Return the number of available samples in the output FIFO.
During conversion, if the user does not specify an output buffer or
specifies an output buffer that is smaller than what is needed, remaining
samples that are not written to the output are stored to an internal FIFO
buffer. The samples in the FIFO can be read with avresample_read() or
avresample_convert().
