Useful when the amerge filter parameters are generated from a script based on
the number of input streams, by allowing 1 input it does not have to be handled
specially.

The split filter also allows 1 output, so it is more consistent to allow
merging 1 input as well.

This is mostly useful for muxers that wrap other muxers, such as dashenc
and segment. The actual duplicated bitstream filtering is largely harmless,
but delaying the header can cause problems when the muxer intended the header
to be written to a separate file.

The cuvid parser is basically undocumented, and although you'd
think that a failed callback would result in the overall parse
call returning an error, that is not true.

So, we end up silently trying to keep going as if nothing is wrong,
which doesn't achieve anything.

Solution: check the internal error flag every time.

MP4 media containing VP9 using superframes (such as
https://github.com/Netflix/vp9-dash/raw/master/DASH-Samples/Fountain_2997_0560kbps_640x480_4x3PAR.ivf_DashUnencrypted.ismv)
does not decode correctly with the built-in VP9 decoder because
superframes are passed to the decoder whole rather than split into
individual frames.
