MPEG4 AVC accelerated playback

thymej · 9th May 2008, 04:51

Can ffdshow be configured to use the hardware acceleration in my nVidia 9600GT video card? If not what would be your suggestion for a h.264 codec that utilizes hardware acceleration (A free GPL/openSource/etc codec)? I know about WinDVD and PowerDVD, I'm looking for a free codec that uses the purevideo acceleration.

Use MPC-HC's internal DXVA mode. It should do what you want.

I will have to test MPC-HC. So it has a built in h.264 avc codec that support hardware acceleration?

And remember that your AVC files might have to be "compatible" with DXVA. Read http://forum.doom9.org/showthread.php?t=132924.

MPC-HC worked for me. Better then I thought it would considering without DXVA I was at 50% both cores each. With DXVA I get 2% on each core.

Now if only the internal codec to MPC-HC was a standaolne so it could be used in ZoomPlayer.

Now I just need to find a DXVA codec that works in ZoomPlayer

Found it, thanks.

I downloaded it, installed it, and tested it. It works as it does in MPC.

But, it was hit and miss on the MP4, MKV, etc files I have tried. The files that did not work with DXVA under XP were black screens and just the first frame or so would display.

I'm an XP user so this last week I installed Vista in duel-boot mode and now with DXVA2, almost all of my x264 file use DXVA. The few x264 files I have that worked in XP, MPC showed missed frames during playback but it was still watchable. In vista I get 0 missed frames using EVA.

Thank everyone.

Check (with MediaInfo) if your encodes are 5 Ref Frames or more (that is associated with this symptom).
Over here (nVidia 8600 GTS) only the 4 Ref Frames or less works fine with MPC-HomeCinema (or the MPCVideoDec.ax decoder).
