For ages, I've been having problems getting my webcam to play with websites that use Flash. The cam works fine with programs like Camorama, but when I try to use it on a Flash site, Flash always crashes regardless of the browser used (Chrome, Firefox, Opera).
I used to use the workaround described here, but since upgrading to 11.04, even that doesn't work any more. I've tried installing the latest flash beta using the Firefox Flash-Aid plugin, to no effect.
When running Firefox in a terminal and try to test my cam on a website like testmycam.com, I get the following error when Flash crashes:
!!! ABORT: X_GetWindowAttributes: BadWindow (invalid Window parameter); 2 requests ago: file /build/buildd/firefox-5.0+build1+nobinonly/build-tree/mozilla/toolkit/xre/nsX11ErrorHandler.cpp, line 199
Using Flash version 10.3.181.36 and Firefox 5.0
