Could anyone please shed any light on why the defaultSampleDurations in moof are different between LC & HE-AAC at the same sampling rates? >> Thanks, >> >> Ronak >> _______________________________________________ >> ffmpeg-user mailing list >> [email protected] <mailto:[email protected]> >> http://ffmpeg.org/mailman/listinfo/ffmpeg-user >> <http://ffmpeg.org/mailman/listinfo/ffmpeg-user> >> >> To unsubscribe, visit link above, or email >> [email protected] <mailto:[email protected]> with >> subject "unsubscribe". > > _______________________________________________ > ffmpeg-user mailing list > [email protected] <mailto:[email protected]> > http://ffmpeg.org/mailman/listinfo/ffmpeg-user > <http://ffmpeg.org/mailman/listinfo/ffmpeg-user> > > To unsubscribe, visit link above, or email > [email protected] <mailto:[email protected]> with > subject "unsubscribe". _______________________________________________ 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".
