3.3.4 About the Decode Demo
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.
The supported video algorithms are H.264 (.264 extension) and MPEG4
(.mpeg4 file extension). The supported speech algorithm is G.711 (.g711
file extension).
The application runs on the ARM using Linux. The video and audio
signals are passed to decoders by the Codec Engine.
To use this demo from the command line, see Section 3.4, Running the
Demos from the Command Line.
