Bug 71485 – Request: Add amr support into media-video/ffmpeg

• Product: Gentoo Linux
• Status: RESOLVED DUPLICATE

[Description hodak 2004-11-16 20:44:23 UTC]

It is possible add support for amr. To do this one has to specify the following flags when doing configure:
--enable-amr_nb
--enable-amr_nb-fixed
--enable-amr_wb

Then 2 files need to downloaded:
http://www.3gpp.org/ftp/Specs/archive/26_series/26.204/26204-510.zip
http://www.3gpp.org/ftp/Specs/latest/Rel-5/26_series/26073-510.zip

First file should be extracted into libavcodec/amrwb_float, the second one into
libavcodec/amr. 
CFLAGS in libavcodec/amr/makefile shoudl be changed to 
CFLAGS = -Wall -I. $(CFLAGS_$(MODE)) -D$(VAD) -DMMS_IO
 
That should be about it. 
Unfortunatelly, I do not know enough about ebuild to do the changes listed above myself. 

Reproducible: Always
Steps to Reproduce:

amr support is trying to get integrated via the latest cvs snapshot, the duplicate bug listed is currently being tested to make sure that amr works across arches.

*** This bug has been marked as a duplicate of 85407 ***

bug 85407 has been closed; amr support has been dropped from the ffmpeg ebuild.

I would like to request that this bug be reopened so that the possibility of amr
support in ffmpeg can be examined again.

Created attachment 61438 [details, diff]

There are licensing-issues with the amr-support in ffmpeg, thats why they don't
include it, see amr.c:

Nevertheless, I created a small patch based on the attachment in Bug #85407 and
a more current version of the ebuild from the tree, so people can add
amr-support themselves if they want.

The ebuild changed in the last few months [1]
Try and replace the ~alpha and ~ia64 with alpha and ia64 in the IUSE _of the patch_!
