Running the command
vlc --help
will create a .TXT file containing all the command-line options.
You can also use this to get more exhaustive list:
vlc -H
If you look for help, on a particular module, you can also use
vlc -p module --advanced --help-verbose
--help-verbose explains things. Omit this option if too much output is generated
To view this without leaving the command-line in Windows, use the following command (assuming you installed it in the default folder):
more "%PROGRAMFILES%\VideoLAN\VLC\vlc-help.txt"
This trick uses the command-line command more to show the file screen-by-screen. Pressing spacebar will advance the output a screen at a time, and pressing enter will advance the output one line at a time.
Undocumented option:
-vv "Verbose verbose". Verbose output (debug infos can be displayed by selecting "Debug logging" interface under View->Add Interface menu)
Here's the output of vlc -H of vlc-4.0.0-dev under Windows. If the text is too small, pressing Ctrl and + together in most browsers will increase the font size (reset with Ctrl and 0 together).
Usage: vlc [options] [stream] ...
You can specify multiple streams on the commandline.
They will be enqueued in the playlist.
The first item specified will be played first.
Options-styles:
--option A global option that is set for the duration of the program.
-option A single letter version of a global --option.
:option An option that only applies to the stream directly before it
and that overrides previous settings.
Stream MRL syntax:
[[access][/demux]://]URL[#[title][:chapter][-[title][:chapter]]]
[:option=value ...]
Many of the global --options can also be used as MRL specific :options.
Multiple :option=value pairs can be specified.
URL syntax:
file:///path/file Plain media file
http://host[:port]/file HTTP URL
ftp://host[:port]/file FTP URL
mms://host[:port]/file MMS URL

Presentation Level
H.264/MPEG-4 Part 10/AVC encoder (x264) (x264)
--sout-x264-keyint=<integer>
Maximum GOP size
Sets maximum interval between IDR-frames. Larger values save bits,
thus improving quality for a given bitrate at the cost of seeking
precision. Use -1 for infinite.
--sout-x264-min-keyint=<integer>
Minimum GOP size
Sets minimum interval between IDR-frames. In H.264, I-frames do not
necessarily bound a closed GOP because it is allowable for a P-frame
to be predicted from more frames than just the one frame before it
(also see reference frame option). Therefore, I-frames are not
necessarily seekable. IDR-frames restrict subsequent P-frames from
referring to any frame prior to the IDR-frame. If scenecuts appear
within this interval, they are still encoded as I-frames, but do not
start a new GOP.
--sout-x264-opengop, --no-sout-x264-opengop
Use recovery points to close GOPs
(default disabled)

--sout-x264-scenecut=<integer [-1 .. 100]>
Extra I-frames aggressivity
Scene-cut detection. Controls how aggressively to insert extra
I-frames. With small values of scenecut, the codec often has to force
an I-frame when it would exceed keyint. Good values of scenecut may
find a better location for the I-frame. Large values use more
I-frames than necessary, thus wasting bits. -1 disables scene-cut
detection, so I-frames are inserted only every other keyint frames,
which probably leads to ugly encoding artifacts. Range 1 to 100.
--sout-x264-bframes=<integer [0 .. 16]>
B-frames between I and P
Number of consecutive B-frames between I and P-frames. Range 1 to 16.

Adaptive B-frame decision
Force the specified number of consecutive B-frames to be used, except
possibly before an I-frame. Range 0 to 2.
--sout-x264-b-bias=<integer [-100 .. 100]>
Influence (bias) B-frames usage
Bias the choice to use B-frames. Positive values cause more B-frames,
