[Techtalk] Open Standard for Video Streaming

[Sujita Purushothaman]

Hi,
  (I'm not really sure whether this question should  go to
issues or techtalk.)
    What are the current standards for video streaming?
Do we have a open standard? What are the apps
available on Linux for this? What are the issues?

Thanks a lot.

Rgds,
Sujita
