Input with RTMP or SRT protocols

Our platform allows sending either the primary or secondary (or both) contribution streams via the RTMP or SRT protocols instead of icecast. This allows easier integration with third-party tools and platforms, especially when repurposing video streams into audio-only broadcasts. Both of these protocols are popular in video stream delivery workflows.

Get RTMP or SRT contribution URLs

To start sending audio using these formats, visit the stream page and under the "Setup" section of the admin panel, look for the "Alternative inputs" section. Use the the "Copy to clipboard" functionality to get the stream URL to use.

Example URL structure:

• RTMP URL: rtmp://<yourip>:1935/<stream-id>_primary
• SRT URL: srt://<yourip>:9998?mode=caller&passphrase=<yourpassword>

RTMP

The Real Time Messaging Protocol is the most mature and widely used protocol for delivering video over the internet.

Example: setup RTMP input with Restream.io

• Choose "Add Channel"
• Choose "Custom RTMP"
• Use the RTMP URL copied from the stream dashboard.
• For "Stream key" use the "Password" from the "Input Settings" section.
• Leave "Use Authentication" disabled.

Example: setup RTMP input with OBS

• Under "Settings / "Stream" choose "Custom..." service.
• Use the RTMP URL copied from the dashboard as "Server"
• For "Stream key" use the "Password" from the "Input Settings" section.
• Leave "Use Authentication" disabled.

Troubleshooting RTMP

Service fails to connect. Ensure the "URL" is correctly copied from the dashboard.
Service connects but no audio being received. Ensure the "Source key" setting is set correctly to the password.

SRT

The Secure Reliable Transport protocol is designed to deliver low-latency audio/video streams over public and private networks.

Example: setup SRT input with OBS

• Under "Settings / "Stream" choose "Custom..." service.
• Use the SRT URL copied from the dashboard as "Server"
• Leave "Stream Key" empty and "Use authentication disabled.
