I am very new to OpenGL

Trying to blend RGB & BGRA raw images.

* RGB is backgroung image
* RGBA is foregroubng image

With the below source getting the output only ,"osd\_raw" image .Blending is not happening.

In the below code loading the 2 raw images .
Creating 2 textures & binding with it.
Used glBlendFunc for blending. 
The output is not getting blended.

Please tell me where it's getting wrong.

```
void display()
{

    GLuint texture[2];
    int width = 960;
    int height = 540;
    unsigned char *osd_raw = loadFile("./osd.raw");
    unsigned char *video_raw = loadFile("./video.raw");

    glClearColor(0.1, 0.1, 0.1, 0.0);
    glClear(GL_COLOR_BUFFER_BIT);

    glEnable(GL_TEXTURE_2D);
    glGenTextures(2, texture);

    glEnable( GL_BLEND);
    glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA);

    glBindTexture(GL_TEXTURE_2D, texture[0]);
    glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB, width, height, 0, GL_RGB, GL_UNSIGNED_BYTE, video_raw);
    glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_REPEAT);
    glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_REPEAT);
    glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR);
    glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR);
    glTexEnvf(GL_TEXTURE_ENV, GL_TEXTURE_ENV_MODE, GL_MODULATE);

    glBindTexture(GL_TEXTURE_2D, texture[1]);
    glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, width, height, 0, GL_BGRA, GL_UNSIGNED_BYTE, osd_raw);
    glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_REPEAT);
    glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_REPEAT);
    glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR);
    glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR);
    glTexEnvf(GL_TEXTURE_ENV, GL_TEXTURE_ENV_MODE, GL_MODULATE);

    glBegin(GL_QUADS);
    glTexCoord2f(0, 0);
    glVertex3f(-1, -1, 0);
    glTexCoord2f(0, 1);
    glVertex3f(-1, 1, 0);
    glTexCoord2f(1, 1);
    glVertex3f(1, 1, 0);
    glTexCoord2f(1, 0);
    glVertex3f(1, -1, 0);
    glEnd();

    glFlush();
}

int main(int argc, char** argv)
{
    glutInit(&argc, argv);
    glutInitDisplayMode(GLUT_SINGLE | GLUT_RGBA);

    glutInitWindowSize(960, 540);
    glutInitWindowPosition(0, 0);
    glutCreateWindow("glut test");

    glutDisplayFunc(display);
    glutMainLoop();
    return 0;
}
