I havent tried it direct with the cli and mp4box direct, but where is the option in yamb which would do the equivalent of -sbr?
Its just i've stumbed across a problem whereby, when yamb imports and mux's an he-aac file, the resulting track in the mp4 container becomes altered.
I analysed the file by converting to wav and examining in nero wave editor.
The bpm is different and hence the track length is out.
In detail, the track starts to early and by the end, it overruns.
This does not happen if the aac is LC or if i mux with directshow based filters (have tried elecard and 3ivx).
If i understand the mp4box documentation right, the -sbr is only for playback tagging, so even if YAMB does do the switch bit correctly, this could be a bug.
Has anyone else seen this?
Thanks
Neil
