title: Why desktop chrome only supports Widevine CDM security level L3?
body: <p>I am curious why desktop Chrome only supports L3 CDM, while android Chrome and ChromeOS can support L1 CDM.</p>
  
  <p><strong>Is there any possible reason for that??</strong></p>
  
  <p>Just to roughly guess, two possible reason could be to support Linux platform and for wide usage of Chrome?</p>
  
  <p>1) I read someone saying that to use L1 CDM 'secure media path' has to be implemented in graphic pipe line and Linux doesn't have it implemented.</p>
  
  <p>2) Desktop Chrome doesn't wanna be restricted by H/W requirements?</p>
