  • avformat/avc : Add functions to split access unit into list of NALUs

    avformat/avc : Add functions to split access unit into list of NALUs

    18 août 2022, par Luka

    I have deleted a video file from an SD card and then 'undeleted' it with tool called testdisk for Linux. It saved complete file (6Gb), but video seems broken (can't be played by any video players) and ffprobe reports :

    I'm no programmer, but have used ffmpeg a lot. How can I remux (or even re-encode) such file to fix this and make the file usable for further work ?

    &#xA;

    I have created a 10seconds snippet with ffmpeg -i MVI_1399.MP4 -t 00:00:10 -c copy MVI_1399_10sec.mp4 for anyone to check. I also created a ten second snippet from a functioning clip from the same camera (I presume same codec parameters etc) :
