Why ffmpeg command results in blank video ?
17 juillet 2013, par kheyaI am trying to conver mov file to H264 encoded mp4
Same command converts another mov file just fine.But fails for a particular mov file. Original video is 29.6MB after conversion I get 966KB
I get the sound and duration right. But all the frames are black even though original video is fine.
Here is the command :
ffmpeg -i file3.mov -movflags +faststart -vcodec libx264 -preset slow -crf 20 -vf -threads 0 -acodec libvo_aacenc -b:a 128k "file3.mp4"Here is the result of ffmpeg -i : >ffmpeg.exe -i file3.mov
