Member Function Documentation

guint Gst::DiscovererVideoInfo::get_bitrate

(

)

const

Returns

The average or nominal bitrate of the video stream in bits/second.

guint Gst::DiscovererVideoInfo::get_depth

(

)

const

Returns

The depth in bits of the video stream.

guint Gst::DiscovererVideoInfo::get_framerate_denom

(

)

const

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.

guint Gst::DiscovererVideoInfo::get_par_denom

(

)

const

Returns

The Pixel Aspect Ratio (PAR) of the video stream (denominator).

guint Gst::DiscovererVideoInfo::get_par_num

(

)

const

Returns

The Pixel Aspect Ratio (PAR) of the video stream (numerator).

guint Gst::DiscovererVideoInfo::get_width

(

)

const

Returns

The width of the video stream in pixels.

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  )

related

A Glib::wrap() method for this object.

Parameters

object	The C instance.
take_copy	False if the result should take ownership of the C instance. True if it should take a new copy or ref.

Returns

A C++ instance that wraps this C instance.
