Device and Input
When the just:in linux appliances appliance is running with multiple Video Devices, you can choose the Video Device and the Video Device Input for this Channel here.
...
With the Video Encoder Threads setting you can adjust how many CPU cores the Channel will use for the encoding process. This setting was especially designed for multi-channel UHD/4K recording. Please only change this setting, after consulting a ToolsOnAir Support Engineer.
AJA Frame Buffer
This setting adjusts the internal Frame Buffer of each individual AJA input source. This setting was designed to improve the stability and performance for UHD/4K recording workflows. Please consult a ToolsOnAir Support Member, before changing this setting.

be very careful when changing the following three settings:
Please only change it, when consulting a ToolsOnAir support member before. |
CPU Affinity
This setting can be used to pin the Channel to specific CPUs, in order to gain performance improvements.
Capture Thread
The Capture Thread setting defines a specific CPU core for loading the video frames from the AJA capture device to the OS. This setting is important for cases, where the Channel dropped frames.
Write Thread
The Write Thread setting is similar to the Capture Thread setting and is used for setting a specific CPU core for handling the I/O process (=writing to the destination(s)).
