Here are my comments from ACTION-191:

AudioCodecAttributes contains "compFormat" --
http://dev.w3.org/2009/dap/system-info/#widl-AudioCodecAttributes-compFormat
 -- while the VideoCodecAttributes contains "compFormats". Those
should both be plural as "attribute DOMString[] compFormats;" and they
should be space-separated lists of MIME types, not free form.

The declaration above
http://dev.w3.org/2009/dap/system-info/#widl-VideoCodecAttributes-hwAccel
should also be pluralized with "attribute boolean[] hwAccel;" instead
of omitting the "[]".

Under http://dev.w3.org/2009/dap/system-info/#idl-def-MicrophoneAttributes
there needs to be a "name" attribute with values such as "microphone",
"camcorder", "webcam", or "line-in" (suitable for use as a
;source=name type parameter in input elements for forms, e.g., input
type=file accept="audio/x-speex;quality=7;bitrate=16000;source=webcam")
and a "types" attribute (not to be confused with the existing "type"
enumerated attribute) as a space-separated list of available MIME
types such as "audio/x-speex audio/ogg" to go along with the frequency
ranges already in the draft.

Similarly, http://dev.w3.org/2009/dap/system-info/#idl-def-CameraAttributes
needs to include attributes "name" and "types" such as "camera" and
"image/png video/x-webm ..." respectively.

Finally, regarding the Media Capture API, per ISSUE-85 it is not
appropriate for
http://dev.w3.org/2009/dap/camera/#widl-FormatData-type to refer to
"audio/x-wav" which is a union type with multiple serious drawbacks.
Please replace it with "audio/x-speex or audio/ogg" which are
unencumbered types of appropriate quality.
