What you need is to identify the "embedded processor" and get the codec (and
parser) required for this platform. You can either buy it off the shelf or
if your company has a DSP/Video group, try implementing it.

All MPEG-4 decoders would be able to play all MPEG-4 streams. There is no
question of compatibility here.

That is because Microsoft's Windows Media Player does not have support for
MPEG-4 files. This is not a compatibility issue. WMP does not support a lot
of good formats because Mr. Gates seems to want to push WMA & WMV, but that
is another issue! Use Quicktime, Nokia Multimedia Player, or Phillips
Platform player for MP4 files.
