Chromaprint fingerprinter muxers.
Chromaprint fingerprinter.
To enable compilation of this filter you need to configure FFmpeg with
@code{--enable-chromaprint}.
This muxer feeds audio data to the Chromaprint library,
which generates a fingerprint for the provided audio data. See @url{https://acoustid.org/chromaprint}

silence detection. Silence detection can only be used with version 3 of the
algorithm.
Silence detection must be disabled for use with the AcoustID service. Default is -1.
@item algorithm @var{version}
Select version of algorithm to fingerprint with. Range is @code{0} to
@code{4}. Version @code{3} enables silence detection. Default is @code{1}.
