  • With ffmpeg's image to movie feature, is it possible to pass in frames over a period of time versus all at once ?

    2 novembre 2013, par Zack Yoshyaro

    For the purpose of making a time lapse recording of desktop activity, it is possible so "stream" the frame list to ffmpeg over time, rather than all at once in the beginning.

    Currently, it is a two step process.

    1. save individual snapshots to disc

      im = ImageGrab.grab()
      im.save("frame_%s.jpg" % count, 'jpg')

    2. compile those snapshots with ffmpeg via

      ffmpeg -r 1 -pattern_type glob -i '*.jpg' -c:v libx264 out.mp4

    It would be nice if there were a way to merge the two steps so that I'm not flooding my hard drive with thousands of individual snapshots. Is it possible to do this ?

  • How To Specify FFMPEG Input Volume For Multple Input Files

    30 septembre 2014, par gbd

    I have 6 similar/separate audio input files feeding into ffmpeg - no video. I’m mixing the 6 input channels down to a stereo output using amix and that works fine. But now I need to change the volume of each individual input channel before the mix down - or maybe as part of the mix down. I’ve looked at and tried aeval (which seems very slow) in the form

     'aeval=val(0)*volChg1:c=same|val(1)*volChg2:c=same|val(2)*volChg3:c=same|val(3)*volChg4:c=same|val(4)*volChg5:c=same|val(5)*volChg6:c=same'

    but that only seems to change the volume of the first channel.

    So the whole input part of my ffmpeg expression looks something like this right now :

    -i inFilePath1 -i inFilePath2 -i inFilePath3 -i inFilePath4 -i inFilePath5 -i inFilePath6 
    
-filter_complex 'aeval=val(0)*$volChg1:c=same|val(1)*$volChg2:c=same|val(2)*$volChg3:c=same|val(3)*$volChg4:c=same|val(4)*$volChg5:c=same|val(5)*$volChg6:c=same','amix=inputs=6:duration=longest'

    $volChg1-6 are php variables containing the individual volume multipliers - 0.5 for example should halve the volume of that individual channel while 1.0 would leave it unaffected. How do I do this ?
