocol), and the VIDEO data may adopt an FLV (FLASH VIDEO) streaming media format. After a video recording function is started aiming at live broadcast content, recording scripts store recorded streaming media data into video files in a streaming copying mode, and after the live broadcast is finished, the recorded video files are FLV format files.
Wherein the video-on-demand format is usually MP4 format. Therefore, after the live broadcast is finished, the recorded video file generally needs to be re-encoded, the FLV format video file is transcoded into the MP4 format video file, and then the MP4 format video file is encoded to generate a new video file, so that the ratio of the video transcoding time length to the live broadcast video time length is a one-to-one relationship, the recorded video file time length determines the time length spent for generating the live broadcast playback file, the live broadcast playback file can be generated after the live broadcast is finished, and a user cannot timely play back and watch the target content in the live broadcast process.
In order to solve the above problems, it is proposed to repackage a file header of a recorded video file after a live broadcast technology, then divide the file into a plurality of fragmented files, and push the fragmented files to a storage device (e.g., a cloud storage server, which may be distributed to each terminal through a CDN (Content Delivery Network) server, etc.), so as to develop the file for a user to watch. Since it takes a relatively short time, e.g. 3-4 minutes, to repackage the headers, the user can play back the live content as soon as possible. However, once the header encapsulation of the recorded video file fails, transcoding processing needs to be performed according to the above-described method to ensure the consistency of the format of the video file in the later period, and thus, the live playback processing method based on the header encapsulation processing method is poor in reliability.
In order to further solve the problems and improve the efficiency and reliability of live broadcast playback processing, the method and the device can be used for transcoding the recorded video file in the live broadcast content recording process, so that the live broadcast playback file can be generated after live broadcast is finished, and a user can play back and watch live broadcast content in time. Specifically, in the live broadcasting process, the live broadcasting content can be recorded in a slicing mode according to a preset recording rule to obtain continuous video slicing files, in the slicing recording process, the obtained video slicing files are pushed to transcoding equipment (such as a transcoding server) to be transcoded, therefore, when the live broadcasting is finished, only the last video slicing file is pushed to the transcoding equipment to be transcoded, and the time of waiting for transcoding by a user is greatly shortened compared with the whole video file.
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it should be understood that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, a schematic diagram of a system architecture of an optional application environment suitable for the live playback processing method provided in the present application is shown, where the system architecture may include a plurality of terminals 110, a live server 120, a transcoding device 130, and a storage device 140, where:

As such, the terminal 110 may include, but is not limited to, a smart phone, a tablet, a wearable device, a netbook, an Augmented Reality (AR) device, a Virtual Reality (VR) device, a vehicle-mounted device, a desktop computer, and the like. The electronic device shown in fig. 1 is only an example, and should not bring any limitation to the functions and the scope of use of the embodiments of the present application. Under different application scenarios, users with different identities can select the same or different terminals to realize live broadcast playback, and the application is not limited to this.
The live broadcast server 120 can support the service equipment of the live broadcast service, and can obtain live broadcast stream information containing live broadcast content generated by a terminal in the live broadcast process of the anchor, and push the live broadcast stream information to the terminal of each audience currently watching the live broadcast of the anchor to play so that each audience entering a live broadcast room of the anchor can synchronously watch the live broadcast content of the anchor.
In the embodiment of the application, in order to be able to play back live content after live broadcasting is finished, a live broadcasting server can configure a live broadcasting recording function, live broadcasting stream information sent by a live broadcasting terminal used by a main broadcast can be copied, a video file containing synchronous live broadcasting content is recorded, the video file is usually a flv format video file, then the live broadcasting stream information is pushed to transcoding equipment for transcoding processing, the implementation method of video recording of the live broadcasting content of each main broadcast by the live broadcasting server is not limited, corresponding live broadcasting identification can be configured in order to distinguish the live broadcasting content of each main broadcast, such as main broadcast account numbers and live broadcasting themes, the content of the unique live broadcasting identification is not limited by the application.
Optionally, in practical applications, because the live content of the anchor is live stream information acquired by a terminal (such as at least one live device with an audio and video acquisition function) used by the anchor, the live stream information is pushed to a live server, and the live stream information can also be fragmented and copied by the terminal, after a video fragment file containing part of the live content is obtained, the live stream information is pushed to a transcoding device directly or through the live server to be transcoded, and the like.
The transcoding device 130 may be a transcoding server, which supports a video transcoding technology, that is, converts a video code stream that has been compressed and encoded into another video code stream, for example, converts an FLV streaming media format into an MP4 format, so as to adapt to different network bandwidths, different terminal processing capabilities, and different user requirements, and the product type and the transcoding operation process of the transcoding device 130 are not described in detail in this application.
It should be understood that, in practical applications, on any live broadcast platform, a plurality of anchor broadcasts are generally live broadcast, if a plurality of live broadcast contents need to be recorded respectively, the live broadcast playback processing method provided by the present application is executed, a video fragment file for live broadcast contents of different anchor broadcasts is pushed to a transcoding device in real time, at this time, the video fragment file needs to carry a corresponding live broadcast identifier, so that all video fragment files of the same live broadcast content can be identified according to the live broadcast identifier in the following process, and the implementation process is not described in detail in the present application.
The storage device 140 may be a cloud storage server, and is configured to store a live playback file after successful transcoding, and may be multiple live playback fragment files for the same live content, or a complete live playback file obtained by splicing the multiple live playback fragment files end to end according to a recording time sequence, so that after live playback is finished, the live playback file that has been successfully transcoded is opened to a user. For example, a user may use a terminal to send a live playback request carrying a live content identifier to the storage device 140, pull a live playback file corresponding to the live content identifier in the storage device 140, and play back corresponding live content.
In practical applications, the storage device 140 may be an independent device node, or may be a cluster formed by multiple device nodes, such as a content distribution network with various structures, so as to meet content distribution requirements in various scenarios.
Optionally, the transcoding device and the storage device may be integrated in a live server providing live broadcast service, so that the live server may provide not only live broadcast service but also live broadcast playback service, and has processing functions of transcoding, distributing, and the like of a recorded video file.
It should be understood that the system architecture shown in fig. 1 does not constitute a limitation to the system architecture of the application environment in the embodiment of the present application, and in practical applications, the system may include more devices than those shown in fig. 1, which is not listed here.
Referring to fig. 2, a schematic flow diagram of an optional example one of a live playback processing method provided by the present application is shown, where the method may be applied to a computer device, where the computer device may be a live streaming server or a terminal used by an anchor broadcast for live broadcast, and in order to quickly obtain a live playback file after the end of live broadcast in a scene where the anchor broadcast uses the terminal for live broadcast, a generated live content needs to be recorded and transcoded into a video file in a playable format, for which the present application provides a live playback processing method shown in fig. 2, where the method may include:
step S21, obtaining a video recording instruction aiming at live broadcast content;
step S22, responding to the video recording instruction, and performing fragment recording on the live broadcast content according to a preset recording rule to obtain a corresponding video fragment file;
and S23, in the fragment recording process, pushing each obtained video fragment file to transcoding equipment, and transcoding the video fragment file by the transcoding equipment to obtain a live playback file of live content.
In the process that a user uses a terminal to carry out live broadcasting, if live broadcasting content needs to be recorded, the user or other users can watch the live broadcasting content after the live broadcasting is finished, a live broadcasting recording function on a live broadcasting interface can be triggered, or a screen recording function of the terminal is triggered, a video recording instruction for the current live broadcasting content is generated, a video recording function for the current live broadcasting content is triggered, and if the generated live broadcasting stream information (such as the terminal carries out audio and video acquisition on a main broadcast and generates), the generated video file is obtained by directly copying.
In order to fully utilize resources of computer equipment and reduce waiting time of a user watching live playback video, the method and the device adopt a fragment recording mode in a video recording process of responding to current live content, so that the video fragment file recorded before can be transcoded while recording subsequent live content, namely, the recorded video file is transcoded while recording the live content to obtain an MP4 format video file, the recorded complete video file is transcoded without waiting for the end of recording the live content, and therefore, after the live content is played, the user who wants to play back the live content to watch can obtain the live playback file without waiting for the live time.
Based on this, when the live content is recorded, the live content can be recorded in fragments according to preset recording rules configured in advance for the live content, or default preset recording rules and the like, so that a video file of the whole live content is divided into a plurality of video fragments, each video fragment file is obtained through recording, the video fragment files can be timely pushed to transcoding equipment to be transcoded, the live playback fragment files of the part of live content are obtained, and the last video fragment file is pushed to the transcoding equipment until live broadcasting is finished.
Based on this, if a certain user needs to play back live content immediately after live broadcasting is finished, according to the live broadcast playback processing method provided by the application, a complete live broadcast playback file can be obtained only by waiting for a short time. Of course, if the start time of playback selected by the user is earlier, that is, the user is located in the successfully transcoded live playback segment file, the live playback segment file corresponding to the start time can also be directly pulled to play, and playback of live content can be started without waiting for successful transcoding of all recorded video segment files.
In addition, because the method transcodes the recorded video segment file in the live broadcast process to obtain the video file which can be directly played back, namely the live broadcast playback segment file, before the live broadcast is finished, the historical live broadcast content, namely the live broadcast content before the playback can be selected to be watched, under the condition, at least a certain release starting time can be selected to be watched according to the method described above, the corresponding live broadcast playback segment file is pulled to be played accordingly, the corresponding historical live broadcast content is watched, and the watching requirements of users on the live broadcast content of different nodes are met.
Referring to fig. 3, a flowchart of an optional example two of the live playback processing method provided in the present application is schematically shown, where the method may be an optional detailed implementation method of the live playback processing method provided above, for example, an implementation process of implementing fragment recording of current live content based on an optional content of the preset recording rule is described, and as shown in fig. 3, the method may include:
step S31, obtaining a video recording instruction aiming at live broadcast content;
step S32, responding to the video recording instruction, and obtaining the fragment recording duration aiming at the live content;
step S33, in the live broadcast process, according to the fragment recording time length, performing fragment recording on the live broadcast content to obtain a continuous video fragment file with the fragment recording time length;
in the embodiment of the application, the whole video file of the live content can be divided according to a certain time length to generate a continuous video fragment file. For the time length, the anchor is known with the live broadcast content and the live broadcast time length thereof, so that the anchor can flexibly configure the live broadcast content to be live broadcast to obtain the corresponding fragment recording time length. Optionally, in combination with the above description of the preset recording rule, the fragment recording time length may also be a default time length, and the configuration mode and the value of the fragment recording time length are not limited in the present application.
Based on the above analysis, in this embodiment, timing may be started from responding to a video recording instruction, that is, timing is started from video recording of live content (for example, copying live stream information generated by a live terminal), the timing time reaches a fragment recording duration, a video file recorded in the time period is used as a video fragment file, and then, according to this manner, a video fragment file recorded in a next fragment recording duration may be obtained, and these video fragment files may be sequentially recorded as 001.flv, 002.flv, 003.flv, and the like, so that a plurality of video fragment files with continuous recording time may be obtained, and a complete recording file of the live content may be formed.
In still other embodiments, after the segment recording duration is obtained, the whole live content may also be divided into a plurality of time segments according to the live content duration recorded in advance for the live content, and the time of the division point is recorded, so that in the process of synchronously recording the live content, whether the current live time reaches the time of any division point is detected, and thus a video segment file and the like are formed by the live stream recorded between two adjacent division point times.
Step S34, in the fragment recording process, pushing each obtained video fragment file to transcoding equipment for real-time transcoding processing to obtain a corresponding live broadcast playback fragment file;
as described above in relation to the technical solution of the present application, each video segment file obtained by recording can be directly pushed to a transcoding device to perform real-time transcoding processing, so as to obtain a corresponding live playback segment file, thus, live content is recorded in real time while anchor live, and meanwhile, the video segment file obtained by recording segments is pushed to the transcoding device to perform real-time transcoding processing, that is, in a live broadcasting process, live content that has been live can be recorded and transcoded into a live playback file in a video stream format that can be played back, after the live broadcasting is finished, there is no need to wait for the live broadcasting time, and a complete live playback file can be obtained quickly.
Illustratively, a live broadcast is started at a main broadcast using terminal, a live broadcast stream is pushed successfully, a recorded live broadcast stream script can be started at the same time, a video file (such as copied live broadcast stream information) is cut and recorded according to the time length of 5 minutes, a video fragment file with the time length of 5 minutes is generated, then a video fragment file to be recorded later is not needed, the video fragment file to be recorded next 5 minutes can be directly pushed to transcoding equipment for transcoding processing, the video fragment file to be transcoded successfully can be stored in storage equipment such as a cloud storage server, and the video fragment file can also be pushed to a Content Distribution Network (CDN) for a user to watch live broadcast playback video.
And step S35, determining to push the obtained last video fragment file to the transcoding device, and sending a live broadcast ending notification to the storage device, so that the storage device can push a live broadcast playback file aiming at the live broadcast content.
In order to ensure the integrity of live playback video, after receiving a plurality of video fragment files aiming at the same live content, if receiving a second video fragment file of the live content, the transcoding device can splice the video contents of the plurality of video fragment files end to end according to the morning and evening sequence of recording time/transcoding push time, that is, the starting recording position of the video fragment file of the later received live content is spliced to the tail position of the video fragment file of the live content received earlier (the application refers to the adjacent receiving), the processing is advanced, after the terminal pushes the generated last video fragment file to the transcoding device for transcoding after the live content is finished, the transcoding device can splice the last video fragment file to the tail position of the live playback file spliced before, the video playback file of the complete live playback video can be obtained, and the detailed description of the process is omitted.
Optionally, after transcoding each video segment file successfully according to the transcoding processing method described above, the transcoding device may send the video segment file to a storage device (such as a cloud storage server) for storage, for example, a list mode is adopted, and a plurality of live playback files for each live content are recorded according to a recording time sequence, so that a corresponding live playback video is subsequently pulled and played. Or, the transcoding device may also send the live playback file of each live content after the splicing processing to the storage device for storage, and the storage implementation manner of the live playback segment file/live playback file is not limited in this application.
In addition, after determining that the live broadcast of a certain live broadcast room for video recording is finished, and sending the corresponding last video fragment file to the transcoding device, a corresponding live broadcast finish notification can be sent to the storage device, so that after receiving the live broadcast finish notification, the storage device can push a live broadcast playback file for live broadcast content of the live broadcast room, such as a plurality of live broadcast playback fragment files, or after determining that the complete video of the live broadcast content is received (such as whether the complete video is determined by comparing live broadcast time with recording time, and the like), push the live broadcast playback file, specifically, push of the live broadcast playback file can be realized through a content distribution network, and details are not given in the implementation process.
Based on the above analysis, for the live broadcast room in which the video recording function is started in the live broadcast process, live broadcast recording prompt information/playback watching prompt information, such as preset prompt icons or text descriptions, can be output on a live broadcast interface, and after the live broadcast is finished, a live broadcast playback file of live broadcast content is quickly obtained according to the above-described method, and then the output state of corresponding prompt information is adjusted to show that the finished live broadcast content of the current live broadcast room can be played back and watched, and a user can trigger watching of a live broadcast playback video, but not limited to this implementation manner of prompting watching of playback live broadcast content.
Optionally, in order to improve the viewing times of the live content, the anchor broadcast may also perform video recording on the live content according to, but not limited to, the method described above, and at the same time, quickly convert the recorded video file into a live playback file that can be played, after the live broadcast is finished, the content distribution network may push the live playback file of each live content to a live account of the corresponding anchor broadcast in time, and output a prompt message indicating that the live content can be played back at a live address corresponding to the live account, so that the user may directly click and view the recorded live content without waiting for transcoding; certainly, the audience can also set that the live playback video is watched after the live broadcast is finished, so that the corresponding live playback file can be quickly obtained according to the method for playing after the corresponding anchor live broadcast is finished, and the user experience is improved.
Referring to fig. 4, a flowchart of an optional example three of the live playback processing method provided in the present application is schematically shown, where the method may be applied to a transcoding device, such as the above-mentioned transcoding server, and as shown in fig. 4, a live playback processing method executed by the transcoding device may include:
step S41, any video slicing file aiming at live content is obtained; the video fragment file is pushed after the live content is subjected to fragment recording according to a preset recording rule in the live broadcasting process;
in the live broadcast playback processing method described above in connection with the computer device side, in the live broadcast process of any anchor, after the recording function of live broadcast content is started, the live broadcast stream information in the live broadcast room is copied in a fragment recording manner, and each time a video fragment file is obtained by copying, the live broadcast stream information can be pushed to the transcoding device in real time for transcoding processing, and pushing is not required to be performed after the complete live broadcast stream information is copied (for example, a live broadcast terminal does not send live broadcast stream information generated by anchor live broadcast any more), and with regard to the acquisition process of the video fragment file, reference can be made to the description of the corresponding part in the above embodiment, which is not described in detail in this embodiment.
Step S42, in the live broadcast process, transcoding the obtained video fragment files to obtain corresponding live broadcast playback fragment files;
and S43, obtaining the live playback file of the live content by utilizing a plurality of live playback slicing files aiming at the same live content.
After receiving each video fragment file pushed by computer equipment such as a live broadcast terminal or a live broadcast server and the like executing a live broadcast content recording function, the transcoding equipment can directly transcode the video fragment file without waiting to obtain an MP4 video file, record the video fragment file as a corresponding live broadcast playback fragment file, and then send the video fragment file to the storage equipment for storage.
Optionally, the transcoding device may also send all live playback segment files for the same live content to the storage device for storage after obtaining the live playback segment files, or send the live playback segment files to the storage device for storage after performing splicing processing, and the like, which is not limited in the present application.
It should be understood that, because the transcoding device may obtain video segment files of live content for different live rooms at the same time, in order to distinguish the live playback segment files obtained by transcoding, a live identifier corresponding to the live content/the live room may be configured, so that the live identifier and the live playback segment files are carried and sent to the storage device for storage, so that when the storage device pushes the live playback file, the live playback file corresponding to the live content required to be played back by the terminal may be selected according to the live identifier, and details are not given in the implementation process of the present application.
As can be seen from the above analysis, the live playback file of any live content obtained by the transcoding device may include a plurality of live playback segment files of the live content, and may also include a video file or the like spliced from the plurality of live playback segment files, which is not limited in this application.
In conclusion, the live content recording side adopts a fragment recording mode, in the live broadcasting process, each recorded video fragment file is pushed to the transcoding equipment in real time, the transcoding equipment can transcode the received video fragment file in real time to obtain the corresponding live playback fragment file, and therefore after the live broadcasting is finished, the transcoding equipment only needs to spend a short time to transcode the last video fragment file to obtain the live playback file with complete live content, the time for waiting for transcoding by a user after the live broadcasting is finished is greatly shortened, and the user experience is improved.

And S53, pushing the live broadcast playback segment files to a storage device, and sequencing and storing a plurality of live broadcast playback segment files of the same live broadcast content by the storage device according to the recording time sequence.
In the embodiment of the application, after receiving any video fragment file, the transcoding device can transcode the received video fragment file into a live playback fragment file with a preset video format (such as an MP4 video stream format), and after transcoding is successful, the live playback fragment file can be sent to the storage device to be stored, so that loss is avoided. As described in the corresponding parts above, the storage device may store each received live playback segment file in a table manner after associating it with the live identifier of the live content, so that a plurality of live playback segment files of the same live identifier may be sorted and stored according to the recording time sequence/transcoding time sequence.
In some embodiments, the transcoding device may also perform splicing processing on a plurality of live playback segment files for the same live content according to the recording time sequence after transcoding all video segment files of the same live content successfully, so as to obtain a live playback file of the live content, and then send the live playback file to the storage device for storage.
In still other embodiments, the transcoding device may splice the obtained live playback segment file with a previously successfully transcoded live playback segment file of the same live content each time the transcoding is successfully performed by one video segment file, that is, after the transcoding is successfully performed by the first video segment file of a certain live content, it is determined that the live playback segment file obtained by the current transcoding is not the first live playback segment file of the live content, the live playback segment file may be spliced to the end of the last live playback segment file of the live content until the last live playback segment file of the live content is successfully spliced, and compared with a case where all video segment files of the same live content are spliced after waiting for the successful transcoding, the splicing latency time is reduced by the implementation manner in which the two processes of the transcoding process and the splicing process are simultaneously performed.
Optionally, after transcoding is successful each time, the transcoding device may also push the live playback segment file obtained by transcoding each time to the storage device, store a plurality of live playback segment files for the same live content by the storage device, or splice a plurality of live playback segment files for the same live content, and store the live playback file for the live content.
In still other embodiments, as described above, the transcoding device may also not splice multiple live playback segment files of the same live content, sequence the multiple live playback segment files of the same live content obtained through transcoding directly according to the recording time sequence, obtain a live playback file of the live content, and send the live playback file including the multiple live playback segment files to the storage device for storage.
Certainly, the transcoding device may also send the video file of the spliced live content and all live playback segment files of the live content that are not spliced to the storage device for storage, so as to meet different subsequent viewing/processing requirements.
In the live playback processing method described in the foregoing embodiments, after a storage device obtains a live playback file of any live content, when a user needs to watch a live playback video, a live playback file pull request/live playback instruction including a corresponding live identifier may be sent, and the storage device obtains the live playback instruction, or in a case where a live playback instruction for the live content having the live identifier is generated based on the live playback file pull request, a live playback file associated with the live identifier may be selected and pushed to a terminal that sends the live playback instruction, and the live playback file is output by the terminal, and the live playback video is played.
Under the condition that the live playback files stored in the storage device are a plurality of live playback fragment files aiming at corresponding live content, the storage device can determine at least one live playback fragment file corresponding to the playback time contained in the live playback instruction, and then push the determined at least one live playback fragment file to a terminal sending the live playback instruction, so that the terminal can carry out live content playback according to the live playback fragment files and the playback time, therefore, under the condition that a user only needs to watch live playback video in a certain time period, the storage device does not need to distribute the complete live playback file of the live content to the terminal, the waste of transmission resources is reduced, and the live playback efficiency and accuracy are improved.
