static bool	BuildGeometryFrameRef (const VideoPicture &picture, const CDVDStreamInfo &hint, KODI::VIDEO::GEOMETRY::FrameRef &frame)
	Describe a decoded picture to the detector. Reads the layout from the pixel format descriptor, so an unfamiliar one is described correctly or refused. Fails for a picture whose buffer exposes no planes.
static bool	BuildGeometryFrameRef (const KODI::VIDEO::GEOMETRY::ReducedFrame &reduction, const VideoPicture &picture, const CDVDStreamInfo &hint, KODI::VIDEO::GEOMETRY::FrameRef &frame)
	Point a FrameRef at a reduced copy instead of the picture itself. What such a frame detects is in the reduction's coordinates, and scaling it back is the caller's job.

Detailed Description

Decodes a file at several points and describes each picture to the detector.

Member Function Documentation

BuildGeometryFrameRef() [1/2]

bool CVideoFileGeometry::BuildGeometryFrameRef ( const KODI::VIDEO::GEOMETRY::ReducedFrame & reduction, const VideoPicture & picture, const CDVDStreamInfo & hint, KODI::VIDEO::GEOMETRY::FrameRef & frame )

static

Point a FrameRef at a reduced copy instead of the picture itself. What such a frame detects is in the reduction's coordinates, and scaling it back is the caller's job.

BuildGeometryFrameRef() [2/2]

bool CVideoFileGeometry::BuildGeometryFrameRef ( const VideoPicture & picture, const CDVDStreamInfo & hint, KODI::VIDEO::GEOMETRY::FrameRef & frame )

static

Describe a decoded picture to the detector. Reads the layout from the pixel format descriptor, so an unfamiliar one is described correctly or refused. Fails for a picture whose buffer exposes no planes.

CanMeasure()

bool CVideoFileGeometry::CanMeasure ( const CFileItem & fileItem )

static

Whether ExtractContentGeometry() may open the item.

ExtractContentGeometry()

SampledGeometry CVideoFileGeometry::ExtractContentGeometry ( const CFileItem & fileItem, const KODI::VIDEO::GEOMETRY::SamplingParams & sampling = {}, const KODI::VIDEO::GEOMETRY::CombinerParams & combining = {}, const std::function< bool()> & cancelled = {} )

static

Sample a file at several points and work out its picture rectangle. Decodes in software with film grain synthesis off. cancelled is asked between positions, and a scan reporting itself cancelled must not be stored.
