[Mp4-tech][Audio][Software]: Reference software for MPEG4-AAC

[Umang Garg]

Dear Members,
The audio reference software available from 
ftp://mpeg4vm@ftp.tnt.uni-hannover.de/incoming/cvs/ contains two 
instances of the Audio decoder.  The first instance is the 
mp4AudVm_Rewrite and the second instance is the mp4mcDec. 
I understand that mp4mcDec is the multi-channel Decoder for MPEG4-AAC 
while mp4AudVm_Rewrite supports MPEG4-AAC along with other MPEG4 Audio 
decoders.
(Q1) Does mp4AudVm_Rewrite support multi-channel decode ?
(Q2) For MPEG4-AAC, are both the instances of the decoders( 
mp4AudVm_Rewrite and mp4mcDec) equivalent ?
(Q3) For MPEG4-AAC, are both the instances of the decoders( 
mp4AudVm_Rewrite and mp4mcDec) updated regularly(in the weekly snapshots) ?
(Q4) Do both references, mp4AudVm_Rewrite and mp4mcDec, support SBR 
decoding ?
(Q5) For MPEG4-AAC, is there any difference between mp4AudVm_Rewrite and 
mp4mcDec, that should encourage the usage of one as against the other ?
Your help is requested.
Regards,
Umang Garg
