input-slave is very limited and starts showing issues when building
encoders using
capture cards. This use-case is usually combined with systems that are
just powerful enough
to capture audio and video with nothing to spare. Any inefficiency
will thus show up and running the input slave on
the video capture thread is one of them.

The input-slave system is an inefficiency that needs improvement IMHO.

A solution could be to give the input-slave its separate thread.
