Hi Experts,

I have a couple of question to ask, it regarding Codec support on DM6446 /
DVEVM. I have the decodeCombo.x64p package. And i am using the same to run
MPEG2 / MPEG4 video files. But im facing a strange problem. I can play MPEG
4 files . But some MPEG 4 files don't play at all . Why? I would like to
know what type of MPEG4 does TI decodeCombo support ?

Can somebody guide me to TI's MPEG4 codec details ? And doesn't it plays
video with " B" frames ?

Warm Regards,
Sagar
