GStreamer Element Parameter Reference

To send video to the Amazon Kinesis Video Streams Producer SDK, you specify kvssink as the sink, or final destination of the pipeline. This reference provides information about kvssink required and optional parameters. For more information, see Example: Kinesis Video Streams Producer SDK GStreamer Plugin.

The kvssink element has the following required parameters:

• stream-name: The name of the destination Kinesis video stream.

  Note

  When using IoT authorization, the value of stream-name must be identical to the value of iot-thingname (in IoT provisioning). For more information, see "Invalid thing name passed" error when using IoT authorization.

• storage-size: The storage size of the device in megabytes. For information about configuring device storage, see StorageInfo.

• access-key: The AWS access key that is used to access Kinesis Video Streams. You must provide either this parameter or credential-path.

• secret-key: The AWS secret key that is used to access Kinesis Video Streams. You must provide either this parameter or credential-path.

• credential-path: A path to a file containing your credentials for accessing Kinesis Video Streams. You must provide either this parameter or access-key and secret-key.

The kvssink element has the following optional parameters. For more information about these parameters, see Kinesis Video Stream Structures.
