Detailed Description

Wrapper for the ImageTransport class: does not respond to pings by default ( must do this manually).

This class is kept in the utils library to keep opencv out of the basic requirements.

Constructor & Destructor Documentation

ImageSource

(

const std::string &

streamname

)

[inline, explicit]

Default non-mcp constructor.

Definition at line 23 of file ImageSource.H.

References ImageTransport::data, ImageTransportDataStruct::image, ImageTransportDataStruct::imagesize, ImageTransport::setAutoPing(), and Capability::setAutoTimestamp().

ImageSource	(	const ConnectionStrategy &	strategy,
		const std::string &	gblName
	)			[inline]

Auto-wiring constructor.

Submits a request to MCP for a stream to connect to, based on global name. ConnectionStrategy should be auto for now.

Definition at line 36 of file ImageSource.H.

References ImageTransport::data, ImageTransportDataStruct::image, ImageTransportDataStruct::imagesize, ImageTransport::setAutoPing(), and Capability::setAutoTimestamp().

ImageSource	(	const std::string &	streamname,
		const std::string &	gblName
	)			[inline]

Like the standard constructor, but explicitly sets the global name.

Use this when starting multiple instances of the same binary, so that each instance can be assigned a separate name.
