double bitrate
void outputWhat(std::ostream &o) const
Contains a Lambda-modifier and bitrate for only a single index.
std::vector< double > guessLambdaModifiers(double initialAdjustmentParameter, const std::vector< double > &targetBitrateVector, const std::list< MetaLogEntry< std::vector< double > > > &metaLogEntryList)
Thrown if there is an error parsing the initial adjustment parameter.
double polateLambdaModifier(double targetBitrate, const Point &point1, const Point &point2)
Thrown if there is an error parsing the targets.
TLambdaModifier lambdaModifiers
std::vector< double > bitrateVector
Thrown if there is an error parsing the meta-log.
Full meta-log entry.
double lambdaModifier
Thrown if there is a mismatch in the vector sizes or the Lambda-modifier indexes. ...

void outputWhat(std::ostream &o) const
This class serves the same purpose as std::runtime_error, but it can be more convenient to use...
