装入统一的矩阵1104 GL_Invalid_Operation的Andr​​oid 2.0 OpenGLES [英] Load Uniform Matrix 1104 GL_Invalid_Operation Android OpenGLES 2.0

问题描述

我的工作落实渲染到纹理在Android 4.3以上版本（OpenGLES 2.0）

I am working on implementing rendering to texture on Android 4.3+ (OpenGLES 2.0)

我收到我的并条机（）方法，以下错误：

I am getting the following error in my DrawFrame() method:

01-15 13:40:07.545: W/Adreno-ES20(23709): <__load_uniform_matrix:1104>: GL_INVALID_OPERATION

莫非这个问题从茎建立 EGL14.eglChooseConfig（mEGLDisplay，configsAttribs，0，CONFIGS，0，configs.length，numConfigs，0）; 与

private int[] version, configsAttribs = {
        EGL14.EGL_RED_SIZE, 8,
        EGL14.EGL_GREEN_SIZE, 8,
        EGL14.EGL_BLUE_SIZE, 8,
        EGL14.EGL_RENDERABLE_TYPE, EGL14.EGL_OPENGL_ES2_BIT,
        EGL_RECORDABLE_ANDROID, 1,
        EGL14.EGL_NONE

但是使用连接到FBO以下质地

But using the following texture connected to the FBO

    // generate the textures
    GLES20.glTexImage2D(GLES20.GL_TEXTURE_2D, 0, GLES20.GL_RGBA, rain.width, rain.height, 0, GLES20.GL_RGBA, GLES20.GL_UNSIGNED_SHORT_4_4_4_4, juliaTexBuff);

注意RGBA4444的discrepency在EGL而不是RGBA8888？

Notice the discrepency of RGBA4444 as opposed to RGBA8888 in EGL?

推荐答案

但问题是调用glUseProgram之前加载一个统一的变量中。如果我把包含glGetUniform4fv（块后调用）它显然失败，因为它不知道是哪里的制服是因为程序被加载。

The problem was during loading a uniform variable before calling glUseProgram. If I put the call after the block that contained glGetUniform4fv() it obviously fails because it doesn't know where the uniform is because the program is loaded.
