I was able to get a 1080P MKV (avc1?) accelerated on Windows XP SP3 with DXVA...needless to say I was pretty pumped given that the Vista install with this card and Nforce3 would lock up my system.....
I watched Elephant's Dream with DXVA, cpu 15% during major action, and w/o DXVA enabled in Cyberlink....cpu 100%....unwatchable.
1. I need to figure out how to check the encoding options used on existing MKV files I have. Will try this:
"there is a quicker way to get the encoding options used in any container (mkv, mp4, avi, etc). Just download and install AVInaptic. (The first time you run it click on the box that says "Italiano" to select English as the language.)"2. I need to remove DirectVobSub from the filter chain; do I need to uninstall it completely?
3. I'll post encoding options for my backups that do HA here:
"I played a file with the following encoding options:
Code:
string is ".E....H..,. .#..x264 - core 56 svn-676 - H.264/MPEG-4 AVC codec -

You can see the encode uses most of the advanced encoding options: CABAC, 5 reference frames, B-frame RDO, mixed reference frames, adaptive 8x8 transforms (High Profile), 3 B-frames, B-frame pyramids, and adaptive b-frames. I was expecting one of those options to be the trigger to make DXVA fail, but apparently not.
DXVA worked with the following video renderers (I checked the input pin on the renderer, which showed "DXVA 1280x528 23.98fps"):
Overlay Mixer
VMR7 (Windowed)
VMR7 (Renderless)
VMR9 (Windowed)
VMR9 (Windowless) (ZP only)
VMR9 (Renderless), plain offscreen, 2D & 3D Surfaces
EVR (using .NET 3.0, MPC HC only)
DXVA did NOT work with the following video renderers (I checked the input pin on the renderer, which showed "RGB 1280x528 23.98fps" or "YUY2 1280x528 23.98fps"):
Haali Video Renderer
Nero Video Renderer
DXVA did NOT work with the CoreAVC or MainConcept H.264 decoders (despite "HA" set to "on" for the MainConcept decoder)."
