Store preset settings for codecs

[kibsoft]

Need to create a namespace that will contain functions which return a VideoCodecSettings object. This object must contain settings for a specific preset.

An example:

VideoCodecSettings videoCodecSettings() const
{
    //x264 loseless fast preset
    VideoCodecSettings settings;
    settings.setCoderType(EncoderGlobal::Vlc);
    settings.setFlags(EncoderGlobal::LoopFilter);
    settings.setMotionEstimationComparison(1);
    settings.setPartitions(EncoderGlobal::I4x4 | EncoderGlobal::P8x8);
    settings.setMotionEstimationMethod(EncoderGlobal::Hex);
    settings.setSubpixelMotionEstimationQuality(3);
    settings.setMotionEstimationRange(16);
    settings.setGopSize(250);
    settings.setMinimumKeyframeInterval(25);
    settings.setSceneChangeThreshold(40);
    settings.setIQuantFactor(0.71f);
    settings.setBFrameStrategy(1);
    settings.setQuantizerCurveCompressionFactor(0.6f);
    settings.setMinimumQuantizer(0);
    settings.setMaximumQuantizer(69);
    settings.setMaximumQuantizerDifference(4);
    settings.setDirectMvPredictionMode(EncoderGlobal::SpatialMode);
    settings.setFlags2(EncoderGlobal::FastPSkip);
    settings.setConstantQuantizerMode(0);
    settings.setPFramePredictionAnalysisMethod(EncoderGlobal::NoWpm);

    return settings;
}
