  • What is wrong with the following ffmpeg command

    14 août 2013, par Brad

    What is wrong with the following ffmpeg command. Originally this had -sameq instead of the -qscale:a 0

    Command :

    ffmpeg -loglevel debug -threads 4 -i sample-in.mpg -ss 00:00:01 -t 00:00:05 -f image2 -y sample-frames/frame%d.png -acodec copy -qscale:a 0  -y sample.mp3

    I did a few edits removing the -sameq and replacing it with -qscale:a 0 which probably is wrong.

  • how to use crop filter twice in ffmpeg

    1er mars 2015, par user1502679

    I want to use crop filter in two different locations, for example top left + bottom right and to merge them, how can I do this ?

    I want to use the code once, not to make with two independent crops and merge after that.

    EDIT : an image : http://alexvorn.com/wp-content/uploads/2013/07/ffmpeg-multiple-crop.png

  • Why ffmpeg command results in blank video ?

    17 juillet 2013, par kheya

    I 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
