Extra buffer metadata describing an image region of interest

Fields

GstVideoRegionOfInterestMeta _cInstance

Methods

void * _cPtr()

gst.meta.Meta meta() @propertyGet `meta` field. Returns: parent #GstMeta

glib.types.Quark roiType() @propertyGet `roiType` field. Returns: GQuark describing the semantic of the Roi (f.i. a face, a pedestrian)

void roiType(glib.types.Quark propval) @propertySet `roiType` field. Params: propval = GQuark describing the semantic of the Roi (f.i. a face, a pedestrian)

int id() @propertyGet `id` field. Returns: identifier of this particular ROI

void id(int propval) @propertySet `id` field. Params: propval = identifier of this particular ROI

int parentId() @propertyGet `parentId` field. Returns: identifier of its parent ROI, used f.i. for ROI hierarchisation.

void parentId(int propval) @propertySet `parentId` field. Params: propval = identifier of its parent ROI, used f.i. for ROI hierarchisation.

uint x() @propertyGet `x` field. Returns: x component of upper-left corner

void x(uint propval) @propertySet `x` field. Params: propval = x component of upper-left corner

uint y() @propertyGet `y` field. Returns: y component of upper-left corner

void y(uint propval) @propertySet `y` field. Params: propval = y component of upper-left corner

uint w() @propertyGet `w` field. Returns: bounding box width

void w(uint propval) @propertySet `w` field. Params: propval = bounding box width

uint h() @propertyGet `h` field. Returns: bounding box height

void h(uint propval) @propertySet `h` field. Params: propval = bounding box height

void addParam(gst.structure.Structure s)Attach element-specific parameters to meta meant to be used by downstream elements which may handle this ROI. The name of `s` is used to identify the element these parameters are meant for.

gst.structure.Structure getParam(string name)Retrieve the parameter for meta having name as structure name, or null if there is none.

gst.meta_info.MetaInfo getInfo()
