Description of problem:
Hi!

The crashed happened when trying to play a movie.
.mkv container
H265 codec
Dolby DIgital 5.1 Atmos w/ Dolby Vision (DoVI)

was 4K (3840*2160) resolution, with HDR10.

Upon playing the file totem basically turned into a "memory bomb" and quickly used gigabytes of memory, before exhausting RAM and swap and the oom killer terminated the process
(the out of memory process killing thing you guys added works great by the way!)

Thanks!
