Made a fair amount of progress today.
I solved a fairly serious problem where Zaza would occasionally crash into obstacles after visitors 'herded' her into them. It ends up we weren't using a critical component of the high-level collision avoidance code, and hadn't noticed until now. Oops ;)
I fixed a bug in the voiceClient Perl code that caused the Java face applet to get 'shy' and stop talking when it received a bad speech request from a client.
Last week I submitted a few pages I have been working on for the Tech's website about Zaza. Hopefully the Tech's webfolks will have it up in a week or so.
The FFmpeg team is nearly ready to release another official version that will fix some of the problems with live streaming. It's been nearly nine months since the last release, so it's been a long time in coming. This will allow me to replace the JPEG-based 'webcam' scripts and applet/ActiveX control with a true video streaming system using MPEG4/H263 compression and MP3 audio.
