Re: ISSUE-85 (codecs): No provisions for audio/x-speex, video/x-webm, audio/ogg, or video/ogg [Capture API]

Could the additional information be expressed in the codec attribute?

Actually, there's a similar issue with JPEG images.  You can, when creating
a JPEG, specify a "QUALITY" for the encoding.  How does the capture API
allow that to be specified?
