vlc - hardware decode for H264 ?

Postby cybmole » 08 Oct 2009 10:20

can VLc be configured to use the freeMPC video decoder & thus use suitable graphics card hardware decode for H264 ?

I have MPCvideodec.ax registered on this PC & working with Zoom player ( where is does greatly reduce CPU usage) , but I can't see how to get it working with VLC - is it even possible ?

Maybe. Probably need to wait for ffdshow to support openCL though. See

What i did on my older windows2000 htpc:

In VLC i select: Tools->preferences->Video->Output:OpenGL video output.

Then i got treu graphics card hardwareacceleration for video to Monitor & my plasma tv(2nd monitor).

To select video quality: go to graphics card settings. (select preformance to play video good & smooth, select quality to give video max quality).
I see differences in graphics card settings. (so i choose the middle option high quality but fast enough to render on Nvidia 6100 chipset in Nvidia settings).
I also see the temperature of graphics card gpu jump from 34 to 67*celcius when select openGL video out in vlc.
So that must be true hardware acceleration. :lol:

Oh for audio i choose: portaudio.
Maybe that some vlc developers know a link that explains what VLC exactly does in OpenGL video output mode, but it sure rocks here. 8)

the rise in GPU temperature could be just because open GL is less efficient & so the card has to work harder.

a better measure is what happes to your cpu load. if your GPU is taking over decoding the H264 ( which I doubt) then your CPU load in task manager should be much lower ???

OpenGL doesn't support any video decoding accelerations.

Ok, a bit old topic. but....


....thanks VLC developers for adding GPU hardware acceleration support!
I really see a difference when playing h264 or vc1 video codec.

(in fact, if i reencode a mpeg2 file to h264&pcm avi file, then it looks more sharp).

A giant beer for the one who added gpu support in VLC 1.1.0.
