Yet, you have Audio and Video in Sysinfo [1,2]. Which shows that there 
is necessarily an arbitrary separation needed: you don't want zoom 
control in System-info, and you don't want loudspeaker/headphone 
information in Capture.

One way is to have:
- hardware and software capabilities (all read-only): system-info. 
Includes codecs, connectected speakers, microphones, etc.

- capture: select which camera to use, select zoom level, capture()

- playback: covered by HTML.

Still, having to use SysInfo to query the cameras connected and Capture 
to select which to use isn't great. And where do you put functions to 
select which loud-speaker to use?
