BandwidthDetection

Bandwidth Detection with Red5 Pro

This example shows how to easily detect upload and download bandwidth with Red5 Pro prior to beginning a stream.

Example Code

• BaseTest.swift
• BandwidthDetectionTest.swift

How to Check Bandwidth

Checking the bandwidth (download and upload simultaneously) prior to beginning a stream is relatively simple, requiring only a few pieces of setup.

1. One must instantiate an R5BandwidthDetection instance
2. One must then utilize the checkSpeeds method of that instance
3. Doing so requires passing in:
   1. The base url (usually the same as the host you would provide to your R5Configuration)
   2. How long you wish the total bandwidth test to take, in seconds
   3. Callback blocks for the successful and unsuccessful attempts at checking the bandwidth

A simplified example of this would be:

let detection = R5BandwidthDetection()

detection.checkSpeeds("your-host", forSeconds: 2.5, withSuccess: { (response) in
    let responseDict = response! as NSDictionary
    let download = Int32(responseDict.object(forKey: "download") as! Int)
    let upload = Int32(responseDict.object(forKey: "upload") as! Int)

    print("Download speed is \(download)Kbps\nUpload speed is \(upload)Kbps\n")
}) { (error) in
    print("There was an error checking your speeds! \(error?.localizedDescription ?? "Unknown error")")
}

The rest of this example is based on SubscribeTest.swift and ensures that a minimum bandwidth (as defined by the tests.plist file) is met prior to subscribing to the stream.
