Here are three more projects which provide P2P video support for Linux:
SwarmPlayer
Veetle
Tribler
Both SwarmPlayer and Tribler are tstream capable. Tstream is a new torrent format specially designed for video.
You can find tstream files on eztv.it
Enjoy!
The following is from the Sopcast installation page on Google Code
When you make sure that Sopcast is functional, close it. Here’s what I did to open sop:// protocol links automatically in Firefox:
1. In Firefox, in the Location bar, type about:config and press Enter.
2. Right-click anywhere in the grid, choose New, then String.
3. In the Enter the preference name prompt, type in network.protocol-handler.app.sop and press OK.
4. In the Enter string value prompt, type sopcast-player and press OK.
5. Try to open sop:// link on your favorite website and you will be presented with dialog box where you can search location of sopcast player. Navigate to ~/usr/bin and point to sopcast-player and click OK.
6. OK out of dialog box and now all sop:// links should open sopcast player automatically.
Please note that parts 5 and 6 were written from memory so some of the wording might be incorrect but it should be pretty intuitive.
Hope this helps, Iakov.
