Functions
static AVScore	QFFmpeg::calculateTargetSwFormatScore (const AVPixFmtDescriptor *sourceSwFormatDesc, AVPixelFormat fmt, const AVPixelFormatSet &prohibitedFormats)
static auto	QFFmpeg::targetSwFormatScoreCalculator (AVPixelFormat sourceFormat, std::reference_wrapper< const AVPixelFormatSet > prohibitedFormats)
static bool	QFFmpeg::isHwFormatAcceptedByCodec (AVPixelFormat pixFormat)
std::optional< AVPixelFormat >	QFFmpeg::findTargetSWFormat (AVPixelFormat sourceSWFormat, const Codec &codec, const HWAccel &accel, const AVPixelFormatSet &prohibitedFormats)
std::optional< AVPixelFormat >	QFFmpeg::findTargetFormat (AVPixelFormat sourceFormat, AVPixelFormat sourceSWFormat, const Codec &codec, const HWAccel *accel, const AVPixelFormatSet &prohibitedFormats)
AVScore	QFFmpeg::findSWFormatScores (const Codec &codec, AVPixelFormat sourceSWFormat)
AVRational	QFFmpeg::adjustFrameRate (QSpan< const AVRational > supportedRates, qreal requestedRate)
	adjustFrameRate get a rational frame rate be requested qreal rate. If the codec supports fixed frame rate (non-null supportedRates), the function selects the most suitable one, otherwise just makes AVRational from qreal.
AVRational	QFFmpeg::adjustFrameTimeBase (QSpan< const AVRational > supportedRates, AVRational frameRate)
	adjustFrameTimeBase gets adjusted timebase by a list of supported frame rates and an already adjusted frame rate.
QSize	QFFmpeg::adjustVideoResolution (const Codec &codec, QSize requestedResolution)
SwsFlags	QFFmpeg::getScaleConversionType (const QSize &sourceSize, const QSize &targetSize)
