3.3.3About the Encode Demo
Like the Encode + Decode demo, the Encode demo also encodes video. In addition, it also encodes speech. The speech source is the microphone.
The encoded data is written to files on the EVM’s hard disk drive. The possible filenames are demo.264, demo.mpeg4, demompeg4.g711, and demo264.g711. Older versions of these files are overwritten as needed.
Output is not decoded and sent to the display or speakers other than to show the settings and dynamic data collected about the load and rates.
Note that you can use only a speech encoder, not an audio encoder. The supported video algorithms are MPEG4 (.mpeg4 file extension) and H.264 (.264 file extension). The supported speech algorithm is G.711 (.g711 extension).
