 Posted: Thu Jul 17, 2014 2:06 am Post subject: problems with radeon r300 + vdpau: libvdpau_r300.so missing |
 |
|
Hi,
I decided to try video acceleration on my now 8+y old laptop to view modern video files.
The graphics chip is a Radeon Mobility X700 (RV410).
From the radeon wiki i assume that this chipset should be able to use vdpau api using the radeon r300 gallium driver.
According to this howto
http://wiki.gentoo.org/wiki/VDPAU
and regular gentoo workflow everything should work, however the vdpau/r300-"linking"-library libvdpau_r300.so is missing.
| Code: | # emerge -pv mesa libvdpau libva xf86-video-ati xorg-server
These are the packages that would be merged, in order:

From vague guessing, I expected libvdpau to create that library. However, it's not there. I even enabled the dummy video card to check that it's not a problem specific to my radeon card/driver.
What Package is supposed to create that file? What use-flag or configure option do I lack?
During mesa configure, I happened to see the following:
| Code: | prefix: /usr
exec_prefix: ${prefix}
libdir: /usr/lib
includedir: ${prefix}/include
OpenGL: yes (ES1: no ES2: no)
OpenVG: no
OSMesa: no
DRI drivers: no
DRI driver dir: ${libdir}/dri
GLX: DRI-based
EGL: yes
EGL platforms: x11 drm
EGL drivers: builtin:egl_glx builtin:egl_dri2
llvm: yes
llvm-config: /usr/bin/i686-pc-linux-gnu-llvm-config
llvm-version: 3.3
Gallium: yes
Target dirs: dri-swrast r300/dri
Winsys dirs: radeon/drm sw sw/dri
Driver dirs: galahad identity llvmpipe noop r300 rbug softpipe trace
Trackers dirs: dri vdpau xa xvmc
Shared libs: yes
Static libs: no
Shared-glapi: yes |
It states "DRI drivers no", however i actually want video accel and assumed it's there.
I furthermore retried quite some steps using the xvmc use flag - it's stated in some related forum posts - but it didn't help.
Any hints for me? |

| So nobody even has an idea what package should create libvdpau_r300.so ? |

VDPAU support for r300g has been added again (by commit b7186ebea996072ed519ebae3fac8210941ce607 ) . Feel free to test mesa-9999  |
