[vlc] Cannot stream via RTSP from Bitband VOD server

[Nick Hart]

Hi,

I am trying to stream an MPEG2 Transport Stream file from a Bitband Vision 280 VOD server.  For some reason this isn't working for me.  I have contacted Bitband support and they gave me some configuration changes to put into effect for VLC, but no change in behavior occurred.  I get neither video or audio and the Messages window says 'nothing to play'.

Here is the full output of the messages window:

I have also run an ethereal capture, but I have no way of pasting that in this message.  The quick rundown of it is that VLC and the Bitband server seem to negotiate the stream properly but then VLC sends a receiver report of type 'Goodbye' to the Bitband after the PLAY request comes through.  Bitband replies with a 'destination port unreachable' and starts to stream anyway.  But at this point, VLC seems to no longer be listening on the negotiated port(s) and gives destination unreachable messages back to the Bitband.

I have also tried running the VLC VOD server from the telnet interface and VLC will stream from that without issue.  This leads me to believe that there is a problem with the stream negotiation.  If anyone has any suggestions for me, I would appreciate hearing them.

Thanks!
