I have a sink need implement
GST_CAPS_FEATURE_META_GST_VIDEO_OVERLAY_COMPOSITION feature, so I use
gst_buffer_get_video_overlay_composition_meta() to get the composition meta
like following:
GstVideoOverlayCompositionMeta *compmeta =
gst_buffer_get_video_overlay_composition_meta(buffer);
then I need access the data in GstVideoOverlayCompositionMeta.
this was defined in video-overlay-composition.h as following:
struct _GstVideoOverlayCompositionMeta
{
GstMeta meta;
GstVideoOverlayComposition *overlay;
};
then I need access the GstVideoOverlayComposition and rectangles in
GstVideoOverlayComposition. but both of them are defined in
video-overlay-composition.c, How can I use them in my sink source code?
