With the popularization of the internet, live broadcasting also starts to be more and more popular. Because the live broadcast has timeliness, some live broadcast viewers may not watch in time in the live broadcast time or want to watch repeatedly after watching a certain live broadcast, and based on the requirements, live broadcast playback videos can be generated according to live broadcast contents for users to watch.
In the prior art, playback videos are sequentially generated according to the end time of each live broadcast, and the playback videos of the live broadcast are released after the playback videos of all the definition gears of each live broadcast are generated. Many steps are needed from the end of live broadcast to the generation of video playback, including transcription, transcoding and the like, one hour of live broadcast may require one hour to generate playback video, the speed is low, and the user experience is influenced
In order to solve the problem, the present disclosure provides a live playback generation method and a device applying the live playback generation method, and the live playback generation method is first explained in its entirety. The live playback generation method can be applied to a content platform server, and comprises the following steps S101 to S103, referring to FIG. 1:
in step S101, after detecting that live broadcasting is finished, creating a generation task of a playback video of the live broadcasting;
live playback video is generated based on the live streaming content of the live broadcast. Typically, after a live broadcast is finished, the live playback video is ready to be generated.
Specifically, the screen recording file of the live broadcast can be acquired from the cloud storage, and the acquired screen recording file is converted to generate the playback video of the live broadcast.
Referring to fig. 2, the live broadcast source station is a total live broadcast push stream source station from which all live broadcasts of all anchor can obtain the original live broadcast push stream. In the actual live broadcast process, a recording service is called to record/record a screen of the live broadcast, and a fragment screen recording file is obtained, so that in order to ensure the recording speed in the real-time screen recording and reduce the resources consumed by recording, the whole live broadcast cannot be recorded into a whole file, but can be recorded into a plurality of fragment files, namely fragment screen recording files, and the fragment files can be distributed on a webpage as video playback files and can be watched by a user through a webpage player after certain conversion processing.
In an embodiment of the present disclosure, the fragmented screenplay file may be an FLV format file.
In another embodiment of the present disclosure, live content may be censored in real time based on the real-time recorded segment screen file, so as to ensure that the live content does not include illegal content. Specifically, after each screen recording file is recorded, live content in the screen recording file is detected.
Specifically, the recognition model may be trained in advance, and image recognition may be performed on each frame in the screen recording file to determine whether the image contains the illegal content. If illegal contents are detected in a certain video recording screen file, a follow-up processing strategy is determined based on the illegal types of the illegal contents, and the follow-up processing strategy can comprise pushing a reminding message to a main broadcast, automatically cutting off the live broadcast and/or closing the main broadcast, and the like.
In an embodiment of the present disclosure, after detecting that the live broadcast is over, a determining step may be further performed to determine whether the live broadcast should generate a playback video.
Specifically, it may be determined whether the live broadcast account has a video playback generation permission, and in an actual application, some live broadcast accounts may not have a video playback generation permission. For example, a game live broadcast account has a generation authority for playing back a video, and a dance live broadcast account does not have a generation authority for playing back a video.
And under the condition that the live broadcast account has the generation permission of the playback video, whether the live broadcast anchor closes the playback video generation success of the live broadcast can be continuously judged. In practical applications, the anchor may want some of its live broadcasts to be only available for viewing once and not to be recorded, in which case the anchor may choose to turn off the playback video generation function for that live broadcast. And under the condition that the generation function of the live playback video is judged not to be closed by the anchor, creating a generation task of the live playback video.
In step S102, determining a corresponding task execution channel according to the type of the live broadcast account of the live broadcast, and submitting the generated task to the determined task execution channel to generate at least one definition playback video corresponding to the live broadcast, wherein different task execution channels have different execution rates for generating tasks;
in this embodiment, a plurality of task execution channels are provided, and each task execution channel corresponds to an account type of a live account. And after the live broadcast is detected to be finished, submitting the live broadcast generation task to the corresponding task execution channel according to the live broadcast account type.
The purpose of setting up multiple task execution channels is to prioritize the generation of playback videos of different account types. In one embodiment, the plurality of task execution channels may be set as task execution channels of different levels, the account types may be set as account types of different levels, and after the level corresponding to the account type of the live account is determined, the generation task of the live account is submitted to the task execution channels of the same level.
For example: after the live broadcast of the anchor A with the account type of the primary account is finished, a generation task of a playback video is submitted to a primary task execution channel; at the same time, the B anchor live broadcast with the account type of the secondary account is finished, and the generation task of the playback video is submitted to a secondary task execution channel. Because the task processing rate in the secondary task execution channel is lower than that of the primary task execution channel, the generation speed of the playback video of the anchor A is faster than that of the anchor B.
In practical application, important official live broadcast accounts at all levels, news live broadcast accounts and the like can be set to be account types at higher levels, and the accounts can be submitted to a high-level task execution channel to process generation tasks of playback videos more quickly. And setting the entertainment live account, the merchant live account and the like as relatively low-level account types.
In an embodiment of the present disclosure, the account types of the live broadcast account may be divided into two types, that is, a first type account and a second type account, which respectively correspond to a special type account and a common type account, where:
a) if the live broadcast account is a first type account, submitting the live broadcast playback generation task to a high-priority task execution channel, wherein the first type account is a pre-designated special type account;
b) and if the live broadcast account is a second type account, submitting the live broadcast playback generation task to a low-priority task execution channel, wherein the second type account is a pre-designated common type account.
It can be known that the number of task execution channels may be set according to a specific application scenario, and there may be two or more, which is not limited in this embodiment.
Referring to fig. 3, each task execution channel may call a video processing service, and sequentially execute each generated task according to the submission order of each generated task. Different task execution channels are allocated different amounts of processing/computing resources so that the generated tasks in different task execution channels have different execution rates.
For example, three servers are used for processing the generation task of live video playback, two of the servers are allocated to process the task in the high-priority task execution channel, and one of the servers is allocated to process the task in the low-priority task execution channel. In this way, when the total processing resources for processing the generation tasks are limited, the generation tasks of the high-level accounts are not blocked even if the generation tasks of the low-level accounts are preferentially submitted due to the existence of different channels.
In step S103, in the execution process of the generation task, if the generation of the playback video with any definition is completed, the playback video with the definition is published until all the playback videos with the definition are published.
In the process of executing the generating task, if the generation of the playback video with any definition is finished, the playback video with the definition is published on the playback video display page of the server side until all the playback videos with the definition are published on the playback video display page of the server side.
When generating playback video, it is generally necessary to generate playback video with multiple resolutions, such as 540p (normal), 720p (high definition), and 1080p (ultra definition). That is, when the generation task is executed, it is necessary to perform generation operations for playback videos of a plurality of resolutions.
In the conventional scheme, after all the playback videos with the definition are generated, the service side is notified to issue the playback videos. In this embodiment, for a live broadcast, as long as one of the playback videos with one definition is generated, the service side is notified to issue the playback video with the definition. It should be noted that, at this time, the generation task of the live playback video is not executed to the end, and the generation task is executed only after all the live playback videos with all definitions are completely generated.
For example: in the generation task, live playback videos with three definitions, namely 540p (normal), 720p (high definition) and 1080p (ultra definition), need to be generated, wherein the 720p (high definition) playback video is generated first, and then the 720p (high definition) playback video is processed and issued first until the other two definitions playback videos are also generated and issued to a playback video display page.
Therefore, the method provided by the invention can distinguish the live broadcast which cannot be of the type, more reasonably distributes the video processing resources, realizes the selective and rapid release of the live broadcast playback, and improves the user experience.
Fig. 4 is a flowchart illustrating a more specific live playback generation method according to an exemplary embodiment, where the live playback generation method may be used in a platform capable of performing live playback generation, and as shown in fig. 4, the method may include the following steps S401 to S404:
in step S401, after detecting that live broadcasting is finished, creating a generation task of a live playback video when a live broadcast account of the live broadcasting has a generation permission of the playback video;
in step S402, a corresponding task execution channel is determined according to the type of the live broadcast account, and if the live broadcast account is a special type account, the live broadcast playback generated task is submitted to a high-priority task execution channel; if the live broadcast account is a common type account, submitting the playback generation task of the live broadcast to a low-priority task execution channel;
in step S403, a fragment screen recording file generated in the live broadcast process is obtained, and a video processing service is invoked to perform file merging and format transcoding on the fragment screen recording file, so as to generate a playback video file suitable for webpage playing;
in step S404, in the execution process of the generation task, if the generation of the playback video with any definition is completed, the playback video with the definition is published on the playback video display page of the server, until all the playback videos with the definition are published on the playback video display page of the server.
Specifically, the generation of the playback video includes merging and transcoding a fragmented video recording file (such as an FLV file) obtained by video recording in a live broadcast process. And after receiving the merging and transcoding request, the video processing service merges and transcodes the partitioned screen-recording file. When any gear of 540p, 720p and 1080p is transcoded successfully, a transcoding success message is sent to a service party.
After monitoring a message that transcoding of any definition video is successful, the back end of the service side calls a video generation service for the playback video to generate a photosid, associates other data (such as praise, barrage and the like) recorded in the live broadcast process with the photosid, and releases the photosid on a playback video display page. The user can see the playback video on the playback video presentation page (in which case only the live playback video of the corresponding definition can be seen). And after all the playback videos with the definition are generated and are concurrent, the user side can see all the playback videos with various definitions.
With the popularization of the internet, live broadcasting also starts to be more and more popular. Because the live broadcast has timeliness, some live broadcast viewers may not watch in time in the live broadcast time or want to watch repeatedly after watching a certain live broadcast, and based on the requirements, live broadcast playback videos can be generated according to live broadcast contents for users to watch.
In the prior art, playback videos are sequentially generated according to the end time of each live broadcast, and the playback videos of the live broadcast are released after the playback videos of all the definition gears of each live broadcast are generated. Many steps are needed from the end of live broadcast to the generation of video playback, including transcription, transcoding and the like, one hour of live broadcast may require one hour to generate playback video, the speed is low, and the user experience is influenced
