Investigate possibility to detect and heal corrupted mp4 video files with ffmpeg

[azarouski]

subj

[azarouski]

to check file integrity:

ffprobe -v trace video.mp4

---

to make recording more fail safe add movflags : (https://superuser.com/a/1530949)

ffmpeg ... -movflags +frag_keyframe+separate_moof+omit_tfhd_offset+empty_moov ... video.mp4

this option increases the output file size by ~2-3%

to test this issue you need to try to break process of video recording
