This variant of intel-vaapi-driver is a backport of the ancient g45-h264 branch that used to be maintained by the intel-vaapi-driver team. As far as I know, the reason they don't maintain this branch anymore is that hardware accelerated h264 decoding on the G45 chipset was much too slow for 1080p video, as by default it only had 32MB of VRAM to work with. It so happens that the librebooted Thinkpad T400 has one of these G45-based iGPUs, with one change: the iGPU has 256MB VRAM available. Using this package and a `hwdec=vaapi' setting in ~/.config/mpv/mpv.conf, I enjoy smooth video playback and low CPU usage for 1080p video using mpv. --=-=-= Content-Type: text/x-patch Content-Disposition: inline; filename=0001-gnu-Add-intel-vaapi-driver-g45-h264.patch Content-Description: [PATCH] gnu: Add intel-vaapi-driver-g45-h264. >From 8727588a6bca185f17480efc7327774b041e240d Mon Sep 17 00:00:00 2001 From: Jelle Licht Date: Wed, 27 Nov 2019 16:16:47 +0100 Subject: [PATCH] gnu: Add intel-vaapi-driver-g45-h264. * gnu/packages/video.scm (intel-vaapi-driver-g45-h264): New variable. --- gnu/packages/video.scm | 29 +++++++++++++++++++++++++++++ 1 file changed, 29 insertions(+) diff --git a/gnu/packages/video.scm b/gnu/packages/video.scm index 9836f67386..5eb0c7175f 100644 --- a/gnu/packages/video.scm +++ b/gnu/packages/video.scm @@ -2787,6 +2787,35 @@ post-processing of video formats like MPEG2, H.264/AVC, and VC-1.")
