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.

Member Function Documentation

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.

void gnash::Video::construct ( as_object * init = 0 ) [virtual]

Register this video instance as a live DisplayObject.

Reimplemented from gnash::DisplayObject.

References gnash::DisplayObject::saveOriginalTarget().

void gnash::Video::display	(	Renderer &	renderer,
		const Transform &	xform
	)		`[virtual]`

Render the DisplayObject.

All DisplayObjects must have a display() function.

Implements gnash::DisplayObject.

References assert, gnash::DisplayObject::transform(), gnash::Renderer::drawVideoFrame(), and gnash::DisplayObject::clear_invalidated().

SWFRect gnash::Video::getBounds ( ) const [virtual]

Implements gnash::DisplayObject.

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.

References gnash::NetStream_as::videoHeight().

void gnash::Video::markOwnResources ( ) const [protected, virtual]

Mark video-specific reachable resources.

video-specific reachable resources are:

Associated NetStream if any (_ns)

Reimplemented from gnash::DisplayObject.

References gnash::ActiveRelay::setReachable().

virtual bool gnash::Video::pointInShape	(	boost::int32_t	x,
		boost::int32_t	y
	)		const `[inline, virtual]`

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.

References gnash::DisplayObject::pointInBounds().

void gnash::Video::setSmoothing ( bool b ) [inline]

Set whether smoothing is required.

References gnash::key::b.

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

Set the input stream for this video.

References gnash::NetStream_as::setInvalidatedVideo().

bool gnash::Video::smoothing ( ) const [inline]

Whether this Video object should request smoothing when scaled.

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.
