Detailed Description

This class described an OpalTranscoder in terms of a pair of OpalMediaFormat instances, for input and output.

Constructor & Destructor Documentation

OpalMediaFormatPair::OpalMediaFormatPair	(	const OpalMediaFormat &	inputMediaFormat,
		const OpalMediaFormat &	outputMediaFormat
	)

Create a new transcoder implementation.

Parameters

inputMediaFormat	Input media format
outputMediaFormat	Output media format

Member Function Documentation

virtual Comparison OpalMediaFormatPair::Compare ( const PObject &  obj ) const

virtual

Compare the two objects and return their relative rank. This function is usually overridden by descendent classes to yield the ranking according to the semantics of the object.

The default function is to use the CompareObjectMemoryDirect() function to do a byte wise memory comparison of the two objects.

Returns

LessThan, EqualTo or GreaterThan according to the relative rank of the objects.

Parameters

obj	Object to compare against.

const OpalMediaFormat& OpalMediaFormatPair::GetInputFormat ( ) const

inline

Get the names of the input or output formats.

References inputMediaFormat.

const OpalMediaFormat& OpalMediaFormatPair::GetOutputFormat ( ) const

inline

Get the names of the input or output formats.

References outputMediaFormat.

void OpalMediaFormatPair::PrintOn

(

ostream &

strm

)

const

Standard stream print function. The PObject class has a << operator defined that calls this function polymorphically.

Parameters

strm	Stream to output text representation
