You can play it with mpv, it depends on the hardware/drivers. It worked fine on a random Ryzen Lenovo laptop with Linux even though MacOS version of mpv couldn't play it correctly on M2 (even though Apple claims that M2 is compatible with the format).

It depends on what format/decoder support went into your particular build of mpv. It offloads almost all of its capabilities onto ffmpeg and its supporting libraries, which in turn won't necessarily be built with exactly everything enabled.
