It looks like we'll need to serve streaming Dvideo out of Zope in some generally playable format (IE, Mozilla, Opera, etc.) on a variety of platforms (Wintel, MACS (MacOS 8.6, 9, 10), Linux, etc.). The format's somewhat open, but since bandwidth is a consideration and the video streams are significant (an hour to 90 minutes), MPEG is probably not a first choice. It's been suggested that the right control language might be SMIL. Anyone have experience in this arena they'd be willing to share. What works? What are the hidden gotchas?
Here (University of Nice) we use RealServer which serves both video files and SMIL files, while the best would probably be to create SMIL files on-the-fly with Zope. Zope is actually only used for "presentation" only wrt audio/video sessions, and generates a page with links to the audio/video stream and an associated IRC channel for instant feedback during live sessions. We plan to use Zope to control audio/video sources (RS232 grids) and also move (pan/tilt) cameras via an AXIS 2400 video server, but I'm still waiting for this to be delivered... bye, Jerome Alet
