this works for taking stills. Probably need some design love though

If I were writing the JS parts i would use a more Object based approach instead of the global funcs and data style used here (and probably prevalent in the older file picker code) I assume this won't work from e10s since the component will try to load in the child process. Overall approach looks good to proceed.

:imelven - does this need reassignment since sec realignment?

(In reply to Curtis Koenig [:curtisk] from comment #2) > :imelven - does this need reassignment since sec realignment? yes, but it looks like this bug isn't currently active ?

I think this may have ended up being the getUserMedia work instead ? sending to mgoodwin as it's mobile but don't think there's anything to do here..

I've spoken to blassey about this; he says: "I think getUserMedia's impl has made that irrelevant".

See comment 5

getUserMedia and HTML media capture have a very different set of use cases, and implementing one doesn't obsolete the other. As of now, getUserMedia doesn't have the necessary APIs to take high quality pictures, it also forces the developer to build his own API for taking pictures instead of being able to rely on the device's camera application when there is one (frequent on mobile devices). Please reconsider closing this.

Ah, apologies; I though this was the secreview bug. Un-closing

The secreview bug!?

(In reply to Tobie Langel from comment #9) > The secreview bug!? Yeah; the security review for this feature (there doesn't seem to be a separate bug for this). Security reviews for bugs that seem dormant aren't necessarily the best use of time, which is why I was closing it out.

Isn't this bug related to the old and ugly capture button that was in Fennec XUL? I doubt this is needed for bug 741393. Bug 741393 could simply make the intent fired when the <input type='file'> is activated different and only use the capture handlers. IMO, we should close this bug and work on bug 741393 instead.

This is now implemented via getUserMedia
