Hi,
first of all: Thanks a lot for putting effort into this sort of ancient
hardware, I'm really surprised in a very positive way to see open source
UVD support happen on old R600 GPUs. I gave the recently posted patches
a shot an here is my first impression:
Kernel from uvd-r600-release branch compiles and boots fine
(I also included the 3.16.1 and Con Kolivas' ck/BFS patch as well, I
hope that was OK; I could give it a try without modifications as well,
if that would help.)
Mesa with the posted patch applied also compiled fine
First tests with mplayer were not so successful, unfortunately:
I tried "big buck bunny" with both software and hardwarde decoding.
Software looks OK (as expected). Hardware decoding seems to work,
mplayer doesn't complain and CPU usage also goes down significantly, the
resulting image is distorted, however.
I tried to get a screen shots to illustrate the issue, see attachment.
Looks like part of the top is found at the bottom, and look sort of like
an interlaced image.
Sounds like you're missing
http://cgit.freedesktop.org/mesa/mesa/commit/?id=80771e47b6c1e47ab55f17311e1d4e227a9eb3d8
.
Agree, that is exactly the expected behavior if you don't use the
necessary mesa patch.
Please make sure you actually installed mesa into the correct path etc....
Christian.
