Just ran into an issue with the old system that this would have
handled just fine.
In old system one needs to know height/width of video from demuxer
to check for hw support of a specific width/height (for some silly reason
some nvidia chipsets have issues with some video widths).
If demuxer doesn't provide this info, one would have to start decoding
without hw support to find this out.
With the system, the init of vdpau is delayed untill we have started
decoding bitstream and know it's width/height.
