I don't think that had anything to do with it. I was briefly watching the stream, was next to Joe, and wasn't logged in; the stream window between our screens was the same size. There have been several online video/audio streams from Lilug meetings done by tonyb486 [that's his IRC handle] over time and from that we've found that it's not possible to make a stream that is anywhere near what you would consider a "normal" A/V quality. High-quality video or audio either gets into limits of CPU or outbound bandwidth (especially since each client requires a separate connection), and from experimentation it was found that higher quality audio than video made the stream more tolerable. The stream we had last night was approximately of the same quality that was eventually achieved at Lilug; the only difference was that the Lilug stream used was a long link that can be viewed through a client (Xine, Totem, etc) which allows resizing the video image, where the Mhvlug stream was through a more convenient web page with a static video window size. From my own experimentation, expanding the video from the Lilug stream didn't help get any more detail, but rather only made size of people more into normal perspective -- i.e. being able to resize doesn't matter very much. The bottom line is that I thought the Mhvlug stream from last night worked pretty well and was the best first try I've seen -- the audio seemed pretty clear, the video gave a good impression of what was going on. It may not have been easy or even possible to read some of the presentation text, but I've ever seen a live stream that fully accomplished that. Sean, my congratulations -- that went very well. -- Chris -- Chris Knadle [email protected] _______________________________________________ Mid-Hudson Valley Linux Users Group http://mhvlug.org http://mhvlug.org/cgi-bin/mailman/listinfo/mhvlug Upcoming Meetings (6pm - 8pm) MHVLS Auditorium Jan 6 - Git Feb 3 - Arduino Mar 3 - Gnome 3 & 7 year bday!
