    most often you can not really do that. The video is usually player with direct screen access and trying to draw something on top of it will most often fail, and simply causse huge flickering.

    Hi,
    I've seen the demo apps for Augmented Reality and know for sure that this is doable.

    I am looking for a sample code on this.

    Thanks.

    If you have access to the video frame to be rendered (if you are using your own decoder or getting decoded frame from the inbuilt decoding engine), then you can take the video frame to be rendred and the image to be overlayed and apply video mixing algorithms like overlay, chroma keying or alpha blending.
