Unigine::WidgetSpriteVideo Class
Header: | #include <UnigineWidgets.h> |
Inherits from: | WidgetSprite |
This class is used to create a virtual monitor that plays a video file (currently only *.OGV files are supported). It can be synchrozied with playback of the ambient sound or the directional sound source.
The following example illustrates how to play a video-file on the system GUI or a GUI object using the WidgetSpriteVideo class.
Create a C++ component named VideoSprite and copy the code below to the corresponding files:
Source code (C++)
#pragma once
#include <UnigineComponentSystem.h>
class VideoSprite :
public Unigine::ComponentBase
{
public:
COMPONENT_DEFINE(VideoSprite, Unigine::ComponentBase);
COMPONENT_INIT(init);
// path to the video file to play (only *.OGV type is supported)
PROP_PARAM(File, file_name, "");
private:
// sprite video widgets
Unigine::WidgetSpriteVideoPtr TVscreen;
Unigine::WidgetSpriteVideoPtr MAINscreen;
void init();
};
Source code (C++)
#include "VideoSprite.h"
#include <UnigineGui.h>
REGISTER_COMPONENT(VideoSprite);
using namespace Unigine;
void VideoSprite::init()
{
// creating the first sprite video widget that plays a file_name video file on the system GUI
MAINscreen = WidgetSpriteVideo::create(Gui::getCurrent(), file_name, 1);
// setting size and position of the second sprite video widget on the screen
MAINscreen->setPosition(100, 100);
MAINscreen->setWidth(400);
MAINscreen->setHeight(225);
MAINscreen->arrange();
// adding the sprite video widge to the system GUI
Gui::getCurrent()->addChild(MAINscreen, Gui::ALIGN_OVERLAP | Gui::ALIGN_BACKGROUND);
// setting looped playback mode
MAINscreen->setLoop(1);
// launching playback
MAINscreen->play();
// checking if the node to which the component is assigned is a GUI Object
if (node->getType() != Node::OBJECT_GUI)
{
Log::message("Node is not a GUI Object!\n");
return;
}
ObjectGuiPtr GUIObject = checked_ptr_cast<ObjectGui>(node);
// creating the second sprite video widget that plays a file_name video file on the GUI object
TVscreen = WidgetSpriteVideo::create(GUIObject->getGui(), file_name, 1);
// adjusting the size of the widget to fit the size of the GUI object
TVscreen->setWidth(GUIObject->getScreenWidth());
TVscreen->setHeight(GUIObject->getScreenHeight());
// adding the sprite video widget to the GUI object
GUIObject->getGui()->addChild(TVscreen, Gui::ALIGN_OVERLAP | Gui::ALIGN_BACKGROUND);
// setting looped playback mode
TVscreen->setLoop(1);
// launching playback
TVscreen->play();
}

WidgetSpriteVideo Class
Members
static WidgetSpriteVideoPtr create ( const Ptr<Gui> & gui, const char * name = 0, int mode = 1 ) #
Constructor. Creates a new sprite that plays video and adds it to the specified GUI.Arguments
- const Ptr<Gui> & gui - GUI, to which the new sprite will belong.
- const char * name - Path to a video file.
- int mode - YUV flag: 1 if conversion to RGB should be performed by the GPU, 0 - if by the CPU.
static WidgetSpriteVideoPtr create ( const char * name = 0, int mode = 1 ) #
Constructor. Creates a new sprite that plays video and adds it to the Engine GUI.Arguments
- const char * name - Path to a video file.
- int mode - YUV flag: 1 if conversion to RGB should be performed by the GPU, 0 - if by the CPU.
void setAmbientSource ( const Ptr<AmbientSource> & source ) #
Synchronizes video playback to the ambient sound source playback.Arguments
- const Ptr<AmbientSource> & source - Ambient sound source according to which video playback will be synchronized.
Ptr<AmbientSource> getAmbientSource ( ) const#
Returns the ambient sound source according to which video playback is synchronized.Return value
Ambient sound source.void setLoop ( int loop ) #
Sets a value indicating if the video should be looped.Arguments
- int loop - Positive number to loop the video, 0 to play it only once.
int getLoop ( ) const#
Returns a value indicating if the video is looped.Return value
Positive number if the video is looped; otherwise, 0.bool isPlaying ( ) const#
Returns a value indicating if the video is being played at the moment.Return value
1 if the video is being played; otherwise, 0.void setSoundSource ( const Ptr<SoundSource> & source ) #
Synchronizes video playback to the sound source playback.Arguments
- const Ptr<SoundSource> & source - Sound source according to which video playback will be synchronized.
Ptr<SoundSource> getSoundSource ( ) const#
Returns the sound source according to which video playback is synchronized.Return value
Sound source.bool isStopped ( ) const#
Returns a value indicating if the video is stopped at the moment.Return value
1 if the video is stopped; otherwise, 0.void setVideoTime ( float time ) #
Rewinds or fast-forwards the video to a given time.Arguments
- float time - Time in seconds.
float getVideoTime ( ) const#
Returns the time of the currently played frame.Return value
Time in seconds.void setYUV ( int yuv ) #
Sets a flag for YUV conversion.Arguments
- int yuv - Mode flag: 1 if conversion to RGB should be performed by the GPU, 0 if it is converted by the CPU.
int getYUV ( ) const#
Returns a flag for YUV conversion.Return value
1 if conversion to RGB is performed by the GPU, 0 if it is converted by the CPU.void play ( ) #
Starts playing video.void stop ( ) #
Stops playing video. This function saves the playback position so that playing of the file can be resumed from the same point.The information on this page is valid for UNIGINE 2.19.1 SDK.
