Package: i965-va-driver
Version: 1.0.16-4
Hi!
The description tells us that H.264 should be somewhat
supported. However, there's no such profile:
gfx@intel-gfx-test:/tmp$ vainfo
libva: VA-API version 0.32.0
libva: va_getDriverName() returns 0
libva: Trying to open /usr/lib/i386-linux-gnu/dri/i965_drv_video.so
libva: va_openDriver() returns 0
vainfo: VA-API version: 0.32 (libva 1.0.15)
vainfo: Driver version: Intel i965 driver - 1.0.16
vainfo: Supported profile and entrypoints
VAProfileMPEG2Simple : VAEntrypointVLD
VAProfileMPEG2Main : VAEntrypointVLD
If you build this driver from
git://anongit.freedesktop.org/vaapi/intel-driver, branch
g45-h264, we'd gain h.264 support (though the general
driver is a bit older, .14 instead of .16). However, this
would gain further profiles:
gfx@intel-gfx-test:/tmp$ vainfo
libva: VA-API version 0.32.0
libva: va_getDriverName() returns 0
libva: Trying to open /usr/lib/i386-linux-gnu/dri/i965_drv_video.so
libva: va_openDriver() returns 0
vainfo: VA-API version: 0.32 (libva 1.0.15)
vainfo: Driver version: Intel i965 driver - 1.0.14
vainfo: Supported profile and entrypoints
VAProfileMPEG2Simple : VAEntrypointVLD
VAProfileMPEG2Main : VAEntrypointVLD
VAProfileH264Baseline : VAEntrypointVLD
VAProfileH264Main : VAEntrypointVLD
VAProfileH264High : VAEntrypointVLD
It would be quite nice to have that additional acceleration
profiles available, even though if you'd ship an older version
of this VA driver. However, it be nice if you'd add two additional
patches then, which could be found in the Ubuntu package
(see
http://archive.ubuntu.com/ubuntu/pool/universe/i/intel-vaapi-driver/intel-vaapi-driver_1.0.15-1ubuntu2.debian.tar.gz).
These patches
are already on the GIT repo's master branch, but missing on
the (older) g45-h264 branch. The second one fixes an actual
assertion, while the first "only" adds the infrastructure used
by the second.
Thanks,
Jan-Benedict
