Background
With the full rise of the live broadcast industry, the broadcast mode of the live broadcast is more and more popular. Meanwhile, with the rapid increase of the live broadcast room, the live broadcast content is more and more abundant, and as the live broadcast content has the characteristics of timeliness and abruptness, the recording of wonderful content in the live broadcast process becomes a problem to be solved.
Currently, the retention of wonderful content in the live broadcast process mainly adopts the following two modes:
the first scheme is as follows: obtained by post-cropping the highlight video. As shown in fig. 1, immediately after the live broadcast starts, recording is started, and the whole live broadcast process is completely recorded and stored in a storage medium. And after the live broadcast is finished, extracting the recorded video from the storage medium to review and clip, and finally storing the wonderful video segment obtained by clipping in the storage system again for sharing and reviewing.
Scheme II: and when finding the wonderful video, the anchor client pushes a recording request to a background to record the wonderful video. As shown in fig. 2, in the live broadcast process, the anchor continuously pushes live broadcast content to the live broadcast server, when there is a recording demand, a recording request is sent to the recording server through the anchor client, and the recording server responds to the recording request and pulls audio and video data from the live broadcast server for recording.
However, the first scheme stores not only the highlight video obtained by final editing, but also the content in the whole live broadcast process, and the storage cost is huge, and most of the stored whole live broadcast content is useless data. Secondly, a wonderful video needs to be edited from the recorded video manually, so that the timeliness is low, and the labor cost cannot be ignored. In the second scheme, the audio and video transmission rate usually lags behind the instruction transmission, and the highlight video is usually very short, so that the final recorded content is not the content desired by the anchor due to the asynchronous transmission rate, and the highlight video is not wonderful any more.

In one possible embodiment, the extracting of the audio-video data in the interval from the start of the recording instruction to the end of the recording instruction may include: recording is started from the first I frame of the audio and video data after the recording instruction is started until the I frame before the first recording ending instruction after the recording instruction is started is recorded, and recording data are obtained. Data streams output by live broadcast protocol data are shown in fig. 12, where av tag is audio/video data, command tag is instruction data, and each tag data has information such as a timestamp, so as to ensure that related data packets are sent in order. And the audio and video data between the start recording instruction and the end recording instruction is wonderful video data to be recorded. In order to simplify the logic of the recording server, the first video tag data after the instruction tag is inserted into the live protocol data is encoded into I frame data, so that the recording server can record from the I frame, and the problem of screen omission of the first GOP is avoided.
In a possible embodiment, live broadcast content recording is performed according to a recording instruction while the live broadcast protocol data is output, and at the same time, the output live broadcast protocol data is discarded, and only the recorded audio and video data is stored, so that the purpose of saving storage space is achieved.
