Uploading From Cloud Storage

There are three primary ways to provide video files to NomadicML:

1. Public URLs or Local Files: The simplest method for getting started. See the Quickstart guide for examples.
2. Direct Cloud Integration: Grant our backend read-only access to your cloud storage bucket. This is the recommended approach for automated, continuous data ingestion.
3. Signed URLs: Generate temporary, secure URLs for individual private files. This is ideal for one-off uploads from a secure environment.

This page covers the two cloud-native methods in detail below.

​

Direct Cloud Integration

To avoid exchanging keys, we offer direct integration with your cloud storage. This approach is ideal for continuous data ingestion pipelines. We support secure, read-only access for the following providers:

This method avoids exchanging secret keys and gives you full control to manage access from your cloud console. Please contact our support team to configure a direct integration.

​

Signed URLs

If your videos are stored privately in Amazon S3 or Google Cloud Storage, you can provide NomadicML with a pre-signed URL. The SDK will download the file directly.

​

AWS S3 Example

import boto3

s3_client = boto3.client('s3')
url = s3_client.generate_presigned_url(
    'get_object',
    Params={'Bucket': 'my-bucket', 'Key': 'videos/my_video.mp4'},
    ExpiresIn=3600  # URL valid for 1 hour
)

response = client.upload(url)
response = client.analyze(response['video_id'])

​

Google Cloud Storage Example

from google.cloud import storage

client_gcs = storage.Client()
blob = client_gcs.bucket('my-bucket').blob('videos/my_video.mp4')
url = blob.generate_signed_url(expiration=3600)

response = client.upload(url)
response = client.analyze(response['video_id'])

​

Azure Blob Storage Example

In Azure, you can generate a Shared Access Signature (SAS) token to create a temporary, secure URL.

from datetime import datetime, timedelta
from azure.storage.blob import BlobServiceClient, generate_blob_sas, BlobSasPermissions

# Get this from the Azure Portal
connection_string = "<YOUR_CONNECTION_STRING>"
blob_service_client = BlobServiceClient.from_connection_string(connection_string)

container_name = "my-container"
blob_name = "videos/my_video.mp4"

sas_token = generate_blob_sas(
    account_name=blob_service_client.account_name,
    container_name=container_name,
    blob_name=blob_name,
    account_key=blob_service_client.credential.account_key,
    permission=BlobSasPermissions(read=True),
    expiry=datetime.utcnow() + timedelta(hours=1)
)

url = f"https://{blob_service_client.account_name}.blob.core.windows.net/{container_name}/{blob_name}?{sas_token}"

response = client.upload(url)
response = client.analyze(response['video_id'])

If you have many URLs you can pass them as a list or organize them in folders. See SDK Usage Examples for full workflows.
