This page is for collecting patches related to the MIME type and file extension changes outlined in MIME_Types_and_File_Extensions.
Please add links and information about your favorite applications to this page!
Standards
RFC 5334 has registered video/ogg and audio/ogg, and redefined application/ogg.
Please read the IANA Application for Media Type for details of the registration procedure.
Recommendations
Players, File managers etc.
Applications which read (decode) Ogg files should be extended to additionally recognize the file extensions .ogv, .oga, .ogx as outlined in MIME_Types_and_File_Extensions.
.ogg and .spx are kept for backwards compatibility for Vorbis and Speex respectively. Nevertheless, .oga should be considered an alternative extension by all programs.
Programs that deal with media types, should recognize video/ogg, audio/ogg, and application/ogg. They should also be able to either recognize Skeleton, or at least be able to play files with a Skeleton stream without problems.
Encoders
Applications which create Ogg Theora files should be modified to default to the extension .ogv rather than .ogg.
Applications which create Ogg Vorbis or Ogg Speex files should be modified to allow use of the extension .oga, but should continue to default to the extensions .ogg and .spx respectively. Ogg FLAC applications must be modified to support the .oga extension only.
Applications
Players
GStreamer
A GStreamer hacker writes: gstreamer more or less doesn't need anything. There's one tiny thing that could be changed, but it's in API that nothing currently uses, so it doesn't matter.
MPlayer
Mplayer successfuly plays .oga files such as those at XMLEmbedding. The mplayer Firefox plugin on Linux loads to play audio/ogg.
VLC
mime type associations have to be updated so VLC knows that it supports new extensions VLC ticket
xine
- xine ignores file extensions on loading, so it can already play files with the new extension .ogv.
- xine implements a generic demuxer, so it can already play Ogg Audio (.oga) files containing additional bitstreams, ie. its Ogg Audio support is not limited to Ogg Vorbis I (Vorbis-only) files.
- xine support for Ogg Skeleton bitstreams.
Nevertheless, this PATCH adds metadata for the new filename extensions and MIME types to xine's Ogg demuxer, which is useful in reporting xine-lib's capabilities.
Songbird
Amarok
Amarok developer reports: We get the list of supported filetypes from the engine, and the engine gets it from the backend (e.g. xinelib). Amarok itself doesn't distinguish between formats at all.
XiphQT
Arek released a new version, stating it does support the new MIME types and file extensions.
FFMpeg
FFMpeg is not able to play ogv files with Skeleton stream since it treated as a video stream with a higher importance than the Theora stream.
- I have not seen this problem during my own tests. Going back to test ffmpeg.--Ivo
File managers, servers etc.
Apache
Ticket filed in. Waiting for approval.
Konqueror
Nautilus
Nautilus (and the whole of GNOME) uses the f.d.o shared-mime-info package. Patch: https://bugs.freedesktop.org/show_bug.cgi?id=12890 (please check)
Encoders
ffmpeg2theora
Version 0.21 uses .ogv and Skeleton by default.
VLC
VLC also encodes to Ogg container. Ticket is open regarding the use of Skeleton. They welcome a patch.
