The video format cached at station b on the windows side is in m4s format. How to convert it to mp4 format is recorded here.

For details, please refer to " Super detailed, how to convert the cached m4s file of station B into mp4 format "

Let me talk about the specific idea: as shown in the figure below, station b mainly caches two m4s files, the large one is video, and the small one is audio.

We need to convert the m4s of the video to MP4, and the ms4 of the audio to MP3, and then use FFmpeg to synthesize the two.

But the video and audio cached in the picture below still have 00000000 at the beginning, which needs to be deleted with notepad++ before they can be synthesized with FFmpeg.

When synthesizing, the command line can be synthesized directly with the script language.
