It's documented frequently on this mailing list. I don't know if it is documented in a more permanent place like the wiki or guide. > The place where these instructions would have done me good is in the > Migration instructions: <https://trac.macports.org/wiki/Migration>. The migration instructions are intended to help you move an existing MacPorts installation to a new system, preserving it the way it was installed as much as possible, so any advice about what variants you should choose seems like it would be misplaced in that document. > I just looked.

Thank you for the heads-up. The x11/quartz distinction is primarily significant for gtk2/gtk3 since those ports can currently only be built for one or the other, and which flavor of gtk you use dictates which flavor of all the ports that depends on gtk you can use. Chris wishes to begin work on making these available as subports instead of variants so that they could coexist and this limitation would then disappear. ffmpeg's x11 variant does not have anything to do with gtk, so you can make that decision separately from the ports that do use gtk. ffmpeg does use libsdl2 and, if you use ffmpeg's x11 variant, it requires that you use libsdl2's x11 variant as well. It will let you know about that if you haven't already done that.
