harmonic_external_asset_ism_ismc_generation_tool is a command line tool to generate the ISM/ISMC manifest for the .mp4 files stored in Azure containers.

HowTo run

python3 main.py -connection_string=<Azure storage account's connection string> -container_name=<Azure container name>

or

python3 main.py

in case if the configuration file azure_config.json has been filled (the configuration file shall be situated in the same folder as the main.py file).

azure_config.json

azure_config.json - configuration file may contain the following fields: connection_string, account_name, account_key, container_name:

{
  "connection_string": "DefaultEndpointsProtocol=https;AccountName=flametestextassetstorage;AccountKey=<key>;EndpointSuffix=core.windows.net",
  "account_name": "flametestextassetstorage",
  "account_key": "<key>",
  "container_name": "test2"
}

It's possible to set the connection_string fileld or account_name and account_key . If only the account_name and account_key fields are specified, the connection string is formed from them. If all fields are set, only the connection_string field value is used. In this case the account_name and account_key fields are ignored.

Azure connection string can be found in Azure Portal → Storage container → Access keys → Connection string
