Except that I don't have ffplay, even though I've got ffmpeg installed:

<snip>I was on 2.8.6 but unmasked and keyworded to get 3.1.3, but still no ffplay.
Is there a special USE flag to enable ffplay to get installed? The previous link lists a whole lot of USE flags, but that looks to be just every flag available for the ffmpeg package and doesn't suggest that I need all of them to get that file:
