[opus] [EXTERNAL] Re: Developing OPUS on TI CC3220

Jean-Marc,

Thanks for the response and the helpful info.

I am trying to get the library to build without using the pseudostack define, and use either VAR_ARRAYS or ALLOC, but it seems the global stack is not defined.

Where do can I define this in my example?

Hi Vince,

Normally, Opus should work fine on the CC3220, though real-time encoding may be a bit tight depending on what configuration you choose. You'll probably want to configure with --enable-fixed-point and --disable-float-api (or define FIXED_POINT and DISABLE_FLOAT_API if you don't use autoconf).

The encoder has a bunch of run-time settings that you may want to set, depending on your application. These include bitrate, complexity (probably a low setting for that that chip), and bitrate management (CBR/VBR/CVBR).

In the end, aside from the complexity requirements, you should need to do anything special to get Opus running on your chip.

Cheers,

	Jean-Marc
