User Agent: Mozilla/5.0 (Windows NT 5.1; rv:16.0) Gecko/16.0 Firefox/16.0
Build ID: 20120722042009

Steps to reproduce:

Visited the site http://sochicamera.ru/#cams1 containing the OnLine video streams from several camcorders in Sochi city.


Actual results:

Attempting to switch between cameras causes the changing of only the frame, the stream itself continues to transmit the initial (first runned) one. Can be stopped only by the page reload.


Expected results:

Switching between cameras should cause the interruption of previous stream and starting of transmissin of corresponding stream.

It's weird because the webcam site works now (with FF14+). But that wasn't the case when I used mozreg to find the regression range 3 weeks ago, the current Flash plugin instance of a webcam played the video stream of the previous webcam loaded.

I used mozreg again and I found a new regression range, where the Flash video stream doesn't load.

m-c
bad=2012-03-31 (no video stream)
good=2012-03-30 (video stream played)
http://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=92fe907ddac8&tochange=4c43cfe73516

So I guess it's fixed by bug 737433 that's a regression of bug 90268.

But why is it fixed "magically"? Has the webcam site changed its code?

I'm not able to reproduce the issue with Firefox 19, confirming my previous comment in August 2012. Closed for now.
