我有我的OpenGL渲染的问题。 RAM存储器荒谬生长至整个系统冻结点。 我已经确定,如果我评论了整个渲染功能,无记忆可言增长。 因此,问题是,我的OpenGL渲染功能可能的东西来分配内存,我不释放它。
你能确定是什么问题?
PS:里面的,如果实际运行一次性的事情,所以内存的它配置,只出现一次
这是我的OpenGL渲染功能:
void OpenGlVideoQtQuickRenderer::render()

if (this->firstRun) {
std::cout << "Creating QOpenGLShaderProgram " << std::endl;
this->firstRun = false;
program = new QOpenGLShaderProgram();
initializeOpenGLFunctions();
//this->m_F = QOpenGLContext::currentContext()->functions();
datas[0] = new unsigned char[width*height]; //Y
datas[1] = new unsigned char[width*height/4]; //U
datas[2] = new unsigned char[width*height/4]; //V
std::cout << program->addShaderFromSourceCode(QOpenGLShader::Fragment, tString2) << std::endl;
std::cout << program->addShaderFromSourceCode(QOpenGLShader::Vertex, vString2) << std::endl;
program->bindAttributeLocation("vertexIn",A_VER);
program->bindAttributeLocation("textureIn",T_VER);

}
program->bind();
