Ticker Sample

Description

This sample uses the Video Mixing Renderer to blend video and text. It uses the IVMRMixerBitmap (or IVMRMixerBitmap9) interface to blend text onto the bottom portion of the video window.

The application creates a bitmap with a default text string and scrolls it across the bottom of the screen. To change the text, choose Set text string... from the Ticker menu. To set the font, choose Set font... from the Ticker menu. If you select Use static image from the Ticker menu, the application switches from a dynamic text string to a a static bitmap image.

Two versions of this sample are available, one for the VMR-7 and one for the VMR-9.
