OpenMAX is currently embedded-centric, and it is not clear that it would spread to desktops. Has anyone got this working with 0.9.8a? Doesn't work for me.
I've been trying to achieve x264 hardware acceleration ever since I got my laptop last year, have tested dozens of players, and VLC would systematically yield the best playback results. To conclude, I think the PureVideo label (if not the technology) has contributed so much fudge to this topic that people have been thrown off-track. My guess is that when VLC is forced to use DirectX, then it accesses the DXVA function (v1 under XP does provide hardware acceleration). I would like the community to confirm my findings : I have only tried this with SD (720x576/PAL) content because that's all I have. 3.1 boot my laptom, play a video with VLC - GPU-acceleration is ON (near-zero CPU)ģ.2 play it with another player (MPC-HC for instance) - no GPU acceleration (CPU > 20%)ģ.3 close other player and play again with VLC - no GPU acceleration (CPU > 20%)ģ.4 reboot or go to standby & back - GPU-acceleration is ON.
I have found no acceleration if it is set to "Direct3D" (or any other module) VLC accelerates playback if the "Output Module" is explicitly set to "DirectX", not to "Default"Ģ. My statement needs some qualification however : How do I know ? I get near-zero CPU usage, as opposed to 10-30% CPU usage when not accelerated. Well, I encode my SD videos with x264 and VLC plays it back with hardware acceleration.

Nvidia users will recall that series 6- and 7- GPUs provide partial H.264 acceleration, while series 8- and over provide acceleration of all H.264 functions (notice I explicitly avoid the highly confusing "PureVideo" term).
I found that VLC 0.8.6* does achieve hardware acceleration of x264-encoded streams on my Nvidia GeForce Go7300, in WindowsXP SP2.
