152902f379 doc: Add FAQs about running in background (rev 2)
Add two FAQs about running FFmpeg in the background.
The first explains the use of the -nostdin option in
a straightforward way. Text revised based on review.

The second FAQ starts from a confusing error message,
and leads to the solution, use of the -nostdin option.
The purpose of the second FAQ is to attract web searches
from people having the problem, and offer them a solution.

Add an anchor to the Main Options section of the ffmpeg
documentation, so that the FAQs can link directly there.

80ef3c8360 ffmpeg: Allow "-to" on input files in addition to "-t"
For some strange reason "-t" option was only implemented
for input files while both "-t" and "-to" were available
for use for output files. This made extracting a range from
input file inconvenient.

This patch enables -to option for input so one can do

    ffmpeg -ss 1:23:20 -to 1:27:22.3 -i myinput.mkv ...

e0436ddaa4 ffmpeg options: Enable trailing ? for map_channel
The -map option allows for a trailing ? so that an error is not thrown if
the input stream does not exist.
This capability is extended to the map_channel option.
This allows a ffmpeg command not to break if an input channel does not
exist, which can be of use (for instance, scripts processing audio
channels with sources having unset number of audio channels).

7ce47090ce ffmpeg: Support setting the hardware device to use when filtering
This only supports one device globally, but more can be used by
passing them with input streams in hw_frames_ctx or by deriving new
devices inside a filter graph with hwmap.
