First, I use opusenc to generate a opus file which input is a 9-channels wav file. The opusenc can work. Then, I use opusdec to transform the generated opus file to wav file, but opusdec can't work.

I can confirm the same problem with
libopus 1.3.1, libopusenc 0.2.1 and opus-tools 0.2
With up to 8 channels, it works just fine.
API says the channel count can be up to 255:
Is this a known limitation of opusdec?
