Opus encoder.
This is a native FFmpeg encoder for the Opus format. Currently its in development and
only implements the CELT part of the codec. Its quality is usually worse and at best
is equal to the libopus encoder.
@subsection Options
@table @option
@item b
Set bit rate in bits/s. If unspecified it uses the number of channels and the layout
to make a good guess.
@item opus_delay
Sets the maximum delay in milliseconds. Lower delays than 20ms will very quickly
decrease quality.
