Summer of Code/2009/Multimedia-broadcasting (view source)

Q: '''Describe your project in 10-20 sentences. What are you making? Who are you making it for, and why do they need it? What technologies (programming languages, etc.) will you be using?'''
Q: '''Describe your project in 10-20 sentences. What are you making? Who are you making it for, and why do they need it? What technologies (programming languages, etc.) will you be using?'''
A: This project has two components:
A: This project aims to create an Activity to allow users to easily broadcast and stream audio and video from their webcam and microphone or their computer's display output to a classroom's central server, and share the live feed with their peers. This will be integrated into the Neighborhood View (as a "broadcast audio and video to" option or similar) to allow for most seamless sharing of broadcasts.
Rationale: This project does not aim to recreate Skype or similar central-server small-scale conferencing software. This project's local-peer-discovery and mass-broadcasting architecture would be of use in a classroom setting for the following reasons:
As we have seen in classroom settings such as MIT's TEAL project (for teaching introductory Physics), in the context of displaying live information from a to a large group of students for an experiment, lecture, or the like, a video feed must be established and broadcast, ideally via several video displays. In TEAL, many projectors placed throughout the classroom are used for this purpose; however for an elementary school this would be prohibitively expensive. Assuming said elementary school is running a pilot program of Sugar-equipped laptops, they can instead have each student's laptop "listen" to incoming audio and video broadcasts, and display it when received. This also has the advantage of
Security Architecture
There is an obvious security risk of unsolicited streams appearing on students' laptops, especially if the broadcasting occurs from an online source.
Video Sources
Webcam
X11 desktop output
Icecast will be used for streaming video sources to the laptop.
Video Interaction
There should be some equivalent of a "pointer" on the video, for highlighting important information
Potential Enhancements
These enhancements are probably beyond the scope of a single GSoC project. However, since this architecture has the potential to replace the standard projector-based lecture presentation mechanism, perhaps other, non-video formats, namely PDF lecture slides, might be supported as a future enhancement as well.
Programming Languages: Since sugar-chat-activity uses Python, I will likely be using it for this project as well. The Telepathy and Farsight2 libraries will be used for implementing the multimedia chat feature.
