-   **                **
-   **   DV1394 API   **
-   **                **
-   ********************
-
-   There are two methods of operating the DV1394 DV output device.
-
-   1)
-
-   The simplest is an interface based on write(): simply write
-   full DV frames of data to the device, and they will be transmitted
-   as quickly as possible. The FD may be set for non-blocking I/O,
-   in which case you can use select() or poll() to wait for output
-   buffer space.
-
-   To set the DV output parameters (e.g. whether you want NTSC or PAL
-   video), use the DV1394_INIT ioctl, passing in the parameters you
-   want in a struct dv1394_init.
-
-   Example 1:
-         To play a raw .DV file:   cat foo.DV > /dev/dv1394
-         (cat will use write() internally)
-
-   Example 2:
-           static struct dv1394_init init = {
-              0x63,        (broadcast channel)
-              4,           (four-frame ringbuffer)
-              DV1394_NTSC, (send NTSC video)
-              0, 0         (default empty packet rate)
-           }
-
-           ioctl(fd, DV1394_INIT, &init);
-
-           while(1) {
-                  read( <a raw DV file>, buf, DV1394_NTSC_FRAME_SIZE );
-                  write( <the dv1394 FD>, buf, DV1394_NTSC_FRAME_SIZE );
-           }
-
-   2)
-
-   For more control over buffering, and to avoid unnecessary copies
-   of the DV data, you can use the more sophisticated the mmap() interface.
-   First, call the DV1394_INIT ioctl to specify your parameters,
-   including the number of frames in the ringbuffer. Then, calling mmap()
-   on the dv1394 device will give you direct access to the ringbuffer
-   from which the DV card reads your frame data.
-
-   The ringbuffer is simply one large, contiguous region of memory
-   containing two or more frames of packed DV data. Each frame of DV data
-   is 120000 bytes (NTSC) or 144000 bytes (PAL).
-
-   Fill one or more frames in the ringbuffer, then use the DV1394_SUBMIT_FRAMES
-   ioctl to begin I/O. You can use either the DV1394_WAIT_FRAMES ioctl
-   or select()/poll() to wait until the frames are transmitted. Next, you'll
-   need to call the DV1394_GET_STATUS ioctl to determine which ringbuffer
-   frames are clear (ready to be filled with new DV data). Finally, use
-   DV1394_SUBMIT_FRAMES again to send the new data to the DV output.
-
-
-   Example: here is what a four-frame ringbuffer might look like
-            during DV transmission:
-
-
-         frame 0   frame 1   frame 2   frame 3
-
-        *--------------------------------------*
-        | CLEAR   | DV data | DV data | CLEAR  |
-        *--------------------------------------*
-                   <ACTIVE>
-
-        transmission goes in this direction --->>>
-
-
-   The DV hardware is currently transmitting the data in frame 1.
-   Once frame 1 is finished, it will automatically transmit frame 2.
-   (if frame 2 finishes before frame 3 is submitted, the device
-   will continue to transmit frame 2, and will increase the dropped_frames
-   counter each time it repeats the transmission).
-
-
-   If you called DV1394_GET_STATUS at this instant, you would
-   receive the following values:
-
-                  n_frames          = 4
-                  active_frame      = 1
-                  first_clear_frame = 3
-                  n_clear_frames    = 2
-
-   At this point, you should write new DV data into frame 3 and optionally
-   frame 0. Then call DV1394_SUBMIT_FRAMES to inform the device that
-   it may transmit the new frames.
-
-   ERROR HANDLING
-
-   An error (buffer underflow/overflow or a break in the DV stream due
-   to a 1394 bus reset) can be detected by checking the dropped_frames
-   field of struct dv1394_status (obtained through the
-   DV1394_GET_STATUS ioctl).
-
-   The best way to recover from such an error is to re-initialize
-   dv1394, either by using the DV1394_INIT ioctl call, or closing the
-   file descriptor and opening it again. (note that you must unmap all
-   ringbuffer mappings when closing the file descriptor, or else
-   dv1394 will still be considered 'in use').
-
-   MAIN LOOP
-
-   For maximum efficiency and robustness against bus errors, you are
-   advised to model the main loop of your application after the
-   following pseudo-code example:
-
-   (checks of system call return values omitted for brevity; always
-   check return values in your code!)
-
-   while( frames left ) {
-
-    struct pollfd *pfd = ...;
-
-    pfd->fd = dv1394_fd;
-    pfd->revents = 0;
-    pfd->events = POLLOUT | POLLIN; (OUT for transmit, IN for receive)
-
-    (add other sources of I/O here)
-
-    poll(pfd, 1, -1); (or select(); add a timeout if you want)
-
-    if(pfd->revents) {
-         struct dv1394_status status;
-
-         ioctl(dv1394_fd, DV1394_GET_STATUS, &status);
-
-         if(status.dropped_frames > 0) {
-              reset_dv1394();
-         } else {
-              for(int i = 0; i < status.n_clear_frames; i++) {
-                  copy_DV_frame();
-              }
-         }
-    }
-   }
-
-   where copy_DV_frame() reads or writes on the dv1394 file descriptor
-   (read/write mode) or copies data to/from the mmap ringbuffer and
-   then calls ioctl(DV1394_SUBMIT_FRAMES) to notify dv1394 that new
-   frames are availble (mmap mode).
-
-   reset_dv1394() is called in the event of a buffer
-   underflow/overflow or a halt in the DV stream (e.g. due to a 1394
-   bus reset). To guarantee recovery from the error, this function
-   should close the dv1394 file descriptor (and munmap() all
-   ringbuffer mappings, if you are using them), then re-open the
-   dv1394 device (and re-map the ringbuffer).

-
-/* Q: What are cip_n and cip_d? */
-
-/*
-  A: DV video streams do not utilize 100% of the potential bandwidth offered
-  by IEEE 1394 (FireWire). To achieve the correct rate of data transmission,
-  DV devices must periodically insert empty packets into the 1394 data stream.
-  Typically there is one empty packet per 14-16 data-carrying packets.
-
-  Some DV devices will accept a wide range of empty packet rates, while others
-  require a precise rate. If the dv1394 driver produces empty packets at
-  a rate that your device does not accept, you may see ugly patterns on the
-  DV output, or even no output at all.
-
-  The default empty packet insertion rate seems to work for many people; if
-  your DV output is stable, you can simply ignore this discussion. However,
-  we have exposed the empty packet rate as a parameter to support devices that
-  do not work with the default rate.
-
-  The decision to insert an empty packet is made with a numerator/denominator
-  algorithm. Empty packets are produced at an average rate of CIP_N / CIP_D.
-  You can alter the empty packet rate by passing non-zero values for cip_n
-  and cip_d to the INIT ioctl.
