Display video under GTK+

["Daniel Ding" <danielding hotmail com>]

Hi,

I am trying to display video under GTK+. I am using the function:

    gdk_draw_rgb_image (darea->window,
	darea->style->fg_gc[GTK_STATE_NORMAL],
        X_START, Y_START, COL_MAX, ROW_MAX,
        GDK_RGB_DITHER_MAX, pBufferRGB, COL_MAX * 3);
   // GDK_RGB_DITHER_NORMAL, GDK_RGB_DITHER_MAX

The RGB data in the buffer is 24 bits. The video is blurred, and color 
disappears.

Any advices are highly appreciated.

Daniel
