<p>Hi !</p>
<p>I'm struggling to get VDPAU HW acceleration with VLC and OSS radeon driver on a Radeon HD6250 (r600).</p>
<p>I'm testing latest VLC git (which include VDPAU pass-through by Rémi Denis-Courmont) on an Ubuntu Raring 13.04 system, with kernel 3.10 from Saucy (13.10) repository and a couple of PPA for git versions of MESA-Xorg bits and libav (previously also testing on an Archlinux system).</p>
<p>From dmesg and Xorg log all seems OK and vdpauinfo told me:</p>
<p>#> export VDPAU_DRIVER="r600"<br>

<p>In particular, the error:<br>
[0xb5e0cb00] vdpau_display vout display error: source video YCbCr format not supported</p>
<p>seems to suggest that my card cannot handle my video colorspace (it's I420/YV12), which in fact doesn't show up in vdpauinfo as well ... but then, why mplayer can play the same video with the same card throught VDPAU without any hiccups ? Where I'm missing something ?</p>
<p>If more logs or info are needed, just ask me. </p>
<p>Forgive me, if I was a bit (too) verbose :-) Thanks to all !</p>
