 // build of Chromium, so the (potential) linking with AVFoundation has to happen
 // in runtime. For this to be clean, an AVFoundationGlue class is defined to try
 // and load these AVFoundation system libraries. If it succeeds, subsequent
 // clients can use AVFoundation via the rest of the classes declared in this
