You are right! I messed up my Method 2, the correct code should be:
  (defun music-play-directory (dir)
    (interactive
     (let ((promt "Play directory: ")
           (mustmatch t))
       (list (emms-read-directory-name promt
                                       emms-source-file-default-directory
                                       emms-source-file-default-directory
                                       mustmatch))))
    (let ((emms-player-vlc-parameters (cons "--no-video"
                                            emms-player-vlc-parameters)))
      (emms-play-directory dir)))

which has the problem that it only works for the 1st video being played
but not for the rest of the video in the directory.
