I am currently recording video with blackmagic's prorecorder. I transcode video on-the-fly to mp4 video container with ffmpeg. Duration is unknown as I'm transcoding .ts that prorecorder is outputting to named pipe.

My goal is to try to play this file with browser, while stream is still being recorded - Playback is great, but problem is that when I open file, duration is defined to current recording time.

So, question is - I would like to generate a "fake" moov atom for duration of fe. 8 hours with ffmpeg, and then start recording mp4 file as I'm already doing. How could I do this?

Documentation that I checked and I think it's relevant - https://ffmpeg.org/ffmpeg-formats.html#MOV_002fMP4_002fISMV I also saw this on stack: Is it possible to fake a (mp4) moov atom?

我有一个类似的问题，只是在编码了近 2000 个视频后才发现它。我没有重新开始，而是使用此命令插入 moov atom：

/usr/bin/ffmpeg -i ./input.mp4 -c:v copy -movflags faststart -strict -2 ./output.mp4
