Details

Description:

Of the supported video codecs, only Theora and VP8 appear to be available. This means that (at least) H263, H263-1998 and MPEG4 are missing.

Additional info:
linphone 3.5.2-4
ffmpeg 1:0.11.1-1

Tested on both i686 and x86_64.

Steps to reproduce:

Install linphone. Open it, go to Options->Preferences, then the 'Codecs' tab. Change the dropdown box to 'Video Codecs'. Only VP8 and theora appear.
This task depends upon

Does mediastreamer-plugin-msx264-git and linphone-plugin-msx264 packages from aur help?
Comment by Sergej Pupykin (sergej) - Monday, 17 September 2012, 09:56 GMT
linphone-plugin-msx264 gives h264 support. I don't know why other codecs are missing, while linphone depends on libavcodec...

Btw, it is more likely mediastreamer related issue

I have investigated this, and have a sort-of fix. It is indeed a mediastreamer issue (and should be changed from "community packages" to extra).

Because mediastreamer depends on an old version of avcodec instead of a recent version of ffmpeg, there are compatability issues. The current solution[1] in Arch was to patch mediastreamer to #ifdef out the problem code... which disabled most of the codecs.

I have attempted to modify the patch (attached) to add actual compatability for Arch's version of ffmpeg. The codecs do appear, but MP4V-ES is the only codec that works (of the ones that were missing).

About linphone-plugin-msx264: yes, it gives h264, but h263 should be built-in.

Move to extra and assign to current maintainer?

Greg: sounds good.

This has been fixed in upstream git (in June of last year), attached is the relevent git patch. It applies to the release tarball (with a little fuzz), and makes everything work. Just download the patch, and update md5sums.
