[Bug report]OPUS, array out of range

Hi Lin,

I got one of the devs to check if setting DECODER_NUM_CHANNELS to 2 would affect the final code size of the library in the SR3 project(which only uses the encoder) and it did not, i.e. the decoder it is optimized out. However, if you're only using the decoder and not the encoder, then you should set DECODER_NUM_CHANNELS to 2. We have not done as much testing of the decoder part of our OPUS port as we have with the encoder( since this is the only part we're using), but it should work fine. Let me know if it does not.

Best regards

Bjørn

I only used opus silk decoder in my project, and encoder had been optimized out after compiling. Does it have any influence if I only use decoder?

Hi Lin,

Thank you for letting us know.

I agree that this looks like a bug.

The Smart Remote 3 firmware only uses the OPUS library for encoding since the the audio is only going from the remote to the Ubuntu host. The OPUS library is optimized for size in the SR3 firmware, so unless you're adding support for audio in both directions, then the SILK encoder is most likely optimized out. Are you adding support for encoding in a remote product?

Best regards
