Option doesn't exist .. hasn't for a few years now.

Discarding all frames is universally supported as it happens in fftools
whereas selective discarding relies on the demuxer.

-vn/-an/-sn/-dn can now be used to block input streams from a file.

Flesh out with details and examples to show quirks and limitations.

Thumbnail example added. Avoid transcoding in older examples.

-benchmark and -benchmark_all now show real, system and user time

Also mention -map in the -vn, -an, and -sn options.

Fixes #7036.

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.

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 ...

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).

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.

(cherry picked from commit 303fadf596)

add a per-stream option for setting the encoder timebase.
the following values are allowed:
0 - for video, use 1/frame_rate, for audio use 1/sample_rate (this is
  the default)
-1 - match the input timebase (when possible)
>0 - set the timebase to provided number
