Contents

.ogg - application/ogg

  • can contain any logical bitstreams multiplexed together in an ogg container
  • has been defined as such in RFC 3534 http://www.ietf.org/rfc/rfc3534.txt
  • .ogg has traditionally been used for Ogg Vorbis files, so an important subpart of the ".ogg" files will be just Ogg Vorbis
  • .ogg has more recently also been used for Ogg Flac and for Ogg Theora/Vorbis
  • it is required that random multitrack files contain a skeleton track to identify all containing logical bitstreams


.oga - audio/ogg

  • audio in ogg, e.g. vorbis, speex, flac, ghost

.ogv - video/ogg

  • a/v in ogg, e.g. Theora, Theora + Vorbis, Theora + Speex, Theora + flac

.spx - audio/ogg+speex

  • .spx has traditionally been used for Ogg Speex files


Codec MIME types

Codecs need their own MIME types for streaming and to be used in multitrack ogg files using skeleton:

  • audio/vorbis for vorbis w/o container
  • video/theora for theora w/o container
  • audio/speex for speex w/o container
  • audio/flac for flac (is audio/flac currently being used for flac in native container?)
