troubles with kinesis video streams to S3 bucket for image generation process

hello. i've been trying sending realtime video stream through raspberrypi with webcam to kinesis video stream and want to transform it and save the continous images(not a video). i checked the youtube video from AWS iot (https://www.youtube.com/watch?v=YoOYTCD_v3Q, https://www.youtube.com/watch?v=pUvxI76YnfA) and successed getting video stream from raspberrypi to kinesis video stream(Iot core certification). But, the thing is i followed instruction and it cannot connect with S3(cannot save images in S3 bucket). i've double checked the role and policies which is same as instructions.

{
    "StreamName": "rt-video-1",
    "ImageGenerationConfiguration":
    {
     "Status": "ENABLED",
     "DestinationConfig":
     {
      "DestinationRegion": "ap-northeast-2",
      "Uri": "s3://dining-images/rt-video-1/"
     },
     "SamplingInterval": 2000,
     "ImageSelectorType": "PRODUCER_TIMESTAMP",
     "Format": "PNG",
     "WidthPixels": 640,
     "HeightPixels": 480
    }
   }

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": [
                "kinesisvideo:DescribeStream",
                "kinesisvideo:PutMedia",
                "kinesisvideo:TagStream",
                "kinesisvideo:GetDataEndpoint"
            ],
            "Resource": "arn:aws:kinesisvideo:*:*:stream/${credentials-iot:ThingName}/*"
        },
        {
            "Effect": "Allow",
            "Action": [
                "s3:*",
                "s3-object-lambda:*"
            ],
            "Resource": "arn:aws:s3:::dining-images/*"
        }
    ]
}

are these all information where kinesis video stream and S3 bucket is connected? please tell me where might be wrong
