We have a responsive web app (html5 + AngularJS) w/ an API (Web API, c#). Both the web app and api are hosted on Microsoft Azure and media files (images, files, videos, ...) are stored in Azure Blob Storage
The use case is the following:
1) User A uploads a video via the API
2) The API needs to fix the rotation of the video to avoid videos recorded in portrait mode to show stretched in full screen on Mobile Chrome in Android (Vertical Video Syndrome https://www.youtube.com/watch?v=Bt9zSfinwFA)
3) If User B has rights to access the video (not all users of the platform have), he should be able to stream the video
I was looking to use Azure Media Services (https://azure.microsoft.com/en-us/blog/advanced-encoding-features-in-azure-media-encoder/) to rotate the video and therefore implement step 2.
What would be the best way to implement 3, e.g, protect the content in order to ensure that only specific users of the platform have access to the video?
Thank you.
Answering your question at the end: 'What would be the best way to implement 3, e.g, protected the content in order to ensure that only specific users of the platform have access to the video?':
You have different options depending on the level of protection you require:
The DRM approach is the most secure as it also protects you against the user copying or saving and redistributing the video.
As you are using Azure you might want to look at Azure's content protection - if you are using a different video hosting service they will usually have similar guidelines:
