plain terminal output, gst-discoverer output

This bug report is about the 2020 remake/re-release of the game
Diggles/Wiggles. The game is available on Steam and GOG. I tested with the
GOG.com version (v2.1.1.10).

Description: the video file startup.mov should be played on game start but the
video doesn't work: only black screen is shown and there is no audio either.
Pressing <Esc> is skipping the unplayable video and the game loads the main
menu.

gst-play opens and plays the video properly.

Reverting commit
commit 2a0a43627b9bf3d2073e06322d651a827af64cc7
(winegstreamer: Implement MPEG-4 audio to wg_format conversion.)
fixes the problem and the intro video works properly.

As far as I know there is no demo version available.

Please let me know if you need debug logs.

My personal guess on helpful data would be that comparison of mfplat (and
gstreamer) logs in working and non-working state could offer some useful hints
on what went wrong...

Funny though that messing with audio nuked video...

I don't suppose you have the game on Steam? The video seems to be simply
skipped there for me...

Can you attach a log with +mfplat please?

It may also be worth testing

I don't have the game on Steam, sorry.

With MR5988 applied the first few frames of the video is played then the game
hangs indefinitely:

thread 0024, blocked by 0170, retrying (60 sec)

Hmm, are you sure that commit is the wrong one? It looks like it's breaking on
the video stream, not the audio stream...

Can you please add GST_DEBUG=6 to the log?

It looks like this failure may be specific to the nvdec plugins, and I don't
have a machine that has those...

You are probably right, it must be something with my 32-bit Gstreamer
installation, because each time I remove the Gstreamer cache file
'registry.i686.bin' before starting the game, the video file works properly.
When registry.i686.bin is already created the intro video works only with
commit 2a0a43627 reverted.

gdb output for conflicting threads

Just to leave a more permanent note about mr5988:

I've come across a case where that mr causes a critical section freeze that may
be related. Attaching gdb backtrace for the conflicting threads.

If WINEDEBUG=mfplat,quartz the extra output that seems related is:

To clarify: these lines happen to early to be direct cause of the freeze, but
look like something related to later set:

wg_allocator.c:312:wg_allocator_release_sample: allocator 0x7fc3fc025f20,

which almost definitely is related to the freeze.
