Summary: SoX can't encode amr-wb.

Initial Comment:
Discussed on the mailing list.

SoX can't encode amr-wb... because it's compiled with libopencore-amrwb.

But libopencore-amrwb is a DEcoder.

Needs to be compiled with vo-amrwbenc ENcoder.


sox -d output.amr-wb
sox WARN formats: amr-wb can't encode at 48000Hz; using 16000Hz
sox WARN formats: amr-wb can't encode stereo; setting channels to 1
sox FAIL formats: can't open output file `output.amr-wb'
SoX was compiled without AMR-WB encoding support.

Message:
I've had another look at this problem.
Using Ubuntu, SoX is insisting on compiling against libopencore-amrnb
libopencore-amrwb.
I have libopencore-amrnb-dev libopencore-amrwb-dev packages installed
because they are used when compiling other programs eg FFmpeg.
My workaround is to uninstall those two dev packages and compile SoX
against temporary local static builds of amrnb and amrwb.
Then re-install the dev packages afterwards.

My build script is attached.
Nobody's shown any interest in this bug so I'm gonna mark it as 'fixed'

Now SoX will convert to amr-nb AND amr-wb.
