vaapi decoded video doesn't display correctly in glimagesink

When running the following pipeline:

gst-launch-1.0 -vvv videotestsrc ! vaapih264enc ! vaapih264dec ! glimagesink

the resulting video looks like this:

Screenshot_from_2020-06-01_18-28-28

It's the same result for vaapih265dec, vaapivp8dec, and vaapivp9dec.

Other sinks, such as vaapisink and xvimagesink, render correctly.

I get the same problem in an OpenGL app using an appsink like this: vaapih264dec ! glupload ! appsink.

The pipeline is negotiating video/x-raw(meta:GstVideoGLTextureUploadMeta) between the decoder and the glupload.

Happening with:

  • Fedora 32 64bit
  • gstreamer1-1.16.2-2
  • gstreamer1-vaapi-1.16.2-1
  • libva-intel-driver-2.4.0-3

Was not a problem previously on Fedora 30 with:

  • gstreamer1-1.16.0-1
  • gstreamer1-vaapi-1.16.0-1
  • libva-intel-driver-2.4.0-1
