Preset
There are six predefined presets. If you edit any control options, preset the mode switches
to Custom. See Table 3-2.
Output Options
This option allows you to select the sink for the pipeline. Supported output sink types are:
•DisplayPort
•Record
•Stream Out
For the DisplayPort output option, either the enc-dec Codec or Pass-through option can
be selected.
For the Record and Stream Out output options, only Encode can be selected in Codec.
Demo Mode
By clicking on this button, the button text state changes to stop and you can play all
pipelines (TPG, MIPI, HDMI) with raw and preset configurations.
Every ten seconds, playback preset changes and plays in a loop until you click the stop
button.
If no source is connected, an error popup displays.
If any error returns in any playback, the demo skips and continues to play other pipelines.
