android - 使用GLES2.0绘制YUV时如何获取默认向量

Question

该程序在ios和大多数Android设备上运行良好，而某些Android设备会显示混乱，而我可以通过修改以下两个向量的值来解决它。我的问题是：有什么聪明的方法可以知道设备的向量吗？例如，通过 Surface、GPU...

static const GLfloat squareVertices[] = {
    -1.0f, -1.0f,
    1.0f, -1.0f,
    -1.0f,  1.0f,
    1.0f,  1.0f,
};

static const GLfloat coordVertices[] = {
    0.0f, 1.0f,
    1.0f, 1.0f,
    0.0f,  0.0f,
    1.0f,  0.0f,
};


glClear(GL_COLOR_BUFFER_BIT);

glUseProgram(_program);

GLuint textureUniformY = glGetUniformLocation(_program, "SamplerY");
GLuint textureUniformU = glGetUniformLocation(_program, "SamplerU");
GLuint textureUniformV = glGetUniformLocation(_program, "SamplerV");
glVertexAttribPointer(ATTRIB_VERTEX, 2, GL_FLOAT, 0, 0, squareVertices);
glEnableVertexAttribArray(ATTRIB_VERTEX);

glVertexAttribPointer(ATTRIB_TEXTURE, 2, GL_FLOAT, 0, 0, coordVertices);
glEnableVertexAttribArray(ATTRIB_TEXTURE);
