    • isDataLimitReached

      public boolean isDataLimitReached()
      Description copied from interface: MovieWriter
      Returns true if the limit for media data has been reached. If this limit is reached, no more samples should be added to the movie.

      This limit is imposed by data structures of the movie file which will overflow if more samples are added to the movie.

      FIXME - Maybe replace by getCapacity():long.
