Fix media interruption issue when reverse video

I tried to reverse MJPEG format video, but it got media interruption error, and log shown that "This file is invalid and cannot be played.", I found the position of the log, as follow:

source code(qtdemux.c):
------------------------------------------------------------------------------
746  if (G_UNLIKELY (size > QTDEMUX_MAX_ATOM_SIZE)) {
747    if (qtdemux->state != QTDEMUX_STATE_MOVIE && qtdemux->got_moov) {
748      /* we're pulling header but already got most interesting bits,
749       * so never mind the rest (e.g. tags) (that much) */
750      GST_WARNING_OBJECT (qtdemux, "atom has bogus size %" G_GUINT64_FORMAT,
751          size);
752      return GST_FLOW_EOS;
753    } else {
754      GST_ELEMENT_ERROR (qtdemux, STREAM, DEMUX,
755          (_("This file is invalid and cannot be played.")),
756          ("atom has bogus size %" G_GUINT64_FORMAT, size));
757      return GST_FLOW_ERROR;
758    }
759  }
------------------------------------------------------------------------------

  However, if (qtdemux->state == QTDEMUX_STATE_MOVIE && qtdemux->got_moov) is TRUE, could we consider that the file is invalid?
