 // This standalone binary is a helper for diagnosing seek behavior of the
 // demuxer setup in media/ code.  It answers the question: "if I ask the demuxer
 // to Seek to X ms, where will it actually seek to? (necessitating
 // frame-dropping until the original seek target is reached)".  Sample run:
 //
 // $ ./out/Debug/seek_tester .../LayoutTests/media/content/test.ogv 6300
