  • FFmpeg works out mp3 duration with file input, but fails with pipe ?

    16 août 2012, par user1599160

    I am trying to get PCM data from mp3's using ffmpeg, but the files are stored on a database, gridfs, so I am trying to use pipes to give ffmpeg the data with some sucess, however there is one file which ffmpeg handles correctlt if fed the filename as an input, and incorrectly when given the file as a pipe :( any idea why ?

    ffmpeg -i - -f s16le -acodec pcm_s16le output.raw &lt; testMp3s/test-corrupt.mp3

  • Ffmpeg pipe stream glitch

    30 avril 2015, par user3664517

    I want to process ffmpeg raw video stream, and I can’t understand why this code produces glitches. What’s wrong ?

    ffmpeg -i in.mp4 -f image2pipe -pix_fmt rgb24 -vcodec rawvideo - | 
    
ffmpeg -f rawvideo -vcodec rawvideo -s 1980x1080 -pix_fmt rgb24 -r 24 -i - -an out.avi

    Thanks !
