7 7 .SH NAME
8 8 dcam1394 \- 1394-based digital camera (IIDC) driver
9 9 .SH SYNOPSIS

12 11 \fB#include <sys/dcam/dcam1394_io.h>\fR
13 12 .fi

15 14 .SH DESCRIPTION
16 -.sp
17 -.LP
18 15 The \fBdcam1394\fR driver supports devices implementing the \fI1394 Trade
19 16 Association Digital Camera Specification\fR (also referred to as the IIDC
20 17 specification). Only a subset of the specification is supported.
21 18 .SH READING DATA
22 -.sp
23 -.LP
24 19 Isochronous data is read from the driver frame-by-frame and is maintained
25 20 within the driver in a ring buffer.
26 21 .sp
27 22 .LP
28 23 Video frames are read from the isochronous input device using \fBread\fR(2).
29 24 .sp
30 25 .LP
31 26 The \fBdcam1394_frame_t\fR structure describes the frame layout and is defined
32 27 as follows:
33 28 .sp
34 29 .in +2
35 30 .nf
36 31 struct {
37 32 unsigned int vid_mode;
38 33 unsigned int seq_num;
39 34 hrtime_t timestamp;
40 35 unsigned char *buff;

42 37 .fi
43 38 .in -2
44 39
45 40 .sp
46 41 .LP
47 42 The size to allocate for the structure is determined by the video mode for
48 43 which the camera is configured. Possible values for the vid_mode field are
49 44 listed under DCAM1394_PARAM_VID_MODE below.
50 45 .SH IOCTL REQUESTS
51 -.sp
52 -.LP
53 46 The following ioctl requests are supported:

77 70 unsigned int offs;
78 71 unsigned int val;
79 72 };
80 73 .fi
81 74 .in -2
82 75
83 76 The offs field should be set to the offset of the register from which to read.
84 77 Register offset values are defined in the \fI1394 Trade Association Digital
85 78 Camera Specification\fR.
86 79 .sp
87 80 After the operation is completed, the camera register value is put in the
88 81 \fBval\fR field.
