True. i started looking at it in the past, but then i solved my problem  
in other ways and never finished it. If you want to add it fell free to  
do it, add it to demux_audio.c takeing the wav code as an example.

do you mean VLC or mplayer? mplayer have speed problems on twos, i  
added a patch to fix them in the past, but it broke other stream.  
Probably the problem have to be fixed at demuxer level, not at codec  
level.

have a look at sh_audio->ds->ss_div and ss_mul, they are the key to it.
i'm trying to fix the same problem for alaw/ulaw/mace too.
there are different version of qt headers, the newest have the data to  
fill div and mul automatically, for the older ones you have to fill it  
depending on codec parameters.

I'll try to be more detailed when i'll submit the patch for alaw/ulaw.
