Ok thanks! :D
But for now I merged code in sample_demo7 .cpp and .h files to avoid issues.
But I have an other (I know...again!) problem!

As said before I try to display video on a CEGUI window. To achieve that I took example from NeHe tutorial Lesson35.
Everythink work fine until I create texture by loading frame from memory!
An exception occured!

Here my code to do this:

Code: Select all

   Texture* videoFrame;
   *videoFrame   = System::getSingleton().getRenderer()->createTexture();

   videoFrame->loadFromMemory(imgVid, Size(256,256), CEGUI::Texture::PF_RGB);

   // Destroy previous ImageSet use to display video
   ImagesetManager::getSingleton().destroyImageset("videoFrame");

   // Update video
   ImagesetManager::getSingleton().createImageset("videoFrame",(*videoFrame));
   
   Window* img = WindowManager::getSingleton().getWindow("Demo7/Window4Video/ZoneVideo");

   img->setProperty("Image", "set:videoFrame image:full_image");


imgVid is mu bmp image converting by:

Code: Select all

DrawDibDraw (hdd, hdc, 0, 0, 256, 256, lpbi, pdata, 0, 0, width, height, 0);

as write in NeHe tutorial!

Maybe someone can help me?
Thank you!

Hi! Some news some ones that matter lol!

Video works with vfw (altough displaying surface is cut and video is upside down, maybe fixable with "iluFlipImage();").
With FFMPEG it still does not work but I think it is due to video convertion (using sws_scale).

Code used to display video:

Code: Select all

ImagesetManager::getSingleton().getImageset("videoFrame")->getTexture()->loadFromMemory(imgVid,width, height, CEGUI::Texture::PF_RGB);
Window* img = WindowManager::getSingleton().getWindow("Demo7/Window4Video/ZoneVideo");
img->setProperty("Image", "set:videoFrame image:full_image");

C U!

Hello! Just a little up for this issue not fixed yet! :D
Thank you!

But type of setPosition is not the same with RenderingWindow class (float) and Window class(UDim). To get float data I try:

Code: Select all

Window win->getPosition().d_x.asAbsolute(1.0f);
but It seams that it is not the same reference than RenderingWindow ::getPosition() method.
Since I use float datas in my trajectory calculation function I need float!

Can you help me please?
Thank you!

marsh>> sorry I edit instead of quote but it still ok for share you what I have done!

I think there is a bug of rendering (or maybe configuration missing):
When I run trunk's demo7 under VC++2005 express with OpenGL, window renders white.
With DirectX it renders fine. I had to install Microsoft SDK so I installed Window Server 2008.
I saw on an older topic that some had a problem close so maybe you can help me!
Thanks :wink: !

Hello!

I want to achieve a translation with a window like you can make in this example (sorry it is in french but translation french translation is...translation! :D ):
http://www-evasion.imag.fr/Membres/Antoine.Bouthors/teaching/opengl/opengl3.html (translation section).

The window turn on a O-center and OM-beam circle thank to this(with openGL):

Code: Select all

glTranslated(cos(a),0,sin(a));


So I try to do the same with this code:

Code: Select all

window.setPivot(CEGUI::Vector3(cos(valPivot),0,sin(valPivot)));

in the "realiseGeometry" method of a CEGUI::RenderEffect subclass.
Of course I update valPivot in the update method.

Of course it would be too easy to work!
Maybe someone could help me please?
