xf86-video-nv supported it, and I added it to nouveau as well when I ported YUV plane support. Some video players use the Xv property when available. https://cgit.freedesktop.org/xorg/driver/xf86-video-nv/tree/src/nv_video.c#n128 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/gpu/drm/nouveau/dispnv04/overlay.c?h=v4.15-rc3#n316 Cheers, -ilia _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel
