Another useflag-related question.

Currently, the encode useflag is defined as follow:

encode - Adds support for MEncoder or LaME encoder, wherever applicable

this is a loose definition which is quite useless for medium user, as it's 
used also in a non-complete-standard way in all ebuilds.

My proposal is to start using lame useflag to enable lame support (in software 
which is just encoding on itself), and using encode with a slight different 
definition for example:

encode - Adds support for encoding files in addiction to decoding

so that it can be used to enable generic encoding support instead of specific 
using lame or mencoder.

Comments?

why not re-use the 'mp3' USE flag ?

how many packages actually make 'encoding' an optional feature ?

I don't like it. I'm in the group of people that think there are already
way too many use flags. I think a better solution is for someone to go
ahead and work on getting use flag description info added to the
metadata.xml files. It is after all supposed to be extensible isn't it.

because LAME Ain't an  Mp3 Encoder? ;)

I guess the focus here wouldn't be on supporting mp3-encoding as such
but using lame over another lib to do the same job.

'the same job' ?  you mean making mp3s ?

lame doesnt produce any other formats than mp3s afaik

But there are other libraries which produce mp3s. Lame is just one of them.

whats your point ?

if you created a USE=lame, it would simply be a subset of USE=mp3

But USE=mp3 could mean mp3 decoding support in audio players, while
lame is not a decoder.

so ?  can you show me a package that this difference matters ?  if not, then 
having lame sep from mp3 is pointless ...

It's analog to the lesstif use flag:

lesstif - Use lesstif over openmotif in cases where a program supports both

lame - Use lame over $OTHER_MP3ENCODING_LIBRARY where both are supported

At least that's what I think is flameeyes' idea.

Is there a package where this could apply?

We have couple of packages which can use both lame or toolame.

...toolame doesn't seem to do mp3s, so it doesn't overlap with lame.
(and btw it seems a dead project since two years, who would want it ;)

looks like there is yet another fork called twolame[1] that is mantained.
