Hi All, On the Xiph Wiki page at: https://wiki.xiph.org/MIME_Types_and_File_Extensions I added Opus to several of the sections, but wasn't sure whether to add "Theora + Opus" to: .ogv - video/ogg .axv - video/annodex As far as I can tell, according to the Opus FAQ at: https://wiki.xiph.org/OpusFAQ#Will_Opus_replace_Vorbis_in_video_files.3F Theora + Opus is

I have been tidying up bits of the Wiki. This one is not clear cut, so I decided to seek advice. Also, I wasn't sure where to post this question, so defaulted to ogg-dev. Should Speex and CMML be removed from the Wiki Sidebar at: https://wiki.xiph.org/MediaWiki:Sidebar ? Many thanks, Martin -- Martin J Leese E-mail: martin.leese stanfordalumni.org Web:

Not sure if this belongs here or in flac-dev. I am subscribed to both, so flop it over if fits better over there. Looking at the Changelog for FLAC 1.2.1 (17-Sep-2007), it says: "With the new --keep-foreign-metadata in flac, non-audio RIFF and AIFF chunks can be stored in FLAC files and recreated when decoding." Where can I find more detail on what is a
