Using Kodi to watch tv using the HTSP plugin, using VDPAU for decoding:
kodi.bin: ../mesa-18.2.0-rc4/src/mesa/state_tracker/st_sampler_view.c:546:
st_get_texture_sampler_view_from_stobj: Assertion `stObj->level_override ||
last_level(stObj) == view->u.tex.last_level' failed.

VAAPI decoding works.

mpv.conf triggering the issue

This also appears when trying to watch videos in mpv with the OpenGL video
output using VDPAU hardware decoding and the VDPAU post processing filter. The
video does not play and the failed assertion is thrown to the command line.
Interestingly, hardware decoding using VDPAU without activating the post
processing filter does not hit the failed assertion.

I am using a Radeon RX 580 with a recent git mesa (commit
3a95396f3c6f51d38f044375bbd6698ed6cb28f4), a pretty recent LLVM 8 version and
kernel 4.18.14.

The issue can be reproduced by trying to play the video linked in [1] with mpv
(with youtube-dl support) and the attached mpv configuration. When I comment
out the line containing vdpaupp, the video starts to play.
