Yes I would totally agree with you, except I can't find a single "-ss" time that seems to "accidentally hit an i-frame" and work the way you and I would expect it to...though I haven't looked into it much... -r _______________________________________________ Libav-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/libav-user
