Created attachment 458138 [details] emerge --info output Hello, I'm running stable gentoo on broadwell system without x11-drivers/xf86-video-intel, using modesetting_drv.so, works great. VIDEO_CARDS="i965" I noticed that mpv does not provide hw acceleration despite everything compiled with vaapi support. vainfo libva info: VA-API version 0.38.1 libva info: va_getDriverName() returns 0 libva info: Trying to open /usr/lib64/va/drivers/i965_drv_video.so libva info: va_openDriver() returns -1 vaInitialize failed with error code -1 (unknown libva error),exit tried to search for i965_drv_video.so and it definitely was missing from my system. Installing libva-intel-driver solved my problem vainfo # after installing libva-intel-driver libva info: VA-API version 0.38.1 libva info: va_getDriverName() returns 0 libva info: Trying to open /usr/lib64/va/drivers/i965_drv_video.so libva info: Found init function __vaDriverInit_0_38 libva info: va_openDriver() returns 0 vainfo: VA-API version: 0.38 (libva 1.6.2) vainfo: Driver version: Intel i965 driver for Intel(R) Broadwell - 1.6 vainfo: Supported profile and entrypoints VAProfileMPEG2Simple : VAEntrypointVLD VAProfileMPEG2Simple : VAEntrypointEncSlice VAProfileMPEG2Main : VAEntrypointVLD VAProfileMPEG2Main : VAEntrypointEncSlice VAProfileH264ConstrainedBaseline: VAEntrypointVLD VAProfileH264ConstrainedBaseline: VAEntrypointEncSlice VAProfileH264Main : VAEntrypointVLD VAProfileH264Main : VAEntrypointEncSlice VAProfileH264High : VAEntrypointVLD VAProfileH264High : VAEntrypointEncSlice VAProfileH264MultiviewHigh : VAEntrypointVLD VAProfileH264MultiviewHigh : VAEntrypointEncSlice VAProfileH264StereoHigh : VAEntrypointVLD VAProfileH264StereoHigh : VAEntrypointEncSlice VAProfileVC1Simple : VAEntrypointVLD VAProfileVC1Main : VAEntrypointVLD VAProfileVC1Advanced : VAEntrypointVLD VAProfileNone : VAEntrypointVideoProc VAProfileJPEGBaseline : VAEntrypointVLD VAProfileVP8Version0_3 : VAEntrypointVLD VAProfileH264MultiviewHigh : VAEntrypointVLD VAProfileH264MultiviewHigh : VAEntrypointEncSlice VAProfileH264StereoHigh : VAEntrypointVLD VAProfileH264StereoHigh : VAEntrypointEncSlice I think VIDEO_CARDS="i965" should make libva depend on libva-intel-driver as well. let me know if you need more information about the system.
libva pulls libva-intel-driver with VIDEO_CARDS=intel. Is it not enough?
VIDEO_CARDS=intel is not enough. it's wrong in some cases. let me explain. I'm not running some experimental unsupported configuration, modesetting is the preferred driver for my card according to upstream. I switched to modesetting because I was having crashes and deadlocks with classic intel driver. VIDEO_CARDS=intel pulls xf86-video-intel and many other intel related stuff into system for various packages. As of xorg-server-1.17, the modesetting driver was moved into x11-base/xorg-server. This driver has more features than the classic intel driver, such as GLAMOR. Beginning with x11-base/xorg-drivers-1.19, x11-base/xorg-drivers also includes the video_cards_i965 USE flag. This will omit x11-drivers/xf86-video-intel in favor of the more advanced modesetting driver built in to x11-base/xorg-server. here are 2 lines from x11-base/xorg-drivers-1.19 ebuild video_cards_i965? ( >=x11-base/xorg-server-${PV}[glamor] ) video_cards_intel? ( !video_cards_i965? ( x11-drivers/xf86-video-intel ) ) Other distros have started phasing out xf86-video-intel in favor of the modesetting driver which the latter is more advanced on Gen 4 and later Intel GPUs So some people moving from intel driver to modesetting, and libva ebuild should support that. Some information taken from here. https://wiki.gentoo.org/wiki/Talk:Intel All that information makes me believe that libva ebuild should definitely support video_cards_i965 and pull x11-libs/libva-intel-driver. Currently it's counter-intuitive and a user has to install libva-driver manually, which is not expected behavior with correctly set USE flags and VIDEO_CARDS variables.
