Hi,
Please check the codec(s) used by your RTSP camera. In VLC, click Tools > Codec Information to see the codec(s) used. The video codec should be H.264 (and, if audio is present, the audio codec should be AAC) for compatibility with EMS. If not, you can use the EMS transcode command to convert your stream to H.264/AAC so that it can be used by EMS. For details on the EMS transcode command, please refer to the EMS API Definitions and EMS User Guide: https://evostream.com/support/documentation/
Cheers,
Don
