1. Automated video preprocessing for machine learning.

    Python

    To set up automated video preprocessing for machine learning, you'll want to utilize cloud services that can handle video ingestion, processing, and potentially trigger machine learning workflows. Azure offers services like Azure Video Analyzer and Azure Media Services that can assist with these tasks.

    Azure Video Analyzer is particularly well suited for building video analytics solutions, including preprocessing videos for machine learning. Video Analyzer encompasses video ingestion, encoding, and indexing services. Additionally, it includes AI capabilities for video content analysis that could be used to preprocess and filter content before it's fed into a machine learning model.

    Here's a Python program that utilizes Pulumi with the azure-native package to create an Azure Video Analyzer pipeline that automatically pre-processes video data:

    import pulumi import pulumi_azure_native.videoanalyzer as videoanalyzer import pulumi_azure_native.resources as resources # Setup a new resource group resource_group = resources.ResourceGroup('video-preprocessing-rg') # Create an Azure Video Analyzer account video_analyzer_account = videoanalyzer.Account('videoAnalyzerAccount', resource_group_name=resource_group.name, location=resource_group.location, # Additional properties can be set according to the specific requirements ) # ... Add resources and services like pipeline, video input, roles for access control, etc... # Define an access policy for the Video Analyzer access_policy = videoanalyzer.AccessPolicy('accessPolicy', resource_group_name=resource_group.name, account_name=video_analyzer_account.name, role=videoanalyzer.Role.CONTRIBUTOR, # Additional configurations for the policy can be specified here ) # Now, you could create an automation that triggers before sending a video for machine learning # this could include custom code to invoke Azure functions or Azure logic apps to preprocess # the video before sending for the machine learning task. # pulumi.export('videoAnalyzerEndpoint', video_analyzer_account.properties.videoAnalyzerAccountNameEndpoint) pulumi.export('accessPolicyId', access_policy.id)

    This program sets up a basic infrastructure for a video preprocessing setup in Azure, which includes:

    1. Resource Group: A logical container for Azure resources.
    2. Video Analyzer Account: The central resource for Video Analyzer operations. Video files will be ingested here and can be processed using various Video Analyzer features.
    3. Access Policy: Defines who can access the Video Analyzer resources and what permissions they have.

    Please note that the actual preprocessing logic is not detailed here – you would need to provide that, which could be a script or an Azure Function that is triggered when a new video is uploaded. The preprocessing steps would vary based on what kind of machine learning model you'll be feeding the data into.

    Once preprocessed, you could store the video data in Azure Blob Storage or pass it directly to an Azure Machine Learning service for model training and inference.

    Remember to replace placeholders like # Additional properties can be set according to the specific requirements with actual values and configurations that suit your need.

    This program assumes that Azure's configuration for authentication and region selection is already handled outside of the code shown. Also, this program doesn't include error handling and should be adapted to handle various operational cases as may be required in a production environment.
