Is it? I thought it was using the library API for display and just
inigo for rendering. This is just a technicality; inigo is just a tiny
command line interface to the API.

Only if you want to give up video filters or transitions. It might be
rather tricky to switch between the CPU and VDPAU for the filtered and
non-filtered portions especially for AVCHD where we already have some
seeking issues.  My brief review of the VDPAU API lead me to believe
it is easy to get the decoded image and not use the display API. I
just need to look into the details.
