Before proceeding, you must stop the Channel by deactivating the checkbox. Stopping the channel will also stop the Just Live Lite playout engine.
After using the New Channel Wizard, the engine named “Primary” is automatically created and added to all Layers of the Channel, using the settings defined in the Wizard.
Change the engine configuration
Do the following to change the settings of the Just Live Lite playout engine:
Stop the Channel by unchecking the checkbox in front of it. Stopping a Channel will also stop the Just Live Lite playout engine. and therefore the final output.
Select the Channel in the “Devices & Channels” list.
Click on the “Layers & Engines” tab.
Click on the Engine name and select “Configure Engine”.
Setup tab
Provides general settings related to the Just Live Lite playout engine.
Name: Allows you to change the name of the engine.
Network: Engine network configuration.
IP address: Shows the IP address of the internal engine.
Port: Port that is used by the internal engine.
Heartbeat Timeout: Defines the number of heartbeats which can be missed, before the engine is defined as stopped. This can be useful in setups, where the heartbeat is missing due to an unreliable network.
Video device & output: Mode for the final video output.
Virtual: Use this if no dedicated video hardware is available for the final output on this machine.
AJA: In case you have an AJA device installed and you would like to use this device as the output device.
Blackmagic: In case you have a Blackmagic Design device installed and you would like to use this device as the output device.
NDI: Selecting NDI lets you receive an NDI® stream as a live input and stream the final output as an NDI® signal using the network your machine is connected to.
SRT: Selecting SRT lets you receive an SRT stream as a live input and stream the final output as an SRT signal using the network your machine is connected to.
UDP: Selecting UDP lets you receive a UDP stream as a live input and stream the final output as a UDP signal using the network your machine is connected to.
Preview: Defines the Preview quality shown in the On Air window of the user interface.
Frame-rate: Allows you to specify the number of frames per second for the video Preview. This should never be higher than the native frame rate of the Channel.
Resolution: This defines the number of pixels used for the Preview. Select from one of the available values.
Quality: This defines the amount of compression that is applied to the uncompressed image before it is used for the Preview.
Streaming tab
This tab provides the settings in case one of the streaming formats has been selected for playout.
Additionally, when configuring and channel with NDI® live input, there is an “NDI Timecode Mode” setting in the “Streaming” tab in the engine’s configuration panel with the options “NDI UTC Timestamps” and “SMPTE Timecode”. The former expects frames with standard NDI UTC timestamps, as provided by the majority of NDI devices. The latter expects SMPTE timecode encoded as 100ths of a nanosecond. This may be useful in conjunction with some devices such as the AJA Bridge that take embedded SDI SMPTE timecode and converts it for use with NDI.
SRT: Selecting SRT lets you receive an SRT stream as a live input and stream the final output as an SRT signal using the network your machine is connected to.
UDP: Selecting UDP lets you receive a UDP stream as a live input and stream the final output as a UDP signal using the network your machine is connected to.
Configure Encoder
Click on the “Configure Encoder” button, to open the encoder settings window.
H.264 video:
Profile/level: Select the profile which should be used for the H.264 encoding.
Bit rate: Define the video bit rate, in kbps, the outgoing stream should have.
AAC audio:
Define the audio bit rate, in kbps, the outgoing stream should have.
