FFmpeg distribution status

2010-11-02T14:00:53Z

Siretart: link query to packages.ubuntu.com for package status

FFmpeg distribution packages are often incomplete or crippled. Oftentimes they are not crippled, but people claim they are. This page tries to track the status of FFmpeg in distributions to clear up this confusion and provide a quick overview of the situation.

=== Gentoo ===

Gentoo packages are supporting all the available options, including external encoders (like '''x264''' or '''libvpx''').
Given the modular and adapting nature of Gentoo setups, the user defines which features are to be enabled.

The latest stable release as well more recent snapshot are provide across almost every architecture supported.

It is also available a live ebuild in order to track the main branch development.

Check the [http://packages.gentoo.org/package/media-video/ffmpeg Packages] web interface for the up to date status.

=== Ubuntu ===

Ubuntu ships two variants of FFmpeg packages, from which both are uncrippled. The variant in the "multiverse" section has been built against the additional (optional) packages '''x264''', '''mp3lame''' and '''xvidcore''', which enables the respective additional encoders.

FFmpeg is not available on the install DVDs.

Check [http://packages.ubuntu.com/search?suite=default&section=all&arch=any&searchon=sourcenames&keywords=ffmpeg packages.ubuntu.com] for the up to date status.

=== Debian ===

The packages in Debian '''Squeeze''' are uncrippled. Packages in Debian '''Lenny''' packages are based on a snapshot from '''February 2008''' and have the following some encoders disabled:

* h263
* mpeg2video
* mpeg4
* msmpeg4 (and variants)

Note that even Debian Squeeze does not ship the packages '''x264''', '''xvidcore''' or '''mp3lame''', which means that these packages cannot be used for encoding to [[h264]] or [[MP3]].

=== Fedora / Red Hat (unverified) ===

Fedora does not have any sort of multimedia in their repositories, except for the Xiph kind. FFmpeg and other packages are available from the livna repositories.

=== OpenSUSE (unverified) ===

The status regarding OpenSUSE is unknown. Supposedly they ship no FFmpeg packages, users need to get them from packman instead.

FFmpeg Release Plan

2010-03-02T13:36:58Z

Siretart: we will use the FOSDEM motto for 0.6

Ideas and suggestions concerning FFmpeg software releases.

==Things that need doing==
* Fix SVQ3 regression test?
* Approximately 95% test coverage in FATE.
* AAC Conformance sweep
* Make sure API/ABI changelog is up-to-date

=== Release 0.6 "Works with HTML5" ===

Pending features that would be nice to have in 0.6

* HE AAC v1
* LATM demuxing support

==Release Criteria==
* make test passes.
* FATE test coverage passes for all platforms of interest.
* All 'important' bugs reported in roundup fixed/closed.
:Except 46, 127 and possibly 192 and 452 --[[User:Ce|Ce]] 05:36, 3 February 2010 (EST)
:And NetBSD status? https://roundup.ffmpeg.org/roundup/ffmpeg/issue886
* No half-implemented functionality that may break existing user apps.
* Endurance/memleak testing on film-length files.

==Rationale for releases==
* Provide endorsed snapshots for external software developers to develop against
* Avoid sitation where external software developers using SVN head when head has transient limitations.
* Discourage external software developers using ancient snapshots that we don't support.

==Release Process==
* Create a branch in Subversion.
* Replace version.sh by something that hardcodes 0.6.
* svn export svn://svn.ffmpeg.org/ffmpeg/tags/0.6/ ffmpeg-0.6
* tar -cvjf ffmpeg-0.6.tar.bz2 ffmpeg-0.6
* Get source code
* Create tarball
* Checksums?
* Upload to ffmpeg.org
* Update website
* Who needs to be notified?
** Major dependent projects, major distribution package maintainers --[[User:Rathann|Rathann]] 09:43, 29 January 2009 (EST)
