<pre>Archlinux
Dell Latitude e7450

Broadwell HD Graphics 5500

mpv 0.27.0
mpv -hwdec=vaapi -vo=vaapi video.mkv no longer works with mesa 17.2. It shows a
black window. No video plays. Audio plays fine. App UI works fine. No problems
with mesa 17.1.9. It also affects chromium when it is patched to enable
hardware acceleration via vaapi.
No errors on dmesg, mpv and /sys/class/drm/card0/error
Bisected mesa and found that vaapi stopped working with commit
8ec5a4e4a4a32f4de351c5fc2bf0eb615b6eef1b
If I reverse the changes to brw_state_upload.c with HEAD 17.2, vaapi starts
working again.
