title: MobileVLCKit-prod shows black screen (Xcode 9)
body: <p>When compiling MobileVLCKit-prod (version 2.7.9) and Xcode 9 the player plays sound but doesn't plays the video.</p>
  
  <p>I think is SDK or Xcode related since I already have my app in the AppStore and it works perfectly with MobileVLCKit-prod (version 2.7.9) but it was compiled with Xcode 8.</p>
  
  <p>If I try to compile with MobileVLCKit-unstable (version 3.0.0a42) it works with Xcode 9.</p>
  
  <p>Anyway I feel the MobileVLCKit-unstable version is too much "unstable" compared to MobileVLCKit-prod (version 2.7.9).
  Someone experienced a way to use MobileVLCKit-prod (version 2.7.9) with Xcode 9?</p>
  
  <p>thanks in advance!</p>
