media-sdk-m8 0.1.0

Shared, settings-agnostic media primitives (object storage + job contracts) for m8 media services.

media-sdk-m8

Shared, settings-agnostic media primitives for the m8 media stack. Consumed by:

• media-service-m8 — the live API (job producer)
• media-worker-m8 — the async ARQ worker (job consumer)

The SDK is framework-agnostic (no FastAPI, no auth-sdk, no pydantic-settings) and imgtools-free. It owns no business logic, no database, and no preset knowledge — callers pass an explicit config object; the SDK never reads settings or env.

Contents

Object storage — media_sdk_m8.storage

ObjectStorage is a thin wrapper over the MinIO SDK. It is constructed from an explicit ObjectStorageConfig (endpoint, credentials, region, TLS, and the default presigned-URL lifetime), so it has no dependency on any service's settings module.

from media_sdk_m8 import ObjectStorage, ObjectStorageConfig

config = ObjectStorageConfig(
    endpoint="minio:9000",
    access_key="...",
    secret_key="...",
    secure=False,
    region="us-east-1",
    presigned_expire_seconds=300,
)
storage = ObjectStorage(config)

data = storage.get_object(bucket="private-media", object_key="key")
storage.put_object(
    bucket="public-media",
    object_key="key/variants/thumb_webp/thumb.webp",
    data=variant_bytes,
    content_type="image/webp",
)

Methods: stat_object, remove_object, get_object_head, get_object, put_object, set_object_content_type, copy_object, post_upload_url, presigned_post_object, presigned_get_object.

Presigned-URL expiry defaults to config.presigned_expire_seconds and can be overridden per call via expires_seconds.

Job contracts — media_sdk_m8.contracts

Self-contained Pydantic v2 models that form the producer↔consumer contract. The service builds and enqueues them; the worker deserializes and acts on them.

• ScanJobPayload — { object_id, bucket, object_key, owner_user_id }
• VariantSpec — { variant_name, output_options, target_bucket, target_key }; output_options is the imgtools-shaped dict (one format + name) built by the service, so the worker needs no preset or key knowledge.
• VariantJobPayload — { job_id, media_object_id, source_bucket, source_object_key, specs }
