Abstract

The present invention discloses a video recording method and system, wherein the method includes: reading the audio data stream of the target video in real time, and converting the video frame of the target video into video frame data; monitoring the audio data stream of the target video Playing state, when the playing state of the target video represents the suspension of the live broadcast, record the starting time node when the live broadcast is suspended, and when the playing state of the target video represents the live broadcast recovery, record the termination time node when the live broadcast resumes; based on The start time node and the end time node calculate the amount of data to be inserted, and before the audio data stream when the live broadcast resumes, insert audio empty packet data equal to the calculated amount of data; The audio data stream inserted with the audio empty packet data and the video frame data are synthesized into a recorded video file. The technical solution provided by this application can ensure that the recorded video files maintain the synchronization of audio and video.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a video recording method and system. Background technique [0002] With the continuous development of live video technology, more and more users tend to watch live video on the live video platform. Live video has a high timeliness, and while watching live video, users can also communicate with the host or other users in real time by posting barrage. [0003] At present, in order to allow users who miss the live broadcast time to watch the live video again, the current playback device can provide a video recording function. Specifically, for the screen content of the live video, the screen content may be captured as a video frame by means of a screenshot. The advantage of this processing is that it can retain some additional visual effects in the picture content. For example, special effects such as answering questions and swiping gifts during the live broadcast can be ret...
