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.
