I'm trying to link a really simple GLES2 & EGL program using g++ 4.9.1, on a Ubuntu Trusty system. I'm using the mesa libraries. I'm getting linker errors for EGL functions: test.cpp:(.text+0x342): undefined reference to `eglGetDisplay' test.cpp:(.text+0x389): undefined reference to `eglInitialize' test.cpp:(.text+0x40f): undefined reference to `eglCreateContext' test.cpp:(.text+0x458): undefined reference to `eglCreatePbufferSurface' test.cpp:(.text+0x49e): undefined reference to `eglMakeCurrent' I am compiling test.cpp with g++ -std=c++0x -Wall -Werror -lEGL -lGLESv2 -o test test.cpp I've

First, thanks to fadden for your wonderful examples. I tried following this ContinuousCapture.java example, and produced the below program. 1) I am trying to display the image into TextureView in the native layer by getting its ANativeWwindow reference, and using ANative lock and unlockpost methods to acquire the BufferQueue and to fill the data. Ie: ANativeWindow_lock(*window, &buffer, NULL) ANativeWindow_unlockAndPost(*window); 2) At the same time i want to retrieve the data from this Surface and pass it to the encoder. Or, display it into another surface. As a first step, I have created the

I have to convert and display YUV420P images to RGB colorspace using the AMD GPU on a Freescale iMX53 processor (OpenGL ES 2.0, EGL). Linux OS, no X11. To achieve this I should be able to create an appropriate image holding the YUV420P data: this could be either a YUV420P/YV12 image type or 3 simple 8-bit images, one for each component (Y, U, V). glTexImage2D is excluded, because it's slow, the YUV420P frames are the results of a real time video decoding @25FPS and with glTexImage2D we can't keep the desired framerate. There's an alternative: eglCreateImageKHR/glEGLImageTargetTexture2DOES. The

I tried the program as shown in book OpenGL ES2 for Android, but it's not working!! I have tested in Odroid E, samsung s3, samsung y, samsung star!! the gl version suported returns 2, but i get 11-22 15:09:45.804: E/oGl-es v(9047): 2.0:131072 11-22 15:09:45.804: E/libEGL(9047): call to OpenGL ES API with no current context (logged once per thread) 11-22 15:09:45.804: E/unable to(9047): createShader 11-22 15:09:45.804: E/libEGL(9047): call to OpenGL ES API with no current context (logged once per thread) 11-22 15:09:45.804: E/unable to(9047): createShader 11-22 15:09:45.804: E/libEGL(9047):

By EGL, we can create EGLSurface, I can see there are three choices there: * EGL_WINDOW_BIT * EGL_PIXMAP_BIT * EGL_BUFFER_BIT The first one is for on-screen processing, the second one is for off-screen, so I use EGL_PIXMAP_BIT like this: // Step 1 - Get the default display. EGLDisplay eglDisplay = eglGetDisplay((EGLNativeDisplayType) 0); if ((eglDisplay = eglGetDisplay(EGL_DEFAULT_DISPLAY)) == EGL_NO_DISPLAY) { LOGH(

I modified the sample, though. The reason was because I got an IllegalArgumentException in GLSurfaceView.BaseConfigChooser.chooseconfig, so i replaced mGLSurfaceView.setEGLContextClientVersion( 2 ); The new OnCreateMethod: protected void onCreate( Bundle savedInstanceState ) { super.onCreate( savedInstanceState ); mGLSurfaceView = new GLSurfaceView( this ); mGLSurfaceView.setEGLConfigChooser( new EGLConfigChooser() {

I was trying to build the code which uses GraphicBuffer with ndk-r9d. but It is saying GraphicBuffer is not declared in this scope. The same comments for eglCreateImageKHR and glEGLImageTargetTexture2DOES. I have added EGL/eglext.h and GLES2/gl2ext.h . I tried to include ui/GraphicBuffer.h but it is not taking it. Is there another header file to be added ? The code given below I have added to avoid use of glTexSubImage2D(
