Use the information provided in the properties group to choose the appropriate configuration.

Video Capture

Device name — VLS4 device mapping

/dev/video0 (default) | hardware path of video device

This parameter specifies the VLS4 video device to use in the generated code as a Linux hardware path.

Video Display

Display title — Title of video display

My Display (default) | string

This parameter specifies the title of the video viewer shown on the screen of a connected monitor.

Audio Capture

Device name — ALSA device mapping

hw:2,0 (default) | hw:X,Y

This parameter specifies the ALSA hardware card, X, and device, Y, mapping on the embedded Linux device.

Audio sampling frequency — Sampling frequency of audio device

44100 (default) | positive scalar integer

This parameter specifies the audio sampling frequency of the device managed by the ALSA driver. The selected value must be supported by the embedded Linux peripheral device.

Audio Playback

Device name — ALSA device mapping

hw:2,0 (default) | hw:X,Y

This parameter specifies the ALSA hardware card, X, and device, Y, mapping on the embedded Linux device.

Audio sampling frequency — Sampling frequency of audio device

44100 (default) | positive scalar integer

This parameter specifies the audio sampling frequency of the device managed by the ALSA driver. The selected value must be supported by the peripheral device and the ALSA driver on your embedded Linux device.
