786081 - Cannot stop a video already started from getUserMedia

Status: RESOLVED DUPLICATE of bug 784829

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

Description

[Jason Smith [:jsmith]]

Steps:

1. Go to https://people.mozilla.com/~anarayanan/gum_test.html
2. Select video
3. Select stop

Expected:

The camera stream should stop running (no light on the user's webcam).

Actual:

The camera stream does not stop. As a result, if I try to start video, picture, or audio again, I'll fail out with an error saying HARDWARE_UNAVAILABLE for picture and video, NO_DEVICES_FOUND for audio.

This is an obvious blocker, so I'm automatically going to triage this.

Comment 2

[Jason Smith [:jsmith]]

Also, ignore the issue I hit with audio in comment 0. That's the same old issue that you can't use audio twice with gUM.

Roc - Do you have any ideas what might have caused this regression?

I know bug 785001 landed recently to fix the crash, but would that cause this regression? I see other bugs such as the ones below in the changelog as well:

* bug 785671
* bug 767480

Maybe bug 779715.

I can confirm using this program:

http://alexandre.alapetite.fr/doc-alex/html5-webcam/index2.en.html

That I cannot stop the video once I start it. I'm using OS X 10.8.1 and the latest nightly 08/29/12.

I can also confirm that Chrome works properly using the same link.

Fixed by the patch in bug 784829.
