Try not to break it. */ - -#define DV1394_API_VERSION 0x20011127 - -/* ******************** - ** ** - ** 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 { - int i; - for (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 available (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). - -*/ - - -/* maximum number of frames in the ringbuffer */ -#define DV1394_MAX_FRAMES 32 - -/* number of *full* isochronous packets per DV frame */ -#define DV1394_NTSC_PACKETS_PER_FRAME 250 -#define DV1394_PAL_PACKETS_PER_FRAME 300 - -/* size of one frame's worth of DV data, in bytes */ -#define DV1394_NTSC_FRAME_SIZE (480 * DV1394_NTSC_PACKETS_PER_FRAME) -#define DV1394_PAL_FRAME_SIZE (480 * DV1394_PAL_PACKETS_PER_FRAME) - - -/* ioctl() commands */ - -enum { - /* I don't like using 0 as a valid ioctl() */ - DV1394_INVALID = 0, - - - /* get the driver ready to transmit video. - pass a struct dv1394_init* as the parameter (see below), - or NULL to get default parameters */ - DV1394_INIT, - - - /* stop transmitting video and free the ringbuffer */ - DV1394_SHUTDOWN, - - - /* submit N new frames to be transmitted, where - the index of the first new frame is first_clear_buffer, - and the index of the last new frame is - (first_clear_buffer + N) % n_frames */ - DV1394_SUBMIT_FRAMES, - - - /* block until N buffers are clear (pass N as the parameter) - Because we re-transmit the last frame on underrun, there - will at most be n_frames - 1 clear frames at any time */ - DV1394_WAIT_FRAMES, - - /* capture new frames that have been received, where - the index of the first new frame is first_clear_buffer, - and the index of the last new frame is - (first_clear_buffer + N) % n_frames */ - DV1394_RECEIVE_FRAMES, - - - DV1394_START_RECEIVE, - - - /* pass a struct dv1394_status* as the parameter (see below) */ - DV1394_GET_STATUS, -}; - - - -enum pal_or_ntsc { - DV1394_NTSC = 0, - DV1394_PAL -}; - - - - -/* this is the argument to DV1394_INIT */ -struct dv1394_init { - /* DV1394_API_VERSION */ - unsigned int api_version; - - /* isochronous transmission channel to use */ - unsigned int channel; - - /* number of frames in the ringbuffer.

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.
