[Ambulant-users] Ambulant not playing RTSP feeds.

There are a number of issues with rtsp. Some are our fault, others are problems with the way rtsp servers are setup and general problems with rtsp. And it could indeed be the case that there is a build problem too.
First thing to check is that your build includes live555. Check the configure log, and if live555 wasn't included fix that and try again. Live555 is required for ambulant to be able to play rtsp.
Next thing to check is that there isn't a problem with the encoding of your file (triggered by the no suitable codec message you report): try and copy the media from the rtsp server to a local file and check that ambulant can play it back then.
If local playback does work you may be running into a shortcoming of ambulant: it doesn't do automatic switching between UDP and TCP as transport mechanisms. So if you there is a firewall between the client machine and the rtsp server you have to manually enable tcp transport in the ambulant settings. Fixing this is on our to do list, but it is not very high priority.
If that still doesn't work: please set log level in ambulant to "debug", and send us both the log output and your smil document.

Now after selecting "use ffmpeg instead of direct draw" the test SMIL video shows the rtsp feed of the man turning the torch on, however when trying to play our local rtsp feeds, it still fails to render the feeds with the following errors:
> "rtsp://my.local.domain:port/udpstream_ch1_stream1: Ignoring audio, No suitable codec" or something similar, however I think this only pertains to the audio.
