[0x94a6d10] avcodec decoder: Using VA API version 0.32 for hardware decoding.

the film starts with a lot of screen crash, jumps, big pixels and CPU at 130% Intel(R) Atom(TM) CPU D510 @ 1.66GHz (dual core HT). The computer have an ION2 GPU. Mplayer and XBMC play the same file without problems (and cpu at 20%), but i really need VLC. I have check the GPU option in codec preferences. If i turn off this option, the film plays a little best (not 100% perfect) but of course the cpu is at 330% and litle jumps.

Only fail in 1080p films, in 720 works nice. Before 2.0.0 (no multithread) the 720 files makes cpu at 99% too. Please, help me.

All seems normal with such CPU. You can try to deactivate audio to see if that is better.

[juanmol]

but works fine with mplayer and xbmc

i can't understand ... i think vlc not see the gpu or ... don't know

[Rémi Denis-Courmont]

So you're told to test with audio disabled, and what you do? You provide x264 version (totally irrelevant for decoding) and FFmpeg version... ?!

hi
i installed "sudo apt-get install x264" and used
"x264 --crf 22 --profile main --preset medium --b-pyramid normal -o psp.264 yang.avi" but taking too much performance on my CPU, got my entire computer down,

do you have any way to do Hardware compression on my graphics card or other hardware without too much CPU performance?
how to install on ubuntu, i mean could you give me guideline?

thanks
myles
