Since didn't find entries about the issue searching around, will add this note to help others tryng to do the same. The idea is this:
- two live videos (one big, the other small) switching position, that means the low video quality goes to the big slot, the high video quality goes to the small slot
- The low video quality looks bad in the big slot, so should change NetStream video quality on the fly
- When switching again browser crash
After alot of testing, find that the problem is related to the Video object swtiching from a Webcam to a NetStream and the Webcam again. When returning to the webcam, the browser crash (Firefox 3 and IE 7 on Windows Vista, Flash Player 10) SO I was forced to change the video object (remove from the displayList, create a new one and add again) before reattaching the webcam again.
This is important, because my first guess was that the problem resides in dinamically change NetStream quality (manipulate the webcam settings) ... but the problem was not there.
Hope this is just a problem of this versions of browser/flash plugin ... anyway ... just for the records
