As far as I can tell, there is no way (currently) for ffmpeg to re-use the file from the first pass. You have to take the file's parameters yourself in order to construct a filter command for the second pass: http://k.ylo.ph/2016/04/04/loudnorm.html Also see the quoted scripting example (this is in ruby, but could easily be done in many scripting languages): https://gist.github.com/kylophone/84ba07f6205895e65c9634a956bf6d54 Cheers, Moritz _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
