This is going to be a really crappy bug report and I apologize for that in advance. A client has a remote system which is Intel NUC8i5BEK with Coffee Lake running Fedora 29 (5.0.7-200.fc29.x86_64) Mesa 18.3.6 with chromium-vaapi 73.0.3683.103-1.fc29 (https://admin.rpmfusion.org/pkgdb/package/free/chromium-vaapi/): libva info: VA-API version 1.4.0 libva info: va_getDriverName() returns 0 libva info: Trying to open /usr/lib64/dri/i965_drv_video.so libva info: Found init function __vaDriverInit_1_4 libva info: va_openDriver() returns 0 vainfo: VA-API version: 1.4 (libva 2.4.0) vainfo: Driver version: Intel i965 driver for Intel(R) Coffee Lake - 2.3.0 vainfo: Supported profile and entrypoints VAProfileMPEG2Simple : VAEntrypointVLD VAProfileMPEG2Simple : VAEntrypointEncSlice VAProfileMPEG2Main : VAEntrypointVLD VAProfileMPEG2Main : VAEntrypointEncSlice VAProfileH264ConstrainedBaseline: VAEntrypointVLD VAProfileH264ConstrainedBaseline: VAEntrypointEncSlice VAProfileH264ConstrainedBaseline: VAEntrypointEncSliceLP VAProfileH264Main : VAEntrypointVLD VAProfileH264Main : VAEntrypointEncSlice VAProfileH264Main : VAEntrypointEncSliceLP VAProfileH264High : VAEntrypointVLD VAProfileH264High : VAEntrypointEncSlice VAProfileH264High : VAEntrypointEncSliceLP VAProfileH264MultiviewHigh : VAEntrypointVLD VAProfileH264MultiviewHigh : VAEntrypointEncSlice VAProfileH264StereoHigh : VAEntrypointVLD VAProfileH264StereoHigh : VAEntrypointEncSlice VAProfileVC1Simple : VAEntrypointVLD VAProfileVC1Main : VAEntrypointVLD VAProfileVC1Advanced : VAEntrypointVLD VAProfileNone : VAEntrypointVideoProc VAProfileJPEGBaseline : VAEntrypointVLD VAProfileJPEGBaseline : VAEntrypointEncPicture VAProfileVP8Version0_3 : VAEntrypointVLD VAProfileVP8Version0_3 : VAEntrypointEncSlice VAProfileHEVCMain : VAEntrypointVLD VAProfileHEVCMain : VAEntrypointEncSlice VAProfileHEVCMain10 : VAEntrypointVLD VAProfileHEVCMain10 : VAEntrypointEncSlice VAProfileVP9Profile0 : VAEntrypointVLD VAProfileVP9Profile0 : VAEntrypointEncSlice VAProfileVP9Profile2 : VAEntrypointVLD I'm locally running a system with an exact same version of software (kernel, Mesa, chromium-vaapi), except locally it's Dell Precision 7510 with Skylake GT2. ***** Coffee Lake fails to play VP9 videos in Chromium & YT entirely. Skylake plays VP9 videos in Chromium & YT no problem. ***** The issue seems to have popped up somewhere between kernel 5.0.4 and 5.0.6 and continues in 5.0.7. Again, I apologize for vagueness and lack of detail.
This looks like a vaapi driver issue. The vaapi driver is located on github : https://github.com/intel/intel-vaapi-driver I would recommend filing an issue there. You can use this bugzilla for kernel or Mesa related issue. Thanks!
