Azure Media for Node.js
Azure's Media REST API provides a way to store, encode, and deliver media (video and images). This library makes using the API easier.
var AzureMedia = require('azure-media');
var myconfig = require('./myconfig');
var api = new AzureMedia(myconfig); // {client_id: 'your azure media id', client_secret: 'your azure media secret'}
api.init(function (err) {
// do your work here or after this callback
});
Install
npm install azure-media
Using Microsoft's Documentation
All of the data structures and endpoints used in this library are documented in Azure Media Service REST API Reference.
Each subsection is modeled based on its "Entity Properties" section (eg. Asset Entity Properties).
Each model usable at API.rest.[lowercase model name]
with create, get, update, list methods.
REST Endpoints
All REST endpoints are in the initialized api lib at api.rest.someendpoint (eg. api.rest.asset
)
"data" is a JavaScript object for the appropriate endpoint model documented in the Properties section of each model in Azure Media Service REST API Reference.
Callbacks generally return an object, called a model. It uses VeryModel. VeryModel instances behave like normal objects. If you want a simpler object, call .toObject()
and use the returned value.
Each endpoint will have some of the following methods:
update
Signature: update(id, data, callback)
Callback: function (err, model)
create
Signature: create(data, callback)
Callback: function(err, model)
Example:
api.rest.asset.create({Name: 'Some Asset'}, function (err, asset) {
if (err) {
console.log(err);
} else {
console.log("Created asset: " + asset.Id);
}
});
delete
Signature: delete(id, callback)
Callback: function(err)
get
Signature: get(id, callback)
Callback: function(err, model)
list
Signature: list(callback, query)
Callback: function(err, model)
The query
parameter is a JavaScript object of the query parameters documented in OData Query String Options (eg: {'$filter': "Name eq 'Bill'"}
)
###accesspolicy
AccessPolicys should be reused, rather than just creating a new one for every use. So rather than create, or trying to manage this yourself, use
Signature: findOrCreate(durationInMinutes, permissions, callback)
Callback: function (err, accesspolicy_model)
###assetfileindex ###ingestmanifestasset ###job
Signature: cancel(id, callback)
Callback: function (err)
###locator ###notificationendpoint ###tasktemplate ###asset
###contentkey ###ingestmanifest ###ingestmanifestfile ###jobtemplate ###mediaprocessor ###task
Models
Most callbacks return a VeryModel instance. These are based on Microsoft's documentation and are implemented in /models/
Some models have extra ORM-like methods, allowing you to interact with the model itself which will work with the Azure REST API behind the scenes.

Workflow Methods
###uploadStream
api.uploadStream('somefile.mp4', fs.createReadStream('/some/file.mp4'), fs.statSync('/some/file.mp4').size, function (err, path, result) {
}, function (err, path) {
if(!err) {
console.log("done uploading");
}
});
downloadStream
api.downloadStream(assetId, 'video/mp4', fs.createWriteStream('/some/download/path.mp4', function (err) {
});
getDownloadURL
api.getDownloadURL(assetId, 'video/mp4', fs.createWriteStream('/some/download/path.mp4', function (err, url) {
});
encodeVideo
api.encodeVideo(assetId, 'H264 Broadband SD 4x3', function (err, job)) {
});
