Convert the input audio format to the specified formats.
The filter accepts a string of the form:
"@var{sample_format}:@var{channel_layout}:@var{packing_format}".
"@var{sample_format}:@var{channel_layout}".
@var{sample_format} specifies the sample format, and can be a string or
the corresponding numeric value defined in @file{libavutil/samplefmt.h}.
@var{sample_format} specifies the sample format, and can be a string or the
corresponding numeric value defined in @file{libavutil/samplefmt.h}. Use 'p'
suffix for a planar sample format.
@var{channel_layout} specifies the channel layout, and can be a string
or the corresponding number value defined in @file{libavutil/audioconvert.h}.
@var{packing_format} specifies the type of packing in output, can be one
of "planar" or "packed", or the corresponding numeric values "0" or "1".
The special parameter "auto", signifies that the filter will
automatically select the output format depending on the output filter.
