Screenshot for Chromium with corrupted video
When playing video on YouTube using Chromium I see broken colors.
Info from the YouTube player:
Codecs vp09.00.51.08.01.01.01.01 (247) / opus (251)
Color bt709 / bt709
I experience this problem on two machines:
1) HP EliteBook 745 G5 with Ryzen 5 PRO 2500U
It runs 1.03.01 BIOS with 0x0810100b CPU microcode.
2) MateBook D with Ryzen 5 2500U
It runs 1.12 BIOS with 0x08101007 CPU microcode.
I've bisected the *fix* down to the:

Is that possible to either:
1) cherry-pick those vcn/va fixes to the 18.1 and 18.2 branches
2) disable unsupported formats support in the 18.2 and 18.2 branches
The announcement on Mesa 3D webpage says:
> NOTE: It is anticipated that 18.2.8 will be the final release in the 18.2 series. Users of 18.2 are encouraged to migrate to the 18.3 series in order to obtain future fixes.
So I guess nobody will care about cherry-picking those fixes? Should this just get closed? Boyuan could you comment on this?
First of all, sorry for getting back to you late. I somehow missed this message.
I took a look of your reported issue, but I got a little it confused here. So you saw color corruptions when playing a VP9 video using Ryzen 5 PRO 2500U (raven vcn), and you found that the "enable vcn jpeg deocde" patch/patch set can actually fix the VP9 color corruption, is that what you mean? I'm a bit confused why jpeg patch could affect VP9 decoding. Or did I misunderstand here? Please help me to clarify.
And it seems that there is no vcn jpeg decode support in 18.1 and 18.2 branch. I believe that vcn jpeg decode has been added to 18.3 branch.
Looks just like Bug 104597
thanks for looking at this issue! I agree it's quite confusing, but I finally found out what's going on.
Let me provide a new summary of Mesa releases & this problem:
1) Accelerated VP9 decoding in Chromium is broken with 18.1 & 18.2.
2) Video Acceleration DOESN'T WORK in Chromium with 18.3.0 - 18.3.3
3) Accelerated VP9 decoding in Chromium is broken with 18.3.4 & 19.0.
By "broken" I mean corrupted colors.
Earlier confusion was due to the commit 55e7de7b1935 ("radeonsi: enable vcn jpeg decode for raven") EXPOSING a bug 109107 which was related to reporting profiles. That commit STOPPED Chromium from using Video Acceleration and made it report following errors:
[21202:21202:0317/122002.223002:ERROR:vaapi_wrapper.cc(587)] : vaQueryConfigProfiles returned: 14
[21202:21202:0317/122002.223045:ERROR:vaapi_wrapper.cc(587)] : vaQueryConfigProfiles returned: 14
Bug 109107 got fixed with the commit 21cdb828a3f4 ("st/va: fix the incorrect max profiles report") and since then:
1) Chromium uses Video Acceleration again
2) I see corrupted VP9 YouTube colors again
So the commit 55e7de7b1935 ("radeonsi: enable vcn jpeg decode for raven") DIDN'T FIX anything but has only hidden the original problem. It stopped Chromium from using Video Acceleration including VP9 hardware decoding.
The problem is still there (in the 18.3.4, 19.0 and master) and needs to be fixed :(

Does the 'corrupted colors' situation improve if you start chromium with
