About 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).
