When service "SRT Streamer PRO" is running (see here) then you can go to "http://127.0.0.1:8082" in browser.
Workflow is:
1) create streaming profile in section "Streaming Setup". Profile includes info about target server and encoding params. You can add many profiles for example for stream to few servers.
2) add one or more Stream. Each Stream contains information about source (for example SDI input) , the profile being used and additional info like "stream id"
3) start each Stream or all by button "Start all".
Step 1: Streaming Setup
In this window you need setup Destination host/port and parameters for streams.
SRT Streamer PRO will be capture sources and converts every feed to this format, encode and send to Destination server.
Press button "Add stream". In this window select Profile, source and type stream id. When this stream will be started then it will use params from Profile (destination server, fps, bitrate etc).
