hello,I have a video chat app that needs red5chat installed in root folder-which i dont have access to.Can i run it from a streaming video host,without moving my site? thanks
Yes, you can run. But you have to make sure red5 is installed on a dedicated environment. VPS would do the job anyway as it runs on a dedicated environment.
I think you need create sub domain name or sub folder and use separated database for it (if web hosting account allows it) and go ahead
Here is a tutorial for installing latest Red5 on linux: http://www.videochat-scripts.com/installed-red5-08-rc3-with-jdk-1613-on-linux/
