  • How can select only two audio streams in a video and feed it to the ebur128 filter wiithin ffmpeg ?

    18 avril 2017, par Edwin

    I want to use FFmpeg to analyze the loudness of an MXF video file.
    I have an MXF file with 8 mono audio streams. I only want to feed the first two streams through the ebur128 filter. But I can’t find a way to do that. The FFmpeg documentation is not clear to me, as I am fairly new to FFmpeg.

    I tried several things :

    ffmpeg -i source.mxf -nostats -filter_complex ebur128=dualmono=true:panlaw=-3.01dB -f null -

    I am sure it’s just that I don’t have the filtering syntax right. But hey... I’m a newbie...

    ffmpeg -i myVideo.mxf -nostats -filter_complex [0:a:0][0:a:1]amerge; ebur128=dualmono=true:panlaw=-3.01 -f null -

    And this is the resulting console output :

    I would like to transform them into one 5.1 audio channel

    I try this line of code :

    D:\test-remapping>ffmpeg -i "MelleParadis_PART1_CONSTANTE.mov" -c copy -c:a ac3 -map 0 mlle5.1.mov

    the console replies "NOT ENOUGH SPACE" and stop...
    of course there's still some space in my hard drive...
    How could I map all the 6 mono streams into 5.1 ?
    thanks in advance.
