and packets (for example ffmpeg itself) to process raw byte
streams (like aviocat).

Options are freed from the generic code now, there is no need to call
av_opt_free() from the filter.

It now allows an arbitrary number of inputs, not just two.

Otherwise some code might mistakenly think it is allowed to unref those
buffers, which would lead to double unref.
