@tableofcontents

@note SW Release Applicability: This sample is available in both **NVIDIA DriveWorks** and **NVIDIA DRIVE Software** releases.

@section dwx_image_streamer_cross_description Description

The Cross-Process Image Streamer sample demonstrates how to use an image
streamer across multiple processes.

@section dwx_image_streamer_cross_running Running the Sample

The command line for the sample is:

    ./sample_image_streamer_cross --type=[consumer|producer]

where

    --type=[consumer|producer]
        When in consumer mode, the sample waits for a producer.
        Two instances of this sample have to be executed, and the
        consumer instance has to be started first.
        Default value: consumer

@note In case the producer is launched first, do not kill the process,
simply wait for it to timeout.

@section dwx_image_streamer_cross_output Output

When consumer is running, after launching the producer, the sample creates a window
and renders received frames on screen.
