I was under the impression that 8 was the limit. Thus the extra white space JM adds on Speex and CELT magics. I may be wrong, though. > So it's 7 for Vorbis and Theora, 5 for FLAC So

...here's the > recent string. It's supposed to be finalized though there many be some granulepos issues still in current implementations. I don't expect the BBCD\0 magic to change. OggMNG defines the following magics: char[8]: "\211PNG\r\n\032\n" png char[8]: "\212MNG\r\n\032\n" mng char[8]: "\213JNG\r\n\032\n" jng Are the 'Codecs Parameter' values from a different namespace from the media-types? Do we define a mapping where there is one, e.g. vorbis is audio/vorbis? And there's OggY4M which uses char[9]: "YUV4MPEG2" bu...
