Selector and Choice Tools
The Selector and Choice tools let you define a condition to choose the
input or output that should be used, respectively. They are both built the
same way.
Dialog Description
The dialog contains two parts.
Parameter
Create a parameter to be used in the condition : check the box if
you want the job’s author to set a parameter that will be used in the
condition to choose the output. Edit the cells to create the parameter.
Conditions
The array lets you set a condition for each output. Double-click in the
Condition column or click the button to access the condition editor.
This editor is described in section ’Processing Component Parameters
Array’ on page 232.
You can add inputs or outputs if needed.
Choice
The Choice tool lets you define a condition to choose the output that
should be used. For example, let us imagine you want to send the stream
to a different output based on the input bitrate, e.g. send it to output A if
the bitrate is lower than 80,000 kbps, and to output B if it is higher.
To use the Choice tool, you first need to have in your workflow a public
parameter with a label. For our example, publish and give a label to the
bitrate parameter in the input processing component.
Insert the Choice processing component in your configuration and link
it to the preceding processing component.
