FFmpeg maintainers ================== Below is a list of the people maintaining different parts of the FFmpeg code. Please try to keep entries where you are the maintainer up to date! *Status*, one of the following: [X] Old code. Something tagged obsolete generally means it has been replaced by a better system and you should be using that. [0] No current maintainer [but maybe you could take the role as you write your new code]. [1] It has a maintainer but they don't have time to do much other than throw the odd patch in. [2] Someone actually looks after it. A (CC
) after the name means that the maintainer prefers to be CC-ed on patches and related discussions. (L
) *Mailing list* that is relevant to this area (W
) *Web-page* with status/info (B
) URI for where to file *bugs*. A web-page with detailed bug filing info, a direct bug tracker link, or a mailto: URI. (P
) *Subsystem Profile* document for more details submitting patches to the given subsystem. This is either an in-tree file, or a URI. See Documentation/maintainer/maintainer-entry-profile.rst for details. (T
) *SCM* tree type and location. Type is one of: git, hg, quilt, stgit, topgit Applications ============ ffmpeg: ffmpeg.c Michael Niedermayer, Anton Khirnov ffplay: ffplay.c [2] Marton Balint ffprobe: ffprobe.c [2] Stefano Sabatini Commandline utility code: cmdutils.c, cmdutils.h Michael Niedermayer QuickTime faststart: tools/qt-faststart.c Baptiste Coudurier Miscellaneous Areas =================== documentation Stefano Sabatini, Mike Melanson, Timothy Gu, Gyan Doshi project server day to day operations (L: root@ffmpeg.org) Árpád Gereöffy, Michael Niedermayer, Reimar Doeffinger, Alexander Strasser, Nikolay Aleksandrov, Timo Rothenpieler project server emergencies (L: root@ffmpeg.org) Árpád Gereöffy, Reimar Doeffinger, Alexander Strasser, Nikolay Aleksandrov, Timo Rothenpieler presets [0] metadata subsystem Aurelien Jacobs release management Michael Niedermayer API tests [0] Communication ============= website (T: https://git.ffmpeg.org/ffmpeg-web) Deby Barbara Lepage fate.ffmpeg.org (L: fate-admin@ffmpeg.org) (W: https://fate.ffmpeg.org) (P: https://ffmpeg.org/fate.html) (S: https://git.ffmpeg.org/fateserver) Timo Rothenpieler Trac bug tracker (W: https://trac.ffmpeg.org) Alexander Strasser, Michael Niedermayer, Carl Eugen Hoyos Patchwork [2] (W: https://patchwork.ffmpeg.org) Andriy Gelman mailing lists (W: https://ffmpeg.org/contact.html#MailingLists) Baptiste Coudurier Twitter Reynaldo H.
