You can enable AAC-Main (and thus prediction) in two ways: set the profile via -profile:a aac_main or set the prediction flag via -aac_pred 1. Setting one will set the other as well, since you can't have prediction without the profile being set and you can't have the profile set without prediction (well you can but it would be a hack as you'd just set all scalefactor bands to disable prediction). -- Ticket URL: <https://trac.ffmpeg.org/ticket/2686#comment:479> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker _______________________________________________ FFmpeg-trac mailing list FFmpeg-trac@avcodec.org http://ffmpeg.org/mailman/listinfo/ffmpeg-trac
