This is carried over my post in A/V formats forum, cause it now appers to be an aacenc problem...:
I today made an XVID-AVI (625 MB) and an AAC-Audiofile (72,5 MB) from a whole movie.
Both play fine, when muxed to MP4 alone in wmp4player, audio even in RealOnePlayer/Envivio.
The movie is 1:39:06 long.
Audio-file only, RealOne shows exactly that duration and plays fine (WMP4Player has no time stamp output).
Audio+Video muxed: WMP4Player plays movie, but audio is heavily off-sync. If opened in RealOne/Envivio it doesn't show the video, but it plays audio and shows a time of 1:43:18...something fishy here.
With MP4Creator I tried lots of combinations of rate, optimize, hint and interleave and order of muxing and whatever always with the same result. Anyone can help?
I narrowed it down a bit...it is the audio that is actually 1:43:18 long after encoding with Psytel AACENC....playing with WinAmp Plugin (showing time remaining) shows correct length from the beginning and then when reaching 0.00 starts to count up again....so there must be some info in the file it is 1:39:06 but actually it isn't...I tried with -streaming and with -streaming profile 2 both times same result...input wav was 16 bit int and was correct.
AACEnc seems to somehow timestretch the file...
Anyone knows of any related bug in AACENC V2.15?
