Libav and VA-API install in Fedora

[Daniel Vernon]

Hi,

Thanks for the reply.  I followed your instructions (installed "libva-utils"
and also "libva-intel-driver") and 
now vainfo is working and giving sensible output (copied below), so a step
in the right direction.

Unfortunately though I still have no "avdec_h264" or "vaapidecodebin":-

[synx at localhost /]$ gst-inspect-1.0 avdec_h264
No such element or plugin 'avdec_h264'

[synx at localhost /]$ gst-inspect-1.0 vaapidecodebin
No such element or plugin 'vaapidecodebin'


I then tried to check that the packages for those are installed:-

[synx at localhost /]$ sudo dnf install gstreamer1-libav
Last metadata expiration check: 0:00:18 ago on Mon 09 Sep 2019 22:53:46 BST.
Package gstreamer1-libav-1.16.0-1.fc30.x86_64 is already installed.
Dependencies resolved.
Nothing to do.
Complete!

[synx at localhost /]$ sudo dnf install gstreamer1-vaapi
Last metadata expiration check: 0:00:48 ago on Mon 09 Sep 2019 22:53:46 BST.
Package gstreamer1-vaapi-1.16.0-1.fc30.x86_64 is already installed.
Dependencies resolved.
Nothing to do.
Complete!


- Both packages appear to be installed already.  Please can anyone tell me
what else could be missing or wrong with my system?

Thanks,

Daniel Vernon
