<p class="MsoNormal">Hi,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We are rebasing our audio compression subsystem using OPUS rather than SPEEX. The platform is Android but this piece is written in C code: we need to support armv5/armv7/x86 architectures…. and we use the released opus-1.1beta package from
<a href="http://downloads.xiph.org/releases/opus/opus-1.1-beta.tar.gz">here</a>.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">A lot of our OPUS build system + code to drive the audio compression has been reused from our SPEEX port since there are a lot of similarities between the OPUS and SPEEX build flags and APIs.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I can build and run OPUS on the device using the default FLOATING point. However, for latency reasons, we are considering building with FIXED_POINT (like we do for SPEEX). Then I have the link error below. a macro is not defined and a method
is not implemented when compiling with FIXED_POINT. I did a search on your code base and indeed that seems to be the problem.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I might be missing something but please verify on your side and keep me posted about your results. I also attached the python file that list the files we are building for FIXED POINT and FLOATING POINT mode as well as our config.h file
adapted from our SPEEX implementation.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks,<o:p></o:p></p>
