Dear Maintainer,
tried to reproduce the steps and found neovim crashing too.
Used a minimal testing VM, created a test video with ffmpeg.
This led to the backtrace below.
In the meantime someone created this upstream bug describing a
similar situation and showing the same backtrace:
https://github.com/neovim/neovim/issues/12366
Kind regards,
Bernhard
