libva error [SOLVED]

[Caysho]

I keep getting a "You can’t post image, email or url links" message, which prevents me submitting this in a more coherent manner, even with "Do not automatically parse URLs" selected.
See attachment for logs and references.

Running new install of Ubuntu 18.04 with updates current as at 23/06/2018, with MythTV from Ubuntu PPA.
Hardware is a NUC7CJYH.

Seeing high CPU use, around 60% to 80% wen viewing both SD and HD content (e.g. h.264 1080p), sometimes higher, when hardware acceleration should be available.
Checked with Totem and VLC, both have CPU usage lower at around 20% and rendering is very smooth, so I figured MythTV is not using the hardware acceleration.

There is a debian bug [1] which describes an issue with libva1 to libva2 transition.
The above occurs with and without Wayland enabled as per [2].

It looks like the mythtv packages you have are built against the old libva libraries. You will need updated packages built against the newer libva

These URL's and a filename have been broken with two periods, as I am still getting the message about posting URL's.

The packages are from the Ubuntu MythTV PPA:
http://ppa..launchpadnet/mythbuntu/0.29/ubuntu bionic main

I came across this when searching for mythtv libva2:
https://ubuntu..pkgs..org/18.04/ubuntu-multiverse-i386/mythtv-common_29.1+fixes.20180414.329c235-0ubuntu3_i386.deb.html
which has a dependency on libva2

Tried the following:
1. Uninstalled mythtv
2. Deselected the PPA
3. Reinstalled mythtv from the Ubuntu multiverse repository

Played a video, but still got the same error in the syslog.

At step 1 above, I noticed it listed a set of packages that were not required, including a libva-drm1 (at least, I recall it had drm1 in the name).
So I uninstalled mythtv again, and this time did an autoremove as well.
Then reinstalled and played a video.

Video hardware acceleration now works, and CPU usage is now around 20%, in line with the other media players:

Hmm, that sounds like a problem with the PPA.

This is the standard PPA for Ubuntu -> https://launchpad.net/~mythbuntu/+archive/ubuntu/0.29

[Caysho]

That is the PPA I used.

I tried it again:
1. Removed the application,
2. Ran the autoremove
3. Reactivated the PPA for installation.
4. Ran the installation from the PPA

The good news is that acceleration is now working with the PPA.

This installation started from ubuntu-gnome 16.04 with mythtv 29 from the PPA, and was then updated to 18.04.
Seems not all the library references get updated during the upgrade, but I am not in a position to try replicating the process.
