Core SDK Examples - Setup Transcoder Provisions


The Setup Ttranscoding Provisions example shows how to send the stream provisioning API request to a Red5 Pro Stream Manager for transcoding node after submitting a stream provision.

The Red5ProStreamManager interface can be used to integrate interactions with Stream Manager into a client application. Its result can be used to set up the ServerDescription structure, which can be used to establish a connection with the server node. The application uses parseProvisions for parsing a JSON file with the targeted provision levels.

Note: this example requires a Red5 Pro autoscale setup with at least one transcoder node. See this document for more information on Red5 Pro transcoder nodes and subscriber ABR support. Keep in mind that

Here is an example of JSON structure with a description of provision levels:

{
    "stream": [
        {
            "level": 1,
            "name": "level_1",
            "properties": {
                "videoBR": 750000,
                "videoFPS": 30,
                "videoHeight": 720,
                "videoWidth": 1280
            }
        },
        {
            "level": 2,
            "name": "level_2",
            "properties": {
                "videoBR": 500000,
                "videoFPS": 30,
                "videoHeight": 480,
                "videoWidth": 640
            }
        },
        {
            "level": 3,
            "name": "level_3",
            "properties": {
                "videoBR": 300000,
                "videoFPS": 15,
                "videoHeight": 240,
                "videoWidth": 320
            }
        }
    ]
}

Note that the stream and level names will be configured depending on corresponding configuration structures, so the same profile description can be used for multiple streams.
