Finally, popular P2P streaming player Sopcast is available for OS X. Some may prefer using an external video player like MplayerX or VLC instead of the embedded mplayer; here's how you can do that.
The Sopcast OS X application is basically a package of the streaming server (sp-sc-auth) and a video player (mplayer) together with a simple GUI. The mplayer part is a very basic instance without keyboard shortcuts, so some functions like setting aspect ratio are missing. One may prefer to use the full MPlayerX application or VLC as the video player. Using Terminal it's possible, the only drawback is the missing convenience of clicking on sopcast: links in browsers. The link should be copied into a terminal command:
$ /Applications/SopCast.app/Contents/Resources/binaries/m32/sp-sc-auth sop://broker.sopcast.com:3912/xxxxx 3908 8902 > /dev/null
http://localhost:8902Sometimes for some reason the video players can't pick up the video stream, they need to be restarted. To stop the streaming server, press Ctrl-C in Terminal.
