[Mp4-tech] Re: Mp4-tech Digest, Vol 34, Issue 7

[pankaj bajpai]

Hi Maria,
Mpeg4 (part-2) decoder cannot decode H.264 stream.
Similarly, I think (let me correct if I am wrong) H264 decoder cannot decode Mpeg4 
Simple profile stream.
Actually the bitstream structure is entirely different. Like H264 has 4x4 and other 
sub partition of 16x16, while Mpeg4 has only 8x8 or 16x16.
With regards
