Hi,
it is has been some time since I used MMM-RTSPStream, but you can try following and provide some more info.
$ which omxplayer
$ vcgencmd codec_enabled MPG2
omxplayer only logs when asked for (–genlog).
Try running omxplayer from the command line first:
$ cd
$ rm -f omxplayer.log
$ omxplayer --genlog --win "0 0 800 480" rtsp://admin:*******@192.168.1.242
or:
$ omxplayer --genlog --avdict rtsp_transport:tcp --live --video_queue 4 --fps 30 --win "0 0 800 480" rtsp://admin:*******@192.168.1.242
$ ls -als omxplayer.log
$ sudo find . -name omxplayer.log
And it appears you have a few mistakes / omitted parameters in your config.js:
moduleWidth: 590,
moduleHeight: 332,
ffmpegPort: 9999,
width: 590,
height: 332,
port: 9999,
is not a valid parameter.
Furthermore, your URL seems a bit basic, but that probably depends on the camera.
For example, for my Axis camera I need this:
rtsp://user:password@192.168.178.56/axis-media/media.amp?resolution=640x360
