`-s` parameter now sets audio only to following video capture, just like
`-F` (capture filter) does.
This allows different setting for different audio connectors for
different video sources, namely for switcher, eg.:
uv -t switcher -s analog -t decklink:device=1 -s embedded -t \
decklink:device=2

* video_capture_params is basically intended as a linked list of video capture
|
|
* parameters. It is used for structured capturers like `aggregate` or `switcher`,
|
|
* which work as a master and initialize its slaves. The structure is used to hold
|
|
* individual devices' parameters (namely per-device capture filter).
