Assuming that m4b is the same format as m4a, it should be played without forced transcoding, even if there is a need for transcoding then -a copy should be used instead of force reincoding to higher bitrate. Please also note flags passed to ffmpeg "-strict experimental -ab 384000" are not accurate, as ffmpeg does not require -strict experimental any longer (aac is quite stable) and bitrate is hardcoded as orginal bitrate was lower, thus probably should be just omited. P.S. Attached the file m4b-transcoding.txt Edited January 7, 2019 by yermak Link to comment Share on other sites More sharing options...
