Little help with VAAPI

I am compiling gstreamer by source... trying to get VAAPI to work.

when I run gst-inspect-1.0 | grep vaapi nothing shows.

I have successfully compiled gstreamer-vaapi-1.12.3 and all its other base and plugins.

Where do I go look to see why vaapi is not getting detected when compiling?

I see that libav compiles with --disable-vaapi ???

so I tried to add --enable-vaapi but it says UNKNOWN option.

How do I get vaapi compiled in gstreamer ?

THanks,

Jerry

Re: Little help with VAAPI

Hi Jerry,

Yes it is a little confusing...

First make sure the vaapi interface is working by running 'vainfo'

Then if you have compiled and installed gstreamer-vaapi repository you
should see the library in $PREFIX/gstreamer-1.0/libgstvaapi.so

If the library seems to be in the right place, you can force GStreamer
to rebuild its registry: rm -f ~/.cache/gstreamer-1.0/registry*

Actually, libav have nothing to do with vaapi. They both provide
encoders and decoders but libav is software based whereas vaapi use
hardware capabilities.

Thanks, Pascal

Re: Little help with VAAPI

Nope it is not looking good...

Do you have /usr/lib64/dri/i965_drv_video.so ???

If not it seems that you need to install
package xorg-x11-drv-intel.x86_64

Re: Little help with VAAPI

Ok, for sure you need the intel driver.

But I am not so sure if vaapi can work while still using the
default kms driver. You can try to enable intel driver like this:

cat /etc/X11/xorg.conf.d/20-intel.conf
Section "Device"
Identifier "Intel Graphics"
Driver "intel"

Confirm before and after the change by checking
/var/log/Xorg.0.log

Re: Little help with VAAPI

So I created the 20-intel.conf file and rebooted.

[ 18.048] ABI class: X.Org Video Driver, version 24.0
[ 18.048] (II) intel: Driver for Intel(R) Integrated Graphics Chipsets:
i810, i810-dc100, i810e, i815, i830M, 845G, 854, 852GM/855GM, 865G,
915G, E7221 (i915), 915GM, 945G, 945GM, 945GME, Pineview GM,
Pineview G, 965G, G35, 965Q, 946GZ, 965GM, 965GME/GLE, G33, Q35, Q33,
GM45, 4 Series, G45/G43, Q45/Q43, G41, B43
[ 18.051] (II) intel: Driver for Intel(R) HD Graphics
[ 18.051] (II) intel: Driver for Intel(R) Iris(TM) Graphics
[ 18.051] (II) intel: Driver for Intel(R) Iris(TM) Pro Graphics
[ 18.051] (++) using VT number 1

This is what I get now. So I think the Intel driver is loading.

However vainfo is still no go.

These are the files:

ls /usr/lib64/dri/
i915_dri.so i965_dri.so kms_swrast_dri.so nouveau_dri.so r300_dri.so r600_dri.so radeonsi_dri.so swrast_dri.so virtio_gpu_dri.so vmwgfx_dri.so

So I search for the file:

yum provides "*/*i965_drv_video.so"
Loaded plugins: fastestmirror, langpacks
Loading mirror speeds from cached hostfile
* base: ftp.ussg.iu.edu
* elrepo: ord.mirror.rackspace.com
* epel: ord.mirror.rackspace.com
* extras: ftp.ussg.iu.edu
* updates: ftp.ussg.iu.edu
No matches found

I am using CentOS 7.7
