Hi,
Please try the following:
1. Use VLC to check your input stream. Run VLC, then click Media > Open Network Stream, enter the URI of your source stream, e.g. rtsp://192.168.1.195:554/ufirststream, then click Play. If it plays OK, click Tools > Codec Information to check the audio & video codecs of your input stream. Also, click the Statistics tab to check the bitrate of your input stream.
2. Check the running instances of EMS by typing "ps -ef | grep evo".
3. Check port 6666 by typing "netstat -taupen | grep 6666".
Compare the results on your virtual and physical machines. There may be differences in your config.lua also.
Cheers,
Don
