MP4 is just the container format. It can contain video encoded with
various codecs, including h264, divx, xvid, and others. Additionally,
you can have various encoding profiles and resolutions, only some of
which may be supported by your VDPAU hardware. Without knowing the
specifics it's hard to say whether or not VDPAU should support it, but
there are most definitely encodings it will not handle. As was
recently pointed out in another thread, it doesn't handle interlaced
VC1 videos (apparently common on some British blurays). I've also, on
a few occasions, accidentally transcoded a video to a resolution
greater than 1920x1080. The resulting video exhibited very poor
performance (lots of pausing/stuttering).
