That is effectively strange. There is a little hint of what could possible be
wrong on your OS. The tip of the backtrace is in iHD_drv_video.so, this is the
software part of the Intel VA driver (video decoder accelerator). I haven't seen
such a crash recently, but perhaps pops have a packaging bugs (e.g. drivers and
gstreamer-vaapi not being built against the same version, or other issues like
this).

I think to get doing, the simpliest thing is just to uninstall gstreamer-vaapi
package (not sur of it's axact ubuntu name, but I'm sure you'll find with with
apt search vaapi). This will fallback to FFMPEG software decoding and will
likely "fix" the issue. It's not relevant to your learning after all.
