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.

The latter can do everything the former can do, but also handle conditions
the former cannot like multiple header #includes and checking for headers
and functions in a single test program, which is necessary for certain
library tests.
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.
Should fix "libavcodec/h264_refs.c:372:13: warning: variable 'i' is used uninitialized whenever switch default is taken"

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.

With some old libva versions <va/va.h> does not automatically include
the per-codec subsidiary headers, so we need to include the right one
explicitly ourselves.
Introduced in b7e78c7 and 93ae68d.
Fixes#5835.
The paletteuse debug options that are not part of the official API are
not included (debug_kdtree and color_search).

This is simpler and fixes an out of array read, fixing it with AVBuffers
would be more complex
