How to get producer and server timestamp of each frame from boto3 kvam.get_hls_streaming_session_url

Hey, I am currently using boto3's kvam.get_hls_streaming_session_url to get the url of the kinesis video stream as show in this here https://aws.amazon.com/blogs/aws/amazon-kinesis-video-streams-adds-support-for-hls-output-streams/ and am using cv2.videocapture and pass kinesis url to get each frames. But I would like to get the producer and server timestamp of each frame. Is there any way to get it?
