782139 - Delete temp picture files once the page is closed generated from mozGetUserMedia

Status: RESOLVED WONTFIX

(Core :: WebRTC: Audio/Video, defect)

Description

[Jason Smith [:jsmith]]

Steps:

1. Call mozGetUserMedia with {picture: true} with a valid success/error callback
2. Inspect the stream object returned

Expected:

The object returned should provide no indication that something was written to the local filesystem without the user knowing. The picture should represent an in-memory reference.

Actual:

A JPEG image file is written on Windows to C:\Users\<user>\AppData\Local\Temp. This seems incorrect - we shouldn't be polluting the user's temp folder with images generated by a picture taken - I would think this should be an in-memory reference. Not only that, but we shouldn't assume that the temp folder is always wiped immediately after a short period of time (days, hours) - Checking my folder right now, I still have pictures generated from the API as old as 7/13/2012. As a result, I've got around 90 pictures in that folder right now sitting around collecting harddrive space. We should do something better here.
