Hello, i updated the plex server on docker đ
and i still have really bad quality : (many artefacts )
Ubuntu 16.04 / Intel Core i7-2630QM (2.0 GHz) / HW transcoding activated and running
something to update ?

Sorry about that! đ
Thanks. I wonât need any additional information. The artifact problem is most likely due to the limitations of CPU/GPU.
To confirm I will need the XML of what youâre playing .

Can be fix with a futher version of VA-API driver or definately dead ?

Maxine,
When Intel releases 2.0.0 of `libvaapi`, POSSIBLY ??. Nothing is known until we can actually try it.
As per the artifacts youâre seeing. XViD is the issue. Itâs blocky to begin with and definitely not helping any. Hardware transcoding is making it worse. The bitrate is only 1.1 Mbps.

Thnaks. Itâs clearâŚ
1/ There is a way to test to test 2.0.0 of livaapi or itâs closed source ?
2/ There is a way, itâs the same issue for all linux user, to disable HW transcoding for all low biterate file ?
On hight biterate, it seems to working.
thnaks

I also just tried this new feature transcoding a HEVC video. It indeeds looks very badly, while with software transcoding it looks good. My cpu is a i3-2100, which is the first version that supports quick sync. I assume the quality was still suboptimal back then. Maybe they should just not allow it on that version.

Or you could turn off the option to use HW transcoding ?

i launched the autogen.sh and i have :
configure: error: Package requirements (libva \>= 1.0.0) were not met:
Requested âlibva \>= 1.0.0â but version of libva is 0.40.0
Something else to do ?

You will need to download libva 2.0.0.pre2 as well

Itâs the autogen file in the vaapiâs githup đ
Iâm trying to update vaapiâs driver in order to test if HW transcoding can be usefull on Linux server (my case)

vaapi 2.0.0pre is **untested** with PMS. Nothing can be done with it until official release.

Updating libva, vaapi and vainfo is outside the realm of Plex. You will be better off suited to ask how to on the Ubuntu support forums.

In a past thread it was pretty clear that these artifacts are indeed a Linux limitation: a user tried with the very same hardware and PMS in Windows and Linux, Windows was clear, Linux was blocky. Sadly it seems we are left to wait until thereâs an update of the libraries.
