That's indeed even simpler than my -va hwaccel proposal. However, your  
patch will prefer the non-accelerated codec for VOs that implement  
that case. i.e. it probably would be better to add the accelerated  
pix_fmt first. But for non-accelerated outputs, the default  
get_format() will only get the first pix_fmt[]. In my local tree, I  
have added an IS_VDPAU_PIX_FMT() macro to filter out accelerated  
pix_fmts in that function.

(BTW, you'd also need my patch for vd_ffmpeg as this code will  
actually crash for H.264)
