OK, maybe that could be it.
I may be able to try progressive, but need to remember what to change...
Seems I can't test progressive with this h/w. I had a different card
last time I did it - trying the same now just segfaults.
Yeah, the problem is the hardware Nayan is testing on doesn't have an
UVD block. So he just uses the presentation pipeline to test VDPAU and
that uses a progressive video buffer.
Andy what did you do to switch to progressive and why does it fail? Just
changing the return value for PIPE_VIDEO_CAP_PREFERS_INTERLACED in
radeon_video.c should still work fine.
That's roughly what I did - initially I did it a line later so supports
got false as well.
re-testing with an unpatched mesa and return false after PREFERS I see
the same.
s/w decode mplayer or mpv will segfault - bt below. No asserts with
debug build of mesa.
Sometimes/depending on input file it doesn't instantly segfault brief
output is corrupt and I get 00s of VM faults.
