Subject: st/va: also honors interlaced preference when providing a video format
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=bf901a2f8c8954e55a3eebc6cd1b725f18802012;p=mesa.git

st/va: also honors interlaced preference when providing a video format

This fixes a crash when using the prefered video format with vaapisink
on Nvidia hardwares.
Also caught by the following assert:
  nouveau_vp3_video.c:91: Assertion `templat->interlaced' failed.

TEST= gst-launch-1.0 videotestsrc ! video/x-raw, format=NV12 ! vaapisink
