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
52 .LP
53 The following ioctl requests are supported:

72 \fBdcam1394_reg_io_t\fR structure, which is defined as follows:

74 .in +2
75 .nf
76 struct {
77 unsigned int offs;
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.
86 .sp
87 After the operation is completed, the camera register value is put in the
88 \fBval\fR field.

100 .sp
101 The offs field should be set to the offset of the register from which to read.
102 The register offset values are defined in the \fI1394 Trade Association Digital
