Running the command
vlc --help
will create a .TXT file containing all the command-line options.
If you look for help, on a particular module, you can also use
vlc -p module --advanced
Undocumented option:
-vvv "Verbose 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 the stable 2.0.0 under Windows. If you are looking for 0.8.6 help, go VLC-0-8-6_command-line_help. If you are looking for 0.9.x help, go VLC-0-9-x_command-line_help. If you are looking for 1.0.x help, go VLC-1-0-x_command-line_help. If you are looking for 1.1.x help, go VLC-1-1-x_command-line_help

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.

Part 2/2

--sout-x264-keyint=<integer [-2147483648 .. 2147483647]>
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.
--sout-x264-min-keyint=<integer [-2147483648 .. 2147483647]>
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

--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.

Kate overlay decoder
Kate is a codec for text and image based overlays.
