I gave it a quick test with a sample the other day, and it seemed to play fine on a non-overclocked PI3, albeit all 4 cores seemed to be maxed out. I tried an older test encode from over a year ago that I remember I had done using "fastdecode" flag, and CPU usage was down at like 30%. So I assume it's still a thing, but I'm not sure if it was just related to the test-sample I did without fastdecode and that a different movie/sample might perform better.I think you'll be fine with any sane options. Might be worth running bcmstat.sh when playing the file.
If 4 cores are maxed I suspect we haven't even triggered turbo mode and the arm cores are running at 600MHz.
