live555 error: Failed to connect with rtsp

[alank]

I have checked similar posts but can't see a solution as yet so maybe someone can steer me in the right direction.

I have been successfully connecting to this RTSP stream for a number of weeks but this week it failed to connect. I can connect to the same streaming source via my browser okay, so the streaming is working. I can also connect to other streaming via VCL although they are not RTSP format. I was using vcl-2.0.5-win32 but upgraded to vcl-2.0.8-win32 in an effort to fix the problem - no luck there. I have email the community FM station to ask if they have changed anything but haven't heard back - they have FM transmission problems after a lightening strike on the antenna so their minimal resources are occupied elsewhere.

OS Win8 - 64

Here is a VCL log of what is happening when attempting to connect

At the same time I used WireShark to capture the packet flow - don't understand much of this but was getting sumcheck values of '0' (Len=0). It may be of use.

In WireShark you can 'Follow the Stream' and this is what it says..

Any help would be greatly appreciated - My thanks in advance!

live555 debug: connection error 403

Solved.

I have found a HTTP source that is now working.

Yeah, I saw that error but just thought it was due to the HTTP tunneling. I assume this error is coming from the transmission source but I don't understand why the RTSP stream had work fine over a number of weeks and then came to an abrupt halt.

Anyway thanks for you help. I seemed to have learned a few other things about how streaming works and after installing RealPlayer in an attempt at a fix that it is a PIA to use ... and all those ads. Will dump it now.
