<br></div>Looking at current GIT code, I'm pretty sure I don't see such fallback (VDPAU related code was moved to hw/vdpau directory and changed a lot since that time).<br><br></div>Since I'm using the OSS UVD enabled *radeon* driver, and output of vdpauinfo expose exactly this behaviour (only NV12 surfaces), I suspect this could be a problem.<br>
<br></div>In addition, since some commit around 2013-07-07 and on, now VLC tells me another thing:<br>[0xb5753158] avcodec decoder debug: available hardware decoder output format 53 (vaapi_vld)<br>[0xb5753158] avcodec decoder debug: available hardware decoder output format 109 (vdpau)<br>

<br>I don't mean to be harsh at all, I'm just willing to interact, to make it work in VLC also, since I fear there is just some little incompatibilities in *HOW* VLC try to use VDPAU, with OSS driver on AMD hardware.<br>

<p>Before forcing VDPAU as video output, I've already tried leave it to default "Automatic" and the option "Accelerated video output (Overlay)" is checked (the old option --ffmpeg-hw is not present anymore), but the result is that, after trying VDPAU it falls-back to xv, starting to skip pictures and the CPU load goes 100%: <br>

<br>
</div>VLC could render with VDPAU on your card, but it would require software<br>
conversion from I420 to NV12. You are better off using XVideo than VDPAU then.<br>
The only benefit of VDPAU would be finely scaled OSD, at the expense of<br>
performance in this case.<br>
<br>
In fact, it would work just fine like normal if you had not needlessly forced<br>
VDPAU as video output in your preferences. If you want to accelerate video<br>
*decoding*, there is dedicated option for that.<br>
