Hi, I tried the DRED with opus_demo and found the the decoded dred_offset < 0 sometimes. In my understanding, the dred_offset should never be less than zero.

The command line is: "./opus_demo voip 16000 1 48000 -loss 50 -dec_complexity 6 -dred 50 speech.pcm speech_out.pcm" I print the dred_offset:
