I can’t get this working.
So i’ll started to do some independent test.
installed VLC player and then put my camera rtsp stream into VLC.
Getting this message: vlc can’ t open rtsp://userxxxx:pwxxxxx%@192.168.1.241:xxxx/Videomain.

next stream in VLC plays perfect
rtsp://184.72.239.149/vod/mp4:BigBuckBunny_115k.mov

then I installed OMXplayer
Loaded following stream:

//sudo omxplayer -o hdmi rtsp://JSTAL:xxxxx@192.168.1.241:1052/videoMain

This works fine, full videoscreen of my IPcam.

then I modified config as follows

//{
		            module: 'MMM-RTSPStream',
			    classes: 'default everyone',
		            position: 'middle_center',
		            config: {
		                autoStart: true,
		                rotateStreams: false,
		                rotateStreamTimeout: 10,
		                showSnapWhenPaused: false,
		                moduleWidth: 354,
		                moduleHeight: 240,
				localPlayer: 'omxplayer',
		                stream1: {
		                    name: 'Webcam 1 Test Stream',
		                    url: 'rtsp://JSTAL:xxxxxxxx@192.168.1.241:1052/videoMain',
		                    snapshotUrl: '',
		                    snapshotRefresh: 10, // Seconds
		                    frameRate: "25",
		                    port: 9999,
		                }
		            }
      		  },

conclusion so far, installed software is OK

‘xxxxx’ in the rtsp stream is where i put my password.
password contains special char ‘%’ - can the be the reason of VLC not showing the stream.

so i’m stuck…
any idea’s to solve are welcome.
