Dear Thierry,

Thank you for your message below.

I don't agree with the statement that speex or VP8 are not metadata
formats.  They are audio and audiovisual media formats which contain
both metadata and data in their specifications.

This disagreement can be resolved if speex and VP8 are included in the
media ontology.  Four weeks ago I asked the Device API working group
if there were any objections to the use of speex as a default audio
format, and there were no objections which proposed a superior format
or contained any reasons why speex was not a suitable default audio
format.  There have been about five objections stating that consensus
may be unlikely, all of which were based on historical difficulties in
achieving consensus for codec defaults which occurred during pertinent
conditions which I do not believe are true today.

Best regards,
James Salsman
