This looks more like uncompressed YUV or another raw format. 
If you know the dimensions, you maybe can check using mplayer -rawvideo
option.

Anyway, it's surely no raw MPEG4 stream. That would have to start with 

000000 b0010000 01000003

because all startcodes are 0x000001** 

Also, the suffix .mp4 usually means MPEG4/Quicktime container format, not
a raw stream. Still, that would look different, too.
