Re: [codec] I-D Action:draft-ietf-codec-opus-05.txt

Dear Jean-Marc,
I have tested V0.9.2 code, and find if enable DTX, it will return from range checking, error code is Error: Range coder state mismatch between encoder and decoder.
And if not define OPUS_TEST_RANGE_CODER_STATE, the decoded file has sharp noise in the silence area. The left channel of test.wav is origin voice, and the right channel is encode/decode with DTX enabled.

Please check it.

Thanks
Keith

Hi,

Just to let you know that the main change in that latest version is the 
ability to decode multi-frame packets. That code has received very 
little testing, so don't be surprised if it breaks. However, I did some 
amount of testing to at least make sure that random inputs do not cause 
buffer overruns and similar security issues.

Cheers,

	Jean-Marc
