   7 .SH NAME
   8 dcam1394 \- 1394-based digital camera (IIDC) driver
   9 .SH SYNOPSIS
  10 .LP
  11 .nf
  12 \fB#include <sys/dcam/dcam1394_io.h>\fR
  13 .fi
  14 
  15 .SH DESCRIPTION
  16 .sp
  17 .LP
  18 The \fBdcam1394\fR driver supports devices implementing the \fI1394 Trade
  19 Association Digital Camera Specification\fR (also referred to as the IIDC
  20 specification).  Only a subset of the specification is supported.
  21 .SH READING DATA
  22 .sp
  23 .LP
  24 Isochronous data is read from the driver frame-by-frame and is maintained
  25 within the driver in a ring buffer.
  26 .sp
  27 .LP
  28 Video frames are read from the isochronous input device using \fBread\fR(2).
  29 .sp
  30 .LP
  31 The \fBdcam1394_frame_t\fR structure describes the frame layout and is defined
  32 as follows:
  33 .sp
  34 .in +2
  35 .nf
  36      struct {
  37           unsigned int vid_mode;
  38           unsigned int seq_num;
  39           hrtime_t     timestamp;
  40           unsigned char *buff;
  41      };
  42 .fi
  43 .in -2
  44 
  45 .sp
  46 .LP
  47 The size to allocate for the structure is determined by the video mode for
  48 which the camera is configured. Possible values for the vid_mode field are
  49 listed under DCAM1394_PARAM_VID_MODE below.
  50 .SH IOCTL REQUESTS
  51 .sp

  78          unsigned int val;
  79     };
  80 .fi
  81 .in -2
  82 
  83 The offs field should be set to the offset of the register from which to read.
  84 Register offset values are defined in the \fI1394 Trade Association Digital
  85 Camera Specification\fR.
