Hi all! We just tested WebcamMax and were able to successfully broadcast with it, so please give me some more information to help troubleshoot what's causing the issue on your end:
1. Try downloading the newest version of WebcamMax 126.96.36.199
2. Try using Web Broadcaster in a different browser, such as Chrome or Firefox and definitely make sure your Flash player is up to date by going here: http://get.adobe.com/flashplayer/
3. What filters were you using?
4. How many filters were you using in total?
5. Did you notice it freezing in the WebcamMax screen or just in your Ustream broadcast?
6. At what point did it start to freeze?
7. Did you try refreshing your browser window?
We also tested in Producer and it was working for that as well, so the final step might be to try it in Producer and see if it works for you. To download Producer please go here: https://www.ustream.tv/producer
Thank you all for your patience while we try to pinpoint the issue.
