I have a stream that was currently working earlier this morning but now isn't being encoded correctly by our Wowza Streaming Engine. Currently it just shows black so it is receiving information just not encoding it correctly I suppose.
Looking at direct playback in VLC of your source, the stream is h.264 video, which is great, but the audio is PMC MU-LAW (aka g.711) according to VLC (Tools > Codec Info). That might work in Flash RTMP and HDS clients, but I don't think it will work in HLS or smooth. It might work in RTSP. I will test your stream, hold on...
I am able to re-stream your source and playback in Flash RTMP and Flash HDS. It's not clear if the audio works. It does packetize for HDS. I don't hear audio, but there may not be any sound where the camera is
The audio does not packetize for HLS, but it should work in HLS playback anyway. You can remove the audio by using a .stream file like this:
Make sure you have added your .stream file to StartUpStreams in the manager or in /conf/StartUpStreams.xml, and test in the Flash RTMP or HDS player. You need to enable the sanjosestreamingpacketizer in Application.xml /Streams /LiveStreamPacketizers for HDS playback.
