+/* ********************
+ ** **
+ ** 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.

+
+/*
+ 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.
