Problem is that ffmpeg now uses filters internally. So as soon as there is
video transcoding, buffersrc and buffersink are necessary, even if no
filters were built at all. Still, ffmpeg can still be used for audio
transcoding and stream copy, so it makes marginally sense to allow it.

At some point, it was decided that vsrc_buffer can not be disabled with the
standard configuration system. The rest is a matter of consistency:
vsrc_buffer does not have a different status than asrc_buffer and
[av]sink_buffer (except that audio filtering is not yet ready in ffmpeg, but
that should change in time).
