How to Create and Assign Inputs

Learn how to create RTMP or SRT inputs, assign them to streams, and troubleshoot issues, since a stream cannot start without an input assigned.

Overview

Inputs are the video feeds coming into LIGR Live from your camera or streaming software. Every stream requires one input assigned before it can start. You create inputs in the Streaming tab, then assign them to streams when setting up matches.


You'll use inputs when setting up a new stream for a match, when connecting a camera or encoder to LIGR Live, and when troubleshooting why a stream won't start.


Key Concepts

An Input is the video feed coming into LIGR Live from your camera or streaming software, and each stream requires one input. RTMP is a streaming protocol that uses an RTMP URL and stream key to connect your video source to LIGR Live, while SRT is a streaming protocol that uses a single SRT link to do the same. Input Assignment is the process of linking an input to a specific stream, with one input allowed per stream.


How to Create an Input

To create a new input, start by clicking Streaming in the left sidebar, then navigate to the Inputs section and click Create Input. Next, select the input type: RTMP, which uses an RTMP URL and stream key, or SRT, which uses a single SRT link. Enter a descriptive name for the input (e.g., "Main Camera", "Field Camera"), then click Create. The input is now created and will appear in your inputs list.

How to Access Input Details

After creating an input, you need the connection details to configure your camera or streaming software.


For RTMP Inputs: click on the input in your inputs list, copy the RTMP URL, copy the Stream Key, then enter both into your streaming software or camera encoder.


For SRT Inputs: click on the input in your inputs list, copy the SRT link, then enter the link into your streaming software or camera encoder.


You can also access input details from the Stream Monitoring page (Stream View) on the left side under Input information.


How to Assign an Input to a Stream

Inputs must be assigned to streams before those streams can start.


When Creating a New Stream: navigate to Matches and find your match, then click the drop-down arrow to expand match details and click Add Stream. In the Stream Input field, select your input from the dropdown, complete the remaining stream configuration, and click Create.


For an Existing Stream: navigate to Matches and find your match, click the drop-down arrow to expand match details, then click anywhere in the white space of the stream row to open the side panel. In the Input Assignment section, select your input from the dropdown.


Alternatively, click the three-dot Actions menu next to the stream and select Configure. In the Stream Input field, select your input from the dropdown, then click Save.


Note: The stream must be stopped before you can change the input assignment.

Understanding Input Indicators

Input status indicators appear in the Matches table and Stream Monitoring page. A gray indicator means the input has been created but is not receiving video, while a red indicator means the input is receiving a video feed. Bitrate indicators also help: a warning icon means no stream is being received, while a green indicator with a KBS value means a stream is being received.


Why Streams Cannot Start Without Inputs

LIGR Live streams require a video source to broadcast. If no input is assigned to a stream, there is no video to send to destinations. When you try to start a stream without an input assigned, a gray warning icon appears on the input indicator, the Start Stream button may be unavailable, and the stream cannot initialize. Always verify an input is assigned before attempting to start a stream.


Connections to Other Sections

Matches Section: Inputs are assigned to streams when configuring matches. Stream settings in the Matches section include input assignment.


Multiview: The Multiview shows input status indicators for all active streams, allowing you to monitor which inputs are receiving video.


Stream Monitoring Page: Input details (RTMP URL and stream key, or SRT link) are accessible from the Stream View page on the left side under Input information.


Common Issues and Solutions

Issue: Stream won't start. Check for a gray warning icon on the input indicator. This means no input is assigned to the stream. Assign an input to the stream and try starting again.


Issue: Input indicator shows gray (not receiving video). Verify your streaming software or camera is configured with the correct input details (RTMP URL and stream key, or SRT link). Start the stream in LIGR first, since LIGR must be in a live state to receive the incoming feed, then start sending video from your encoder.


Issue: Cannot change input assignment. The stream must be stopped before you can change the input assignment. Stop the stream, change the input, then restart it.


Issue: Input details not working in streaming software. Verify you copied both the RTMP URL and stream key (for RTMP inputs) or the complete SRT link (for SRT inputs). Check that the LIGR stream is started before sending video from your encoder.
