RealMedia files will stream just fine from Coppermine without special server licenses or configuration. Having a streaming server helps smooth things out, but most modem connections are fast enough these days that if the compressed video file is optimized for 56K modems, they will stream just fine using HTTP.
Instead of uploading the video .rm file through Coppermine, put the .rm file online somewhere on your server. Then create a text file that contains nothing but the full (absolute) URL of the .rm file, and name it with a .ram file extension. Upload the .ram file via Coppermine. That's all you need to do. The only problem is that an unnecessary new window will open. I haven't taken the time yet, but I'm sure there's a place to put an if statement that will suppress opening a new window when the filetype is .ram.
Does anyone know where that would be offhand?
I suspect you could also stream other media by creating an HTML file with the requisite embed tags, and uploading the HTML file instead of the video file through Coppermine. The video file itself can be uploaded using FTP software.
Hope this helps!
