Hello,
attached patch makes
- the speex library optional (i.e. the speex resampler and the speex
acoustic echo canceller, AEC)
- the Adrian AEC implementation in the module-echo-cancel optional
reducing dependencies and unneeded code is desirable in embedded scenarios
note that the patch changes the default resampler in pa_resampler_new() in
case speex is not available, so
speex -> libsamplerate -> ffmpeg
please comments
regards, p.
