h.264 decoding

Post by fenris » Fri May 30, 2008 21:16

Is there really no h.264 hardware decoding support for linux? Is it the display- drivers that's the problem here, or..

Hi! I can't tell if there is native support for h264 decoding by the graphic card on Linux or not, but one thing I know. When you play a video file encoded in h264 in mplayer, you can choose to render it with opengl, witch is done by the graphic card. I notice a great drop in the CPU usage when it is done by opengl. So, what I mean is, even is the drivers are not using the decoding feature of your graphic card, there is indeed use of the graphic card in the decoding process, trough opengl rendering.

Thanks. I installed an opengl gstream plugin, and that seems to work. It won't handle hd video all that well, but it works for everything else. :)

The xine engine won't start, for some reason, reporting something about..
"libx264.so.59: cannot open shared object file". Any ideas?

..seems I can run the high def video without any trouble after all with the xine engine (it's about 30% load, used to be 100%). Hm. No idea if I did anything specific to make it work, though..
