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.

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. + + */ + +struct dv1394_status { + /* this embedded init struct returns the current dv1394 + parameters in use */ + struct dv1394_init init; + + /* the ringbuffer frame that is currently being + displayed.
