Hey there, I've got the same problem since today's upgrade from 72.0.3626.121-1 to 73.0.3683.75-1, on a NUC8I5BEH (also with intel video).
The workaround from https://bbs.archlinux.org/viewtopic.php?pid=1836760#p1836760 fixed it for me. vainfo output for this system is: | libva info: VA-API version 1.4.0 | libva info: va_getDriverName() returns 0 | libva info: Trying to open /usr/lib/x86_64-linux-gnu/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 | VAProfileH264StereoHigh : VAEntrypointVLD | VAProfileVC1Simple : VAEntrypointVLD | VAProfileVC1Main : VAEntrypointVLD | VAProfileVC1Advanced : VAEntrypointVLD | VAProfileNone : VAEntrypointVideoProc | VAProfileJPEGBaseline : VAEntrypointVLD | VAProfileJPEGBaseline : VAEntrypointEncPicture | VAProfileVP8Version0_3 : VAEntrypointVLD | VAProfileHEVCMain : VAEntrypointVLD | VAProfileHEVCMain10 : VAEntrypointVLD | VAProfileVP9Profile0 : VAEntrypointVLD | VAProfileVP9Profile2 : VAEntrypointVLD greetings, Uli
