Mesa 19.2.8 and VAAPI - bob -> only half screen picture for 1080i H.264

This is supposed to be fixed in Mesa 20.1 git by c81aa15d, gallium/auxiliary/vl: fix bob compute shaders for deint yuv.
See:
https://gitlab.freedesktop.org/mesa/mesa/-/commit/c81aa15d646215eac38c8e0b6dc1a10b35bc13c3

This could be backported to Mesa 20 if someone wants to try it.

Thank you Joseph.
As I written in first post, 20.1 git is ok here, tested from: https://launchpad.net/~oibaf/+archive/ubuntu/graphics-drivers
How can I test more, how to do to push the oibaf compil to ubuntu repository ?

Hi? no news ?

I've just try Focal fossa with new 20.0.2-1ubuntu1
Same problem, half screen picture for VAAPI - bob

let upstream know that the fix is needed in 20.0.x.. that way focal will get it (and bionic too, when mesa is backported for 18.04.5)

ok. please notice that https://launchpad.net/~oibaf/+archive/ubuntu/graphics-drivers is working fine

How to inform upstream (where) ?

Oibaf is using the development release of Mesa. It's not released yet. Mesa 20.1 isn't scheduled for release until May.

You need them to backport the fix to the 20.0.x branch. Here is the upstream issue: https://gitlab.freedesktop.org/mesa/mesa/issues/2523

You can ask there for a backport to 20.0.x.

Ok for Mesa 20.1
Concerning Gitlab, I can't send them a fix, I'm not a developer.
I'm still available for testing.
I will tell them for the bug with 20.0.2-1ubuntu1 and my hardware

No one is asking you to send them a fix. Since you are experiencing the issue on a stable release, you should let Mesa know that the issue exists in stable releases, and ask them to provide the fix for the stable 20.0.x branch.

Posted today, just after your post. Thanks

Nothing is changing. At this rythm, I think Focal Fosa will go out WITH the bug..

I've just tested latest mesa 20.0.4-1ubuntu1 for focal fossa
Bug is STILL present

it'll be fixed in 20.0.5

I've just tested focal fossa proposed 20.0.4-2ubuntu1 , It's working for this (my) bug.
I've tested it on live usb stick, but my computer is under Ubuntu 18.04 (see first post)
When can we expect proposed for Bionic ?

thanks for testing

the backport is provided after the last upstream bugfix release of 20.0.x series is out, so roughly in June

wow so long ....

It's half fixed, but NOT for my bug posting (I am on Ubuntu 18.04 and compilation for it is MISSING)

I had time today to test 20.0.4-2ubuntu1~18.04.2 proposed bionic
It's working , wow what a long stuff..
Happy end

Proposed is out at may the 27th. When can we expect the release ?

not before the last of the series, 20.0.8, is tested.. I'll upload it today

Ok.

I've just tested the proposed bionic 20.0.8-0ubuntu1~18.04.1. It's working for my bug. Hope we get release soon now :) As you know bionic is under LTS support until 2023..

Still nothing for bionic ?
