Change ffplay spectrogram colours


How can I make the live spectrogram that ffplay renders while playing audio use colours?


Solution

  • The showspectrum filter is what you're looking for.

    To force ffplay to use colours:

    ffplay -f lavfi "amovie=audio.m4a,asplit[a][out0];[a]showspectrum=color=intensity:slide=1[out1]"
    

    outN - non-documented output link names.

    To generate video:

    ffmpeg -i audio.m4a -lavfi showspectrum=color=magma:slide=1 spectrum.mp4
