Now try to play the files in the player, such as VLC.
And that's what we get: the first fragment (00000.mp4) played well, no

How to get rid of the delay with black screen at the beginning of the segments? Maybe ffmpeg to pass parameters, or third-party software is able to correct the obtained segments mp4?
