system memory size: 31GiB, 2 15.5 GiB cards

cpu: Intel® Core™ i7-7500U CPU @ 2.70GHz, version: 6.142.9, size: 3268MHz, capacity: 3500MHz, width: 64 bits

no graphics card whatsoever

computer can play h.265 and equivalent without troubles, provided video file is no higher than 1080 p.

Computer can play av1 files no higher than 1080 p only if I shut every other application down. If for example I run a browser and an av1 file with either mpv or vlc, system shuts down.

Can I put all that memory to use and avoid overloading the cpu?

    For HEVC and AVC playback, your built-in GPU is used. Kaby lake doesn’t support AV1 hardware decoding so it’s hitting your CPU directly.

    The shutdown could be a number of problems

    1. Do you have high memory usage while playing AV1 videos?
    2. Does the video start playing and then crash your system or is it an immediate crash?
    3. Do you have swap space assigned and how much? Check with free -h
    4. Are you having thermal issues? Do the fans kick in like crazy before shutdown or can you see very high temperatures with sensors?
