Re: VDPAU testing tool
Any FTA media is a maximum of 1920x1080 @ 60Hz interlaced, so 30 fps.
For any H264 content, it all depends on the complexity of the profile and same thing FTA is 30 fps max ; with a bluray being 24fps.
I don't know what h264 video he's using on his test, but it's very unlikely performance wouldn't vary based on the video being played.
Like a capture from a HD-PVR is extremely complex to decode and require a huge processor, yet VDPAU does it perfectly on even a 8400gs which is one of the slowest card available.
From what I've seen, decoding is never an issue in real life. All VDPAU cards seem to be able to handle any content. Deinterlacing is what make a big difference between cards.
