Please keep mplayer mail on the list!! We have a list for a reason!
OK, so I see what the problem is. Maybe if we just wait a few weeks,
the whole detection nonsense will be a non-issue? Unisys patent
expires very soon now so hopefully people will stop using this stupid
If you do want to fix it now, I suppose you're right -- force-yes is
not a valid option for gif right now... :/
