Sure, it's a sweeping generalization, but a surprisingly accurate one. It's pretty crazy. There are probably a hundred or even two hundred different ways you can compare the two companies, and Google is superior in all but three of them, if I recall correctly. I actually did a spreadsheet at one point but Legal wouldn't let me show it to anyone, even though recruiting loved it.

How to download m3u8 and ts video movie streams.

m3u8 Downloading

  1. Open Chrome Developer tools and click the Network tab.
  2. Navigate to the page with the video and get it to start playing.
  3. Filter the list of files to "m3u8".
  4. Find master.m3u8 or index.m3u8 and click on it.
  5. Save the file to disk and look inside it.
  6. If the file contains a single m3u8 master url, copy that one instead.
  7. Run the program m3u8x.
  8. Paste the same m3u8 url in both textboxes (URL and Quality URL) and click "Headers" and set the referral url and user-agent from the request as found in Chrome.
