Bugzilla Bug 76212

if libmp4v2 is installed by faad2 and then faac is installed.. the resulting
library will depend upond libmp4v2.... but that's not in the ebuild... There
should probably be some configure patching/seding to make that controlable
through use flags... 
And while I'm at it.. faac refuses to build if mpeg4ip is installed, but
mpeg4ip depends on faac...

Patch to add dependancy on faad2 if mp4 USE flag is set

I made some small changes to the RDEPENDS and built it on an x86 machine.  Faac
now reports to have mp4 support.

this is not enough... you have to have the configure script too to disable
faad2 if the mp4 flag is not set...

That seems good to me.. Except that the mp4 depend should be "|| (faad2
mpeg4ip)" I think... it would need to be tested

I feel it's worth duplicating my comment here. I ran into a compile error (bug
111426) when trying to compile faac:

The reason I was trying to install faac was because it was being pulled in as a
dependency of media-video/mpeg4ip-1.2

I gave up on that version and went to mpeg4ip-1.3 which doesn't depend on faac.
I noticed that mpeg4ip-1.3 provides mp4.h so it looks like the dependencies
might be the wrong way around here..?


So, faac depending on mpeg4ip maybe isn't such a good idea (circular
dependencies, anyone?)

Both faad2 and mpeg4ip provide libmp4v2 (and mp4.h). The version in mpeg4ip is
newer.. but faad2 is a much more common package (and smaller). If you already
have mpeg4ip and build faad2, faad2 will use the mp4v2 from mpeg4ip (but it wont
work the other way around).. and it creates an unwritten dep.

The right solution is to separate libmp4v2 into its own package that both would
depend on.. but I have not been able to convince upstream mpeg4ip to do that.
And upstream faad2 was pretty much dead the last time I checked.

Reporting here since it seems relevant in the discussion that has already
started...

I've just encountered the following issue trying to compile mpeg4ip-1.3:
* libfaac is compiled against libmp4v2
* Please remove faad2 and mpeg4ip then recompile faac

My workaround was to add a configure option to faac which allow to
enable/disable linking against libmp4v2 (instead of having it auto-enabled when
the lib is installed). It seems similar to Scott's proposal, although i think
it's a bit cleaner since it is against configure.in, so i will attach it in
case
it's useful. Note that i'm not sure i've really understood the issue discussed
here though, i've just tried to make things compile for me, nothing more...

faac-configure-mp4-support.patch

The configure.in patch for faac-1.24.

Created an attachment (id=72148) [edit]
faac-1.24-aac-USE-flag.patch

Patch for faac-1.24.ebuild: enable/disable linking against libmp4v2 depending
on the "aac" USE flag (although i'm not sure it's the right USE flag...)

the problem is with ffmpeg too... 
 
there should be a sort of "virtual/aac" 

as suggested in  
 
http://bugs.gentoo.org/show_bug.cgi?id=58288 
 
a good thing should be making faad2 depending on mpeg4ip, so all problems go away 

someone hurry up and fix this it is becoming annoying. I'm going to have to
lose
mpeg4ip otherwise since more apps seem to use faad2 for aac instead.

Should be fixed with 2.0-r8.

*** Bug 140336 has been marked as a duplicate of this bug. ***

Ok, so since this bug is RESOLVED AND my bug (#140336) has been marked as a
duplicate of this bug:

What is the solution for us running stable x86?

I can't emerge faac when faad2 is installed, if I delete faad2 and emerge
mpeg4ip then faac compiles, but I'll still get:

[blocks B     ] media-video/mpeg4ip (is blocking media-libs/faad2-2.0-r3)
[blocks B     ] <media-libs/faad2-2.0-r9 (is blocking

Having read the discussion, I have no idea how to get my system to work.j
