Detailed Description

Internal (non type-safe) class used by DVBuffer2 to do the actual interfacing with the Firewire (IEE 1394) video hardware.

A wrapper for the libdc1394 library, it assumes that the firewire device is on /dev/video1394/0. Use DVBuffer2 if you want 8-bit greyscale or 24-bit colour.

Member Function Documentation

ImageRef CVD::DC::RawDCVideo::size

(

)

The size of the VideoFrames returned by this buffer.

Reimplemented in CVD::DVBuffer2< T >.

VideoFrame<byte>* CVD::DC::RawDCVideo::get_frame

(

)

Returns the next frame from the buffer. This function blocks until a frame is ready.

Reimplemented in CVD::DVBuffer2< T >.

void CVD::DC::RawDCVideo::put_frame

(

VideoFrame< byte > *

f

)

Tell the buffer that you are finished with this frame.

Parameters:

f

The frame that you are finished with.

bool CVD::DC::RawDCVideo::frame_pending

(

)

Is there a frame waiting in the buffer? This function does not block.

Reimplemented in CVD::DVBuffer2< T >.

Set the camera brightness.

Parameters:

b

The requested brightness

unsigned int CVD::DC::RawDCVideo::get_brightness

(

)

Get the camera brightness.

void CVD::DC::RawDCVideo::set_feature_value	(	unsigned int	feature,
		unsigned int	value
	)

Set any DC1394 camera feature value.

Parameters:

	feature	The feature to be set - c.f. dc1394_control.h
	value	Requested feature value

unsigned int CVD::DC::RawDCVideo::get_feature_value

(

unsigned int

feature

)

Get any DC1394 camera feature value.

Parameters:

void CVD::DC::RawDCVideo::auto_on_off	(	unsigned int	feature,
		unsigned int	auto_value
	)

Toggle auto on or off.

Parameters:

	feature	The feature to be toggled
	auto_value	- 0 for auto off, nonzero for auto on

double CVD::DC::RawDCVideo::frame_rate

(

)

Get the camera frame rate.

Reimplemented in CVD::DVBuffer2< T >.

raw1394handle_t& CVD::DC::RawDCVideo::handle
