The sample provided in the post above is not triggering the crash.
However a sample was provided to me that reliably crashes.
https://drive.google.com/open?id=1bDhF6U5ccW-K1G63fl1qnO-98kopMJyw
ryzen 2400g
linux 5.1.10
mesa 19.1.0
ffmpeg 4.0.3
libva 2.5.0.pre1 (from git)
kodi 19 (from git)

I have a stacktrace but it's quite useless, if needed I could rebuild all the
packages with debug info and reproduce.
I don't have another player on the affected system atm.
