As it is already written in the documentation, BMD DeckLink cards
are capable of capturing 2, 8 or 16 audio channels (for SDI Inputs).
Currently the value is hardcoded to 2. Introduces new option.

Incidentally `-y` also collides with avconv global options.
Update x11grab to match and document the option.

* rdp/dshow_crossbar:
dshow: fix docu escapes
dshow: some devices only list themselves under "Video sources" but actually have both video and audio output pins, so make the audio pins accessible by video source name.
dshow: add options for allowing filter popup configuration dialogs to be presented to the user
dshow: introduce support for crossbar [multiple input selectable] devices
dshow: drop initial audio packets with weird timestamps
dshow: use non deprecated api
dshow: miscellaneous tweaks
dshow: allow selecting devices by an alternative name (workaround for devices with symbols in them), allow specifying capture pins by name and alternative (unique) name

FFmpeg mix devices and file formats when -formats option is used.
This commit adds a -devices param to list devices only.

Based on original code by Christophe Gisquet in 2010, updated to work
with current ffmpeg APIs.
Supports grabbing a single window or an area of the screen, including
support for multiple monitors (Windows does funky stuff with negative
coordinates here).
I've moved most of the configuration to AVOptions; the input file name
is now only the string "desktop", or "title=<windowname>" to select a
single window. The AVOptions are the same as x11grab where possible.
Code has been added to support a "show_region" mode, like x11grab, which
will draw a rectangle on the screen around the area being captured.
Instead of duplicating code for paletted image handling, I make use of
the GDI API's ability to output DIB (BMP) images, which can be run
through ffmpeg's existing BMP decoder.

Also disable it by default since it looks currently buggy. The
usefulness of such library is mostly limited to backward compatibility
with very old devices.
An input channel could have been previously set with another application, like
v4l2-ctl, so if no input channel is specified use the previosly selected one.
