[FFmpeg-user] way to reencode corrupted video

[BloodMan]

Hi,


Really many... for example:

ffmpeg -i test out.mp4

ffmpeg -i test.mp4 -c copy temp.mp4; ffmpeg -i temp.mp4 out.mp4

ffmpeg -i test.mp4 -c copy -bsf:v h264_mp4toannexb temp.mp4;
ffmpeg -i temp.mp4 out.mp4

[many eternities later]

ffmpeg -loglevel info -stats -err_detect ignore_err -hide_banner 
-nostdin -threads 16 -y -strict experimental -fflags 
+genpts+igndts+ignidx+discardcorrupt -i test.mp4 -movflags faststart 
-video_size 1920x1080 -r 25 -pix_fmt yuv420p -c:v libx264 -preset faster 
-profile:v high -level 51 -crf 22 -tune film -c:a aac -b:a 160k -ac 2 
-ar 48000 -y -f mp4 -bsf:v h264_mp4toannexb out.mp4

and nothing ;)

Output is always same, no relation with commandline, indicates bitstream
