This is the first result of our live stream testing with the trunk - the svn 0.6 dev trunk is the same as 0.6RC2 isn't it?:
Server: AMD64 3000+ Fedora Core 4 Linux 2 GIG RAM 1 GIG Internet connection in data center One live publisher and one subscriber Both publisher and subscriber are remote (on a cable modem) Publisher: 1 GIG Processor 512 Meg RAM Windows 2000 16 fps 80% quality 320x240 audio 22 khz overall bandwidth 370 kbps Initial Stats: 465 Meg RAM in use 0 Swap in use virtually no CPU load Stream delay < 2 seconds After approximately 2 hours the stream froze and the upload and download bandwidth went down to 0. There was no significant change in RAM or CPU stats. At the time of freezing, the live stream had gradually built up an overall delay of 10 seconds. Both audio and video were still in sync with each other. We noticed a few minor hiccups during the 2 hours of successful streaming where the video and audio would freeze for a second and then come back. Restarted the publisher Flash movie. The subscriber started working without any intervention once the publisher was back from it's restart.
