Detailed Description

VideoStream ActionScript object.

A VideoStream provides audio/video frames either embedded into the SWF itself or loaded from the network using an associated NetStream object.

§ add_invalidated_bounds()

void gnash::Video::add_invalidated_bounds	(	InvalidatedRanges &	ranges,
		bool	force
	)

virtual

Add the DisplayObject's invalidated bounds to the given ranges list.

NOTE that this method should include the bounds that it covered the last time clear_invalidated() was called, as those need to be rerendered as well (to clear the region previously occupied by this DisplayObject).

That's why it returns the union of old_invalidated_ranges and the current bounds. The function is also used internally by set_invalidated() to update m_old_invalidated_ranges itself (you may notice some kind of circular reference), but that's no problem since old_invalidated_ranges is NULL during that call.

It is used to determine what area needs to be re-rendered. The coordinates are world coordinates (in TWIPS). Only instances with _invalidated flag set are checked unless force is set.

Reimplemented from gnash::DisplayObject.

§ construct()

void gnash::Video::construct ( as_object * init = nullptr )

virtual

Register this video instance as a live DisplayObject.

§ display()

void gnash::Video::display	(	Renderer &	renderer,
		const Transform &	xform
	)

virtual

Render the DisplayObject.

All DisplayObjects must have a display() function.

§ getBounds()

SWFRect gnash::Video::getBounds ( ) const

virtual

Implements gnash::DisplayObject.

§ height()

int gnash::Video::height ( ) const

Get the height of the video.

The method depends on whether it is an embedded or a live stream. This returns 0 until the height is known, which for FLV streams is only after decoding. The value may possibly vary during playback.

§ markOwnResources()

void gnash::Video::markOwnResources ( ) const

protectedvirtual

Mark video-specific reachable resources.

video-specific reachable resources are:

§ pointInShape()

virtual bool gnash::Video::pointInShape	(	std::int32_t	x,
		std::int32_t	y
	)		const

inlinevirtual

Return true if the given point falls in this DisplayObject's shape.

Parameters

x	Point x coordinate in world space
y	Point y coordinate in world space

Returns: Whether (x, y) is within the DisplayObject's bounds.

Implements gnash::DisplayObject.

§ setSmoothing()

void gnash::Video::setSmoothing ( bool b )

inline

Set whether smoothing is required.

Referenced by gnash::registerVideoNative().

§ setStream()

void gnash::Video::setStream ( NetStream_as * ns )

Set the input stream for this video.

References gnash::NetStream_as::setInvalidatedVideo().

§ smoothing()

bool gnash::Video::smoothing ( ) const

inline

Whether this Video object should request smoothing when scaled.

Referenced by gnash::registerVideoNative().

§ width()

int gnash::Video::width ( ) const

Get the width of the video.

The method depends on whether it is an embedded or a live stream. This returns 0 until the height is known, which for FLV streams is only after decoding. The value may possibly vary during playback.
