Before I go ahead and report a bug I want to double check if this is the expected behaviour for an RTP stream that is being opened in VLC 0.9.8 (Intel).
The RTP stream I'm joining is on 239.192.2.40, port 3000.
If I use the default options from the GUI, Radio button UDP/RTP Multicast, this generate the following Media Resource Locator (MRL): udp://@239.192.2.40:3000
The outputted video is all garbled and will crash VLC between seconds and minutes.
I have to override the MLR with rtp://@239.192.2.40:3000 for the stream to be processed correctly.
Since there is no drop down list as there is for the Windows version, I can't specifically select RTP under OS X.
IMHO this is a bug that needs to be fixed.
