Assets in Azure Media Services v3

In Azure Media Services, an Asset is a core concept. It is where you input media (for example, through upload or live ingest), output media (from a job output), and publish media from (for streaming).

An Asset is mapped to a blob container in the Azure Storage account and the files in the Asset are stored as block blobs in that container. Assets contain information about digital files stored in Azure Storage (including video, audio, images, thumbnail collections, text tracks, and closed caption files).

Media Services supports Blob tiers when the account uses General-purpose v2 (GPv2) storage. With GPv2, you can move files to Cool or Archive storage. Archive storage is suitable for archiving source files when no longer needed (for example, after they've been encoded).

The Archive storage tier is only recommended for very large source files that have already been encoded and the encoding Job output was put in an output blob container. The blobs in the output container that you want to associate with an Asset and use to stream or analyze your content must exist in a Hot or Cool storage tier.

Naming

Assets

Asset's names must be unique. Media Services v3 resource names (for example, Assets, Jobs, Transforms) are subject to Azure Resource Manager naming constraints. For more information, see Naming conventions.

Blobs

The names of files/blobs within an asset must follow both the blob name requirements and the NTFS name requirements. The reason for these requirements is the files can get copied from blob storage to a local NTFS disk for processing.
