Hi Soroki,
If live feed isn't important, then DBC will play avi files.
But since live is preferable, the only commands I can think of off the bat would be to use the Multiplayer network commands. I'm just guessing, but with a little bit of clever programming, one could rig up an app that would receive a media stream as if it were a player on a network sending data. The real trick would be in converting the data stream into a human viewable form. For that, you'd probably need a codec in the form of a dll to convert the data stream into video and audio; which could be called through DBC's
call dll command.
Assuming you could get the data streaming, then in theory, instead of a dll, you could send shell commands using DBC's
Execute File to launch an external app like Mplayer(open source) and have it play the streaming data. Using the external app might defeat the purpose though.
To keep the app self contained, using a codec dll and calling it through DBC might be the preferred route.
Enjoy your day.
