Does it happen only with glimagesink or with videoconvert ! xvimagesink too ?
What are the caps negotiated between vaapih264dec and glimagesink ?

it is only with glimagesink and with this sample (other media files work OK).
It is dmabuf negotiated.

Ok, this is what I had in mind. This is tiled/compressed video displayed as if
it was linear. It also means that the DMABuf uploaded in glupload failed and it
had falledback to raw uploader. It means the code to ensure that exported
DMABuf are linear is broken. This is a problem we get in various scenarios with
recent Mesa.

Shall we fail in glupload if DMABuf capsfeature has been chosen and dmabuf
uploaded failed ?

I have seen similar issues for some specific resolution videos when playing
with gst-msdk plugins and glimagesink when negotiating dmabuf.

Is this the same issue we discussed multiple times in different bugs and IRC ?
"Using vaapipostproc after vaapih264dec fix the issue when using glimagesink in
dmabuf mode and egl platform"
