Create restream

Creates a new restream for a specified live stream.

Specify the target platform’s URI (RTMP, RTMPS, or SRT) and the ID of the source stream.

Restreaming allows you to broadcast a single live stream to multiple platforms or servers simultaneously (e.g., Facebook, YouTube, or a custom media server).

How it works:

1. Get credentials (stream URL/key or SRT URL) from the target platform.
2. Create a restream in the Gcore system by specifying the target URI and the source live stream.
3. Start your live stream; it will be automatically pushed to the target destination.

                +-----------------------+
RTMP/RTMPS      |                       | -------->  Facebook (RTMP)
    or  ------> |    Gcore Streaming    | -------->  YouTube (RTMPS)
SRT             |                       | -------->  Media server (SRT)
                +-----------------------+ -------->  Other RTMP/SRT targets

Supported combinations: RTMP → RTMP, RTMPS → RTMPS, RTMP → SRT, SRT → SRT, SRT → RTMP. For SRT targets, only mode=caller is supported (Gcore initiates a PUSH connection).

Source stream parameters (bitrate, codecs, resolution) are sent “as is”. Ensure they match the destination requirements.
