Hi,
If your device has drivers & codecs to output RTMP/RTSP live stream in H.264/AAC format, the EMS can pull live streams directly from your device. Otherwise, you need software like FMLE or WireCast to output live streams using a protocol and format suitable for ingestion to EMS (*).
Alternatively, if your device has software that can capture to file formats compatible with EMS (*), you can use EMS to do Video-On-Demand or VOD streaming from the captured files.
One more option, is to use the Blackmagic Video SDK to develop software that sits between your device and the EMS. I wouldn’t recommend this, however, unless you have special reasons to do so.
(*) EMS-compatible protocols and formats are listed here:
