Radeon 4830 and vdpau

Hello,

I'm trying to make the x264 acceleration work on Radeon HD4830 with open-source drivers.

vdpauinfo gives this

Decoder capabilities:

name               level macbs width height
-------------------------------------------
MPEG1                 0 262144  8192  8192
MPEG2_SIMPLE          3 262144  8192  8192
MPEG2_MAIN            3 262144  8192  8192

As far as I can tell the support should be listed here. How do I troubleshoot this thing?

(I'm running with a HD 4890)

$ vainfo

The vdpau wiki page claims that h264 & VC1 should be supported, but that may be true only for newer cards.

This phoronix article mentions

"The patches implement UVD support for the AMD RV600 GPUs, the RS780/RS880, and the RV770/RV790. These patches go against the Radeon DRM kernel driver, which means the code won't be mainlined now until the Linux 3.18 kernel"

That suggests we may have to wait until kernel 3.18 .

I get the exact same output. Have no idea what it means though

Re: Radeon 4830 and vdpau

With kernel 3.18.2-2 and my aur mesa_*-git package VC1 and H264 are now working, so it seems we needed the kernel support.
