3.3.2About the Encode + Decode Demo
The Encode + Decode demo allows you to record and playback video. Video comes from the camera, is encoded, then decoded, and then sent to the LDC display.
The Encode + Decode does only video processing; it does not encode and decode audio or speech. The supported video algorithm is H.264 Baseline Profile (.264 file extension).
