[gentoo-user] libav/ffmpeg handling via gloabl USE

[Meino.Cramer]

Hi,

this is *NO* complaint/critsim neither implicitely nor explicitely!

I am just curious... ;)

What is the (technical) reason for makeing libav the default instead
of ffmpeg?


Best regards,
Meino

<http://blogs.gentoo.org/scarabeus/2013/01/15/libav-going-to-be-default-provider-for-your-codec-experience/>
has some info about the decision, though I'm not sure it really answers
your question.

It's not really a default as such. That area has been reworked in
portage over the last few weeks and the ebuilds try to figure out what
you want. The USE flags are also confusing, for the longest time
USE=ffmpeg" meant you want av codecs, while USE-libav meant you have
codecs and want to use libav instead of ffmpeg :-)

Two huge threads on -dev since about mid-Jan cover this are, you should
find them on gmane. Subject lines are:

RFC: USE=libav as replacement for broken || ( libav:= ffmpeg:= )
RFCv2: USE=avcodec (+ USE=ffmpeg/libav)
