libvo-amrwbenc


VisualOn Adaptive Multi-Rate Wideband encoder.

Requires the presence of the libvo-amrwbenc headers and library during configuration. You need to explicitly configure the build with --enable-libvo-amrwbenc --enable-version3.

This is a mono-only encoder. Officially it only supports 16000Hz sample rate, but you can override it by setting 'strict' to 'unofficial' or lower.

'b'

Set bitrate in bits/s. Only the following bitrates are supported, otherwise libavcodec will round to the nearest valid bitrate.

'6600'
'8850'
'12650'
'14250'
'15850'
'18250'
'19850'
'23050'
'23850'
'dtx'

Allow discontinuous transmission (generate comfort noise) when set to 1. The default value is 0 (disabled).
