Description

I always appreciate your work for the Opus codec.

In these days, I try to decode a .opus file with packet loss and to turn on and off the PLC and FEC procedures but the PLC and FEC look turned on always.

Even though I removed the PLC-related functions defined in silk/PLC.c, it doesn't show difference.

May I know how to turn off the procedures?

Research direction

Start with silk/PLC.c and the decoder path used for the .opus file; reproduce decoding with packet loss while examining how PLC and FEC are selected. Done means establishing whether an existing public control can disable them, or clearly defining the requested control if none exists.
