Methods for media file recording, and recovery after power failure, and related devices

摘要

A method for providing media files. A video bitstream file, a video meta file, and an audio bitstream file are first runtime generated during recording. After the recording is suspended, an audio header file is generated corresponding to the audio bitstream file, and a video header file is generated corresponding to the video meta file. The audio header file and the video header file are merged into an AV header file, and the video bitstream file and the audio bitstream file are merged into an AV bitstream file. The AV bitstream file and the AV header file are further merged into a media file.
