3.3.2 About 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).
The application runs on the ARM using Linux. The video signal is passed
to video encoders and decoders on the DSP by the Codec Engine.
Shared memory is used when passing data.
To use this demo from the command line, see Section 3.4, Running the
Demos from the Command Line.
