import boto3
from uuid import uuid4
import json

client = boto3.client("chime-sdk-media-pipelines", region_name='us-east-1')
pool_name = 'MyDemoKvsPool'

def pretty_print_json(obj):
    print(json.dumps(obj, default=str, indent=4))
```

## CreateMediaPipelineKinesisVideoStreamPool


```
response = client.create_media_pipeline_kinesis_video_stream_pool(
        StreamConfiguration={
            'Region': 'us-east-1',
            'DataRetentionInHours': 24
        },
        PoolName=pool_name,
        ClientRequestToken=str(uuid4()),
        Tags=[
            {
                'Key': 'MyTagForAccessControl',
                'Value': 'SomeTagValue'
            },
        ]
)

pretty_print_json(response['KinesisVideoStreamPoolConfiguration'])
```

**Output**:

```
{
    "PoolArn": "arn:aws:chime:us-east-1:account-ID:media-pipeline-kinesis-video-stream-pool/MyDemoKvsPool",
    "PoolName": "MyDemoKvsPool",

    "PoolStatus": "CREATING",
    "StreamConfiguration": {
        "Region": "us-east-1",
        "DataRetentionInHours": 24
    },

    "UpdatedTimestamp": "2023-10-13 01:26:09.979000+00:00"
}
```

## GetMediaPipelineKinesisVideoStream


```
response = client.get_media_pipeline_kinesis_video_stream_pool(
        Identifier=pool_name
)

pretty_print_json(response['KinesisVideoStreamPoolConfiguration'])
```

**Output**:

```
{
    "PoolArn": "arn:aws:chime:us-east-1:account-ID:media-pipeline-kinesis-video-stream-pool/MyDemoKvsPool",
    "PoolName": "MyDemoKvsPool",

    "UpdatedTimestamp": "2023-10-13 01:26:09.979000+00:00"
}
```

## UpdateMediaPipelineKinesisVideoStream


```
response = client.update_media_pipeline_kinesis_video_stream_pool(
    Identifier=pool_name,
    StreamConfiguration={
        'DataRetentionInHours': 48
    }
)
pretty_print_json(response['KinesisVideoStreamPoolConfiguration'])
```

**Output**:

```

    "PoolArn": "arn:aws:chime:us-east-1:account-ID:media-pipeline-kinesis-video-stream-pool/MyDemoKvsPool",
    "PoolName": "MyDemoKvsPool",
    "PoolId": "ChimeMediaPipelines-MyDemoKvsPool-d08c26ae-0336-4e2e-acdf-805a7d71b891",
    "PoolStatus": "UPDATING",
    "PoolSize": 40,
    "StreamConfiguration": {
        "Region": "us-east-1",
        "DataRetentionInHours": 48
    },
    "CreatedTimestamp": "2023-10-13 01:44:23.010000+00:00",
    "UpdatedTimestamp": "2023-10-13 01:44:28.486000+00:00"
}
```

## ListMediaPipelineKinesisVideoStream


```
list_of_pools = []
max_results = 100
next_token = None
while(True):
    if next_token:
        response = client.list_media_pipeline_kinesis_video_stream_pools(
            NextToken=next_token,
            MaxResults=max_results
        )
    else:
        response = client.list_media_pipeline_kinesis_video_stream_pools(
            MaxResults=max_results
        )

    list_of_pools.extend(response['KinesisVideoStreamPools'])
    next_token = response.get('NextToken')
    if not next_token:
        break
pretty_print_json(list_of_pools)
```

**Output**:

```
[
    {
        "PoolName": "MyDemoKvsPool",
        "PoolId": "ChimeMediaPipelines-MyDemoKvsPool-6588e703-f046-4288-ba7f-0c03de76a6bb",
        "PoolArn": "arn:aws:chime:us-east-1:account-ID:media-pipeline-kinesis-video-stream-pool/MyDemoKvsPool"
    }
]
```

## DeleteMediaPipelineKinesisVideoStream


```
client.delete_media_pipeline_kinesis_video_stream_pool(
    Identifier=pool_name
)
```

**Output**: A successful `delete_media_pipeline_kinesis_video_stream_pool` request has no body.
