To run the Java test harness for the [Java producer library](https://docs.aws.amazon.com/kinesisvideostreams/latest/dg/producer-sdk-javaapi.html), do the following.

1. Choose **DemoAppMain**.

1. Choose **Run**, **Run 'DemoAppMain'**.

1. Add your credentials to the JVM arguments for the application:
   + **For non-temporary AWS credentials:** `"-Daws.accessKeyId={YourAwsAccessKey} -Daws.secretKey={YourAwsSecretKey} -Djava.library.path={NativeLibraryPath}"` 
   + **For temporary AWS credentials:** `"-Daws.accessKeyId={YourAwsAccessKey} -Daws.secretKey={YourAwsSecretKey} -Daws.sessionToken={YourAwsSessionToken} -Djava.library.path={NativeLibraryPath}" ` 

1. Sign in to the AWS Management Console and open the [Kinesis Video Streams console](https://console.aws.amazon.com//kinesisvideo/home/). 

   On the **Manage Streams** page, choose your stream.

1. The sample video will play in the embedded player. You might need to wait a short time (up to ten seconds under typical bandwidth and processor conditions) while the frames accumulate before the video appears.

The code example creates a stream. As the `MediaSource` in the code starts, it begins sending sample frames to the `KinesisVideoClient`. The client then sends the data to your Kinesis video stream.
