Created attachment 142840 [details] 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: commit 55e7de7b193535133d4324e9f601ae44a0cdd9a7 Author: Boyuan Zhang <boyuan.zhang@amd.com> Date: Wed Oct 17 15:03:30 2018 -0400 radeonsi: enable vcn jpeg decode for raven Enable vcn jpeg decode for raven. Signed-off-by: Boyuan Zhang <boyuan.zhang@amd.com> Reviewed-by: Leo Liu <leo.liu@amd.com> 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 please?
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?
Hi Rafal, 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. Regards, Boyuan
Looks just like Bug 104597
Hey Boyuan, 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 :(
Created attachment 143704 [details] attachment-418-0.html Does the 'corrupted colors' situation improve if you start chromium with the following: allow_rgb10_configs=false chromium ?
