title: YouTube v2 API redirector.c.youtube.com
body: <p>I have a LG BluRay player which only supports the YouTube v2 API.</p>
  
  <p>Since april Google deprecated the v1 and v2 API and now it can't stream from YouTube anymore.</p>
  
  <p>I'm writing an adapter which answers like the v2 API and does v3 requests. When I've polished everything I'm planning to open source it.</p>
  
  <p>So far everything seems to work but I'd like to know how my BluRay player constructs the following request:</p>

  <p>None of these identifiers are send from my script and I'm sure the bluray player didn't contact youtube.</p>
  
  <p>The Google video identifier for this movie is UKY3scPIMd8 which isn't in the identifiers.</p>
  
  <p>Does someone have access to the documentation for redirector.c.youtube.com/videoplayback?</p>
  
  <p>I'd like to know how I can translate the above URL to a youtube identifier like UKY3scPIMd8 (<a href="https://www.youtube.com/watch?v=UKY3scPIMd8" rel="nofollow">https://www.youtube.com/watch?v=UKY3scPIMd8</a>)</p>
