Hi Anssi,

A couple of editorial comments (not sure if there's still a window of
opportunity for changes, feel free to disregard if that isn't the case):

- The wording in the abstract seems to imply HTML Media Capture is only
useful to immediately upload captured content. It might be worth
mentioning it gives the document access to the capture content through the
File API which allows client-side manipulation and storing (in IndexedDB).

- I am not sure I fully understand the sentence "These form extensions
enable the upload of still images, video, and audio directly from a device
capture mechanism but capture the default offered by the device, providing
limited control over what is captured."


- It would be great to mention some use cases in there (such as being able
to take a picture using a mobile phone) and what advantages it offers over
getUserMedia (e.g. For pictures, the implementor can implement a hardware
shutter button, offer native image filtering, cropping, save to gallery,
etc., none of which can be done with getUserMedia).

Best,

--tobie
