QUESTION: Downloading is really slow about youtubekit HOT 4 CLOSED

Basically, you can only download a certain chunk of a file by setting the HTTP headers like this:

var request = URLRequest(url: url)
request.addValue("bytes=\(contentStart)-\(contentEnd)", forHTTPHeaderField: "Range")

Depends a bit on the stream type if this works without throttling or not. For dash audio I personally use this as the previous method is sometimes still throttling (no guarantees that it always works):

var components = URLComponents(url: url, resolvingAgainstBaseURL: false)!
components.queryItems?.append(URLQueryItem(name: "range", value: "\(contentStart)-\(contentEnd)"))
          
var request = URLRequest(url: components.url!)
request.httpMethod = "post"

The way I solved it is by downloading chunks of 2-10 MB in parallel with separate requests and then combining them again. Depending on the type of stream you are downloading, there are different options to request the specific range of bytes.

Thank you!
I am only interested in an audio stream (to transcribe them).
Do you have code samples or links showing how to download in chunks?

Thanks a lot, I managed to make it work using range requests.
Downloading a 30 minutes audio now takes about 5 seconds with chunks of 2MB.
