Note: You must run the Encode demo before you can run the Decode demo unless you have placed appropriately-named audio and video files on the EVM’s NAND flash storage device. If you see a message that says "File Not Found", please run the Encode demo.

The Decode demo plays audio/speech and video files you select. You can select a source video file and a source audio or speech file. Use the left and right arrow buttons to choose from the demo files and the files created by the Encode demo, which are stored on the EVM’s NAND flash. The decoded signals are sent to your video display and speakers.
