Are we talking about different things?  On my Android phone, the
Google Goggles app takes still photographs, not videos.

There's no problem in making both available, as long as it doesn't
distract or confuse the user.  At a minimum, authors will in some
cases legitimately want to tell the UA which input mechanism to
emphasize, for UI quality reasons.  Good UI will direct the user
toward the most likely action and will not offer alternatives (at
least not prominently) that the user is very unlikely to want.

apps, it is.

It's somewhat uncommon to offer a generic dialog that gives the user the choice of existing file or capture. For example, on Mac OS X, Preview opens files and doesn't do camera capture. Photo Booth can take pictures with the camera, and doesn't even have an option to choose an existing file (even though you could imagine that applying its photo effects to an existing file might be useful). On iOS, you see the same pattern. Apps generally offer access to the system photo collection or their own image collection separately from camera capture, even if they provide both. And many apps only do one or the other.

I agree with this, although I'll add that it would be good if web apps
automatically gave the user the *option* to use files from a different
source than the author expects (unlike the OS APIs we're discussing,
which require extra author work to get that effect).  But the author
still needs a lot of control over how that option is presented, to
create a good user experience.
