Manage Output Streams

Add outputs for stream conversion, so that Control Hub may deliver videos to target destinations with different formats without changing the original contents. Outputs of RTMP/RTMPS/RTSP/SRT Caller/SRT Listener/TS over UDP/TS over RTP are supported.

You can add up to 300 outputs in the Presets page.

  1. Enter the Streaming > Outputs page from the navigation pane.
  2. Click to add target destinations. And save after configuration.
    • Add a RTMP output.

      Parameters

      • Name: specify a case-insensitive name containing 1 to 64 characters for current task to facilitate outputs management, which will be displayed in the presets.
      • URL: enter the target RTMP/RTMPS URL address.
      • Stream key: enter the stream key obtained from the destination.
      • Authentication: turn the switch on and set the Username and Password to protect your data and satisfy your needs.
    • Add a RTSP output.

      Parameters

      • Name: specify a case-insensitive name for current task to facilitate output management, which will be displayed in the presets list. The range is 1 to 64 characters.
      • Port: specify RTSP stream port, the range is 1 to 65535 and the default is 554.
      • Stream key: set the stream key containing 1 to 63 characters to protect your data.
      • Connections: set number of clients for RTSP, 1 to 50 clients are supported. By default, it is 30.
      • Authentication: turn the switch on and set the Username and Password to protect your data and satisfy your needs.

    • Add an SRT Caller/Listener output

      Parameters

      • Name: specify a case-insensitive name for current task to facilitate output management, which will be displayed in the presets list. The range is 1 to 64 characters.
      • Address: available for SRT Caller. If the SRT listener and caller are on the same LAN, enter the private IP address of the SRT listener on the LAN. If the SRT listener and caller are in different network environments, enter the public IP address of the SRT listener.
      • Port: the range is 1 to 65535. The port number must be the same as the destination's.
      • Stream ID: available for SRT Caller. 0 to 256 characters which should be consistent with that of its destination's.
      • Latency: the range is 20 to 8000ms. The default value is 120. We recommend that you set the same latency for SRT pull and push.
      • Bandwidth: indicate the portion of the total bandwidth of a stream required for the exchange of SRT control and recovery packets. A worse network condition requires more bandwidth for overhead to ensure normal transmission. It is mandatory. The range is 5 to 100 in Percentage. The default value is 25%.
      • MTU: specify maximum transmission unit (MTU) in bytes, ranging from 232 to 1500. The default size is 1500.
      • Connections: set number of clients for SRT Listener, 1 to 50 clients are supported. By default, it is 30.
      • Encryption: specify the stream encryption algorithm to ensure the data security, options are AES-128/192/256. Then specify a Passphrase containing 10 to 79 characters. By default, it is not encrypted.

    • Add a TS over UDP/TS over RTP output

      Parameters

      • Name: specify a case-insensitive name for current task to facilitate output management, which will be displayed in Presets list containing 1 to 64 characters.
      • Mode: Unicast indicates that the Control Hub sends a stream directly to the receiver which works when lower latency matters. Multicast indicates that the Control Hub multicasts streams to multiple destinations which works for one-to-many broadcast with lower CPU utilization.
      • Address: multicast address ranges from 224.0.0.0 to 239.255.255.255. Unicast address can be IP address or domain name.
      • Port: range is 1 to 65535.
      • MTU: specify maximum transmission unit (MTU) in bytes, ranging from 228 to 1500. The default size is 1496.
  3. Move the cursor to an output in the Presets, then you can
    • click Edit to modify the output parameters.
    • click X to delete current output.
