Can I play x265 1080p 24fps video smoothly on the RPi3?

Thanks. There doesn’t seem to be any much feedback on x265 playback beyond this thread, where one person has reported smooth playback, while the other person hasn’t. I guess I will have to try it for myself.

Also, is it enough if I power the RPi3 by connecting it to my TV’s USB port when playing x265, or will I need some kind of external power supply? Sorry if this is a noob question.
