I've added the following useflags to base/use.mask and media-video/ffmpeg uses them. Please unmask the useflag on the mips profiles where they are supposed to work. mips32r2 mipsdspr1 mipsdspr2 mipsfpu
to be honest, all these flags can be used by all profiles. It really depends on what CFLAGS the user uses in his make.conf and what hardware he has. I suggest to unmask all of them and let the users pick those that work on their hardware.
I unmasked all of them in arch/mips/use.mask + 23 Jan 2014; Markos Chandras <hwoarang@gentoo.org> use.mask: + Unmask ffmpeg MIPS use flags per #498082 +
