ppa-purge failed (didn't want to replace running kernel and it couldn't find aptitude), leaving the system unstable. Did a clean reinstall of 21.04 from ISO to get a usable system (obviously without PPAs), restored home dir from nightly backup. Back in business ... mpv can now do mp4 files without error and vainfo also works without error. So you were right. But I think ppa-purge needs work. Thanks.
