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 - https://lists.freedesktop.org/archives/mesa-dev/2016-July/124695.html Filing bug/test to see if anyone else reproduce. ________________________________ You are receiving this mail because: * You are the QA Contact for the bug. * You are the assignee for the bug.
