Thanks a lot for your help!
I just tried your command, Chap, but it still does the same for me:
Code:
$ rtmpdump -v -r "rtmp://ustreamlivefs.fplive.net/ustream1live-live/stream_live_1_1_2298576" -W "http://static-cdn1.ustream.tv/swf/live/viewer.rsl:368.swf" -y "stream_live_1_1_2298576" -o ~/tmp/live.flv
RTMPDump v2.4

Starting Live Stream

It stays ~10 seconds after "Starting Live Stream" and then it stops with the rest of the message.
I realized there was a problem with the -W parameter, but I think it is not related to my issue since it works with other streams even with this warning.
I am wondering if maybe the stream is simply not available at times... Ustream indicates certain channels as "offline", but it is weird because the original page (
http://www.ustream.tv/ffrc warning: video of cats

) is NOT "offline" right now, and I can watch the video in the broswer, so it must be something else...
Thanks again for your help.
