AME Scripting Guide: encode(src, dst)

Hi.

In AME Scripting Guide, in the Return description of point
5.1.6 EncoderHost.createEncoderForFormat()

mentions the encode(src,dst) method, which sets the source and result files.

But this command doesn't actually work:

(Adobe Extendscript Toolkit)

The encode(src, dst) method is absent in the methods and properties of the Encoder class instance.

How to set the source and destination files before the EncoderHost.runBatch command()?
