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 <a class="bz_bug_link bz_status_RESOLVED bz_closed" title="RESOLVED FIXED - gallium/st/va: change va max_profiles when using Radeon VCN Hardware" href="show_bug.cgi?id=109107">bug 109107</a> 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 <a class="bz_bug_link bz_status_RESOLVED bz_closed" title="RESOLVED FIXED - gallium/st/va: change va max_profiles when using Radeon VCN Hardware" href="show_bug.cgi?id=109107">Bug 109107</a> 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 :(</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
