Hi,how are you?
We use Opengl 2.0 to develop a video programme on android with nexus one.
We find that the fuction glTexImage2D is too slow,but we write a
shader programme accord to the sample GL2JNILib.
I guess the GPU is not working, why it happened? how to fix it?
help me,please.Thank you very much.
----------------------some important code---------------------------
VideoView(Context context)
{
super(context);
// m_Activity=(hello)context;
m_AndroidHolder = getHolder();
m_AndroidHolder.addCallback(this);
m_AndroidHolder.setType(SurfaceHolder.SURFACE_TYPE_GPU);
m_AndroidHolder.setFormat(PixelFormat.RGB_565);
.
.
.}
------------------------------
public void initEGL()
{
mEGL = (EGL10)EGLContext.getEGL();
mGLDisplay = mEGL.eglGetDisplay(EGL10.EGL_DEFAULT_DISPLAY);
int[] curGLVersion = new int[2];
mEGL.eglInitialize(mGLDisplay, curGLVersion);
ConfigChooser configChooser= new ConfigChooser(5, 6, 5, 0, 0, 0);
mGLConfig = configChooser.chooseConfig(mEGL,mGLDisplay);
mGLSurface = mEGL.eglCreateWindowSurface(mGLDisplay,
mGLConfig,m_View.m_AndroidHolder, null);
int[] attrib_list = {0x3098, 2, EGL10.EGL_NONE };
mGLContext = mEGL.eglCreateContext(mGLDisplay, mGLConfig,
EGL10.EGL_NO_CONTEXT, attrib_list);
mEGL.eglMakeCurrent(mGLDisplay, mGLSurface, mGLSurface, mGLContext);
}
------------------------------
glActiveTexture ( GL_TEXTURE0 );
glBindTexture ( GL_TEXTURE_2D, userData.textureId[0] );
glUniform1i ( userData.samplerLocY, 0);
glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MAG_FILTER,GL_LINEAR);
glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MIN_FILTER,GL_LINEAR);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S,
GL_CLAMP_TO_EDGE);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T,
GL_CLAMP_TO_EDGE);
glTexImage2D(GL_TEXTURE_2D, 0, GL_LUMINANCE, width, height, 0,
GL_LUMINANCE, GL_UNSIGNED_BYTE, pict->data[0]);
