I noticed that the VLC I put on my fire keeps putting "http://" infront of the rtsp. Could that be why it will not connect?
I think that could be the problem. VLC and the Uniden dongle need the RTSP transport layer and not HTTP.
I know there is a way to use VLC on a PC and re-stream the RTSP/RTP data back out via HTTP and then the VLC you put on your Fire may work but I know doing that does add more delay plus you need to connect with VLS from a PC first before you can re-stream the audio back out over HTTP.
Somewhere, there is a thread or info in an existing thread that explained in detail how to setup VLC on a PC so it re-streamed thee RTSP audio.
Using that method, you would then make a connection to your PC instead of the dongle.
I'm not real familiar with the Kindle Fire but does it run Windows programs?
If so, Bob, the author of ProScan, released an early version of an RTSP/RTP streaming application that runs nicely on a PC.
It does not have all the bells and whistles that VLC has like neat eye candy spectrum scopes for the audio and such but it works and it works very well for streaming the audio.
When you start Bob's RTSP application, it shows you the ports that are used between it and the dongle which makes opening up and forwarding ports to your dongle very easy for those that wish to stream when away from their local network.
It's a very handy and simple RTSP/RTP streaming app that Bob put together.
