Returns
The framerate of the video stream (denominator).
guint Gst::DiscovererVideoInfo::get_framerate_num ( ) const
Returns
The framerate of the video stream (numerator).
guint Gst::DiscovererVideoInfo::get_height ( ) const
Returns
The height of the video stream in pixels.
guint Gst::DiscovererVideoInfo::get_max_bitrate ( ) const
Returns
The maximum bitrate of the video stream in bits/second.

GstDiscovererVideoInfo* Gst::DiscovererVideoInfo::gobj ( )

Provides access to the underlying C instance.

const GstDiscovererVideoInfo* Gst::DiscovererVideoInfo::gobj ( ) const

Provides access to the underlying C instance.

GstDiscovererVideoInfo* Gst::DiscovererVideoInfo::gobj_copy ( ) const

Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.

bool Gst::DiscovererVideoInfo::is_image ( ) const
Returns
#true if the video stream corresponds to an image (i.e. only contains one frame).
bool Gst::DiscovererVideoInfo::is_interlaced ( ) const
Returns
true if the stream is interlaced, else false.
void Gst::DiscovererVideoInfo::operator delete ( void *  ,
std::size_t   
)
protected
void Gst::DiscovererVideoInfo::reference ( ) const

Increment the reference count for this object.

You should never need to do this manually - use the object via a RefPtr instead.

void Gst::DiscovererVideoInfo::unreference ( ) const

Decrement the reference count for this object.

You should never need to do this manually - use the object via a RefPtr instead.

Friends And Related Function Documentation

Glib::RefPtr< Gst::DiscovererVideoInfo > wrap ( GstDiscovererVideoInfo *  object,
bool  take_copy = false
