capo-kinesis-video-media: typed, async Python SDK for AWS Kinesis Video Media¶

capo-kinesis-video-media is a typed Python SDK for AWS Kinesis Video Media. It has an async client, AsyncKinesisVideoMediaClient, for asyncio and trio, and a sync client, KinesisVideoMediaClient, with the same methods. Requests and responses are typed with TypedDicts, so your editor and type checker know every field.

It is part of capo, a community-driven alternative to boto3 and aioboto3, built on its own HTTP stack instead of botocore and generated from the official AWS Smithy models. Documentation: https://capo-sdk.dev/services/kinesis-video-media/

Installation¶

pip install capo-kinesis-video-media

Usage¶

from capo_kinesis_video_media import AsyncKinesisVideoMediaClient


async def main():
    async with AsyncKinesisVideoMediaClient() as kinesis_video_media:
        # Example: call the get_media operation
        response = await kinesis_video_media.get_media()
        print(response["content_type"])

Streaming Response¶

Some operations return a streaming response body. Use the operation as an async context manager and iterate over the response field to read chunks.

from capo_kinesis_video_media import AsyncKinesisVideoMediaClient


async def main():
    async with AsyncKinesisVideoMediaClient() as kinesis_video_media:
        # Example: call get_media and read the streaming response
        async with kinesis_video_media.get_media() as response:
            async for chunk in response["payload"]:
                print(chunk)

Error Handling¶

The SDK raises exceptions for errors returned by the API. Catch them to handle failures gracefully.

from capo_kinesis_video_media import AsyncKinesisVideoMediaClient
from capo_kinesis_video_media.error import ClientLimitExceededException


async def main():
    async with AsyncKinesisVideoMediaClient() as kinesis_video_media:
        try:
            await kinesis_video_media.get_media()
        except ClientLimitExceededException as e:
            print(f"Error: {e}")
            print(e.data)  # additional error data

Retrying¶

The SDK retries failed operations automatically. Retry behaviour follows the Smithy specification: errors are retried based on their is_retryable and is_throttling_error attributes. Throttling errors use a longer base delay. Network-level failures (connection errors and timeouts) are also retried. Non-retryable errors, such as client errors without the @retryable trait, are raised immediately without further attempts.

The number of attempts defaults to 3 and can be changed at the client level via retry_max_attempts, or per call via config_overrides.

from capo_kinesis_video_media import AsyncKinesisVideoMediaClient


async def main():
    async with AsyncKinesisVideoMediaClient() as kinesis_video_media:
        # Default: 3 attempts for every operation
        response = await kinesis_video_media.get_media()

        # Override per operation
        response = await kinesis_video_media.get_media(config_overrides={"retry_max_attempts": 5})

        # Disable retries for this call
        response = await kinesis_video_media.get_media(config_overrides={"retry_max_attempts": 1})
