Bug ID: 97261
Summary: vaapi u/v wrong order since vl/util: add copy func for
yv12image to nv12surface
Product: Mesa
Version: git
Hardware: Other
OS: All
Status: NEW
Severity: normal
Priority: medium
Component: Mesa core

small test vid
As noted st the time, though Boyuan said he couldn't reproduce, for me
vl/util: add copy func for yv12image to nv12surface
gets u and v for both yv12 and I420 inputs reversed whether encoding or
playing.
Both gstreamer and mpv affected.
Testing playback using attached small test vid that instantly shows the issue
either
VAAPI_DISABLE_INTERLACE=true mpv --vo=vaapi uvtest.mkv
or
gst-launch-1.0 filesrc location=uvtest.mkv ! matroskademux ! avdec_h264 !
vaapisink
Of course any test that outputs nv12 works OK as it avoids the conversion.
It seems that the new util function expects input to be yuv, but it actually
gets yvu.
I sent a patch to the list for this -

Filing bug/test to see if anyone else reproduce.
