Red Hat Bugzilla – Bug 1297276
mesa vdpau drivers are missing
Last modified: 2017-08-01 12:00:03 EDT
Description of problem: el7 has a quite recent mesa version but the vdpau drivers are not built. Any particular reason for this? Looking at the .spec file it appears that "with_vdpau" can be set to "1", and that the r300 drivers can be included: +%{_libdir}/vdpau/libvdpau_r300.so.1* It would be great to have hardware accelerated video playback for software that supports vdpau.
It isn't a major problem to enable these drivers.
I built mesa with the above changes with the following card: 01:00.0 VGA compatible controller: NVIDIA Corporation GT218 [GeForce 210] (rev a2) I installed the firmware and enabled reclocking according to: https://nouveau.freedesktop.org/wiki/VideoAcceleration/ the audio was a bit "stuttery" playing hidef h264. I tried reclocking with: nouveau.pstate=1 and trying a few values in: /sys/class/drm/card0/device/pstate with no improvements (mplayer, kodi, mythtv) As a comparison, using the 340.96 nvidia driver has smooth playback. I don't know the likelihood of this improving on el7, but am reporting the results regardless. I guess it would be interesting to try this hardware on fedora to see if the situation improved...
mesa vdpau drivers are part of mesa-vdpau-drivers rpm: rpm -ql mesa-vdpau-drivers /usr/lib64/vdpau/libvdpau_nouveau.so.1 /usr/lib64/vdpau/libvdpau_nouveau.so.1.0 /usr/lib64/vdpau/libvdpau_nouveau.so.1.0.0 /usr/lib64/vdpau/libvdpau_r600.so.1 /usr/lib64/vdpau/libvdpau_r600.so.1.0 /usr/lib64/vdpau/libvdpau_r600.so.1.0.0 /usr/lib64/vdpau/libvdpau_radeonsi.so.1 /usr/lib64/vdpau/libvdpau_radeonsi.so.1.0 /usr/lib64/vdpau/libvdpau_radeonsi.so.1.0.0
