Need to Extract and Calculate the n-Parameter from YouTube's base.js for Fast, Throttle-Free Downloads (Player Version c9dd45ed) #198

To ensure fast, non-throttled download links from YouTube, the n-parameter needs to be extracted and calculated from YouTube's base.js. In the latest player version c9dd45ed, the n-parameter code appears in the following snippet:

a.D&&(b="nn"[+a.D],WL(a),c=a.j[b]||null)&&(c=SDa[0](c),a.set(b,c),SDa.length||Wma(""))}};

The task requires:

  1. Extracting the function name that this snippet belongs to.
  2. Extracting the entire function body from the base.js file.
  3. Calculating the n-parameter value by running this extracted function to derive the correct signature for downloading videos without throttling. Currently, without handling the n-parameter correctly, download speeds are significantly throttled. Addressing this will ensure faster download links.
