As you may have noticed, the command vlc --help is not very useful due to to the non-scrollable pop-up window that opened.

If you look for help, on a particular module, use vlc -p module --advanced

So here's the output of vlc --longhelp --advanced --help-verbose for the 0.8.5-test1 (2006/03/27) version in Windows.

     
Usage: vlc.exe [options] [playlistitems] ...
You can specify multiple playlistitems 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 playlistitem directly before it
            and that overrides previous settings.

Playlistitem 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://]filename              Plain media file
  http://ip:port/file            HTTP URL
  ftp://ip:port/file             FTP URL
  mms://ip:port/file             MMS URL
  screen://                      Screen capture
  [dvd://][device][@raw_device]  DVD device
  [vcd://][device]               VCD device
  [cdda://][device]              Audio CD device
  udp:[[<source address>]@[<bind address>][:<bind port>]]
                                 UDP stream sent by a streaming server
  vlc:pause:<seconds>            Special item to pause the playlist for a certain time
  vlc:quit                       Special item to quit VLC

 Audio
      --audio, --no-audio        Enable audio (default enabled)
          You can completely disable the audio output.
          In this case, the audio decoding stage will
          not take place, thus saving some processing
          power. (default enabled)
      --volume <integer>         Default audio volume
          You can set the default audio output volume
          here, in a range from 0 to 1024.

                                 (default disabled)
          This option allows you to use the S/PDIF
          audio output by default when your hardware
          supports it as well as the audio stream being
          played. (default disabled)
      --force-dolby-surround {0 (Auto), 1 (On), 2 (Off)}
                                 Force detection of Dolby Surround
          Use this when you know your stream is (or is
          not) encoded with Dolby Surround but fails to
          be detected as such. And even if the stream
          is not actually encoded with Dolby Surround,
          turning on this option might enhance your
          experience, especially when combined with the
          Headphone Channel Mixer.
      --audio-filter <string>    Audio filters
          This allows you to add audio post processing
          filters, to modify the sound
      --audio-visual <string>    Audio visualizations 
          This allows you to add visualization modules
          (spectrum analyzer, etc.).

 Video
  -f, --fullscreen, --no-fullscreen
                                 Fullscreen video output (default disabled)
          If this option is enabled, VLC will always
          start a video in fullscreen mode. (default
          disabled)
      --overlay, --no-overlay    Overlay video output (default enabled)
          If enabled, VLC will try to take advantage of
          the overlay capabilities of your graphics
          card (hardware acceleration). (default
          enabled)
      --video-on-top, --no-video-on-top
                                 Always on top (default disabled)
          Always place the video window on top of other
          windows. (default disabled)
      --snapshot-path <string>   Video snapshot directory
          Allows you to specify the directory where the
          video snapshots will be stored.
      --snapshot-format {png,jpg}
                                 Video snapshot format

      --snapshot-preview, --no-snapshot-preview
                                 Display video snapshot preview (default
                                 enabled)

          preview in the screen's to  left corner.
          (default enabled)
      --crop <string>            Video cropping
          This will force the cropping of the source
          video. Accepted formats are x:y (4:3, 16:9,
          etc.) expressing the global image aspect.
      --aspect-ratio <string>    Source aspect ratio
          This will force the source aspect ratio. For
          instance, some DVDs claim to be 16:9 while
          they are actually 4:3. This can also be used
          as a hint for VLC when a movie does not have
          aspect ratio information. Accepted formats
          are x:y (4:3, 16:9, etc.) expressing the
          global image aspect, or a float value (1.25,
          1.3333, etc.) expressing pixel squareness.
      --vout-filter <string>     Video filter module
          This will allow you to add a post-processing
          filter to enhance the picture quality, for

          subtitle filename is specified. (default
          enabled)
      --sub-filter <string>      Subpictures filter module
          This will allow you to add a subpictures
          filter for instance to overlay a logo.
      --audio-language <string>  Audio language
          Give the language of the audio track you want
          to use (comma separted, two or three letter

          Increasing the priority of the process will
          very likely improve your playing experience
          as it allows VLC not to be disturbed by other
          applications that could otherwise take too
          much processor time. However be advised that
          in certain circumstances (bugs) VLC could
          take all the processor time and render the

 H.264/MPEG4 AVC encoder (using x264 library)
      --sout-x264-keyint <integer>
                                 Maximum GOP size
          Sets maximum interval between
          IDR-frames.Larger values save bits, thus
          improve quality for a given bitrate at the
          cost of seeking precision.
      --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
          frameref). 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-scenecut <integer>
                                 How aggressively to insert extra I-frames (-1
                                 to 100)
          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 be inserted only
          every other keyint frames, which probably
          leads to ugly encoding artifacts.
      --sout-x264-bframes <integer>
                                 Number of B-frames between I and P (1 to 16)

          If this is on, the specified number of
          consecutive B-frames will always be used,
          except possibly before an I-frame.  (default
          enabled)
      --sout-x264-b-bias <integer>
                                 Influences how often B-frames are used
          Bias the choice to use B-frames. Positive
          values cause more B-frames, negative values
          cause less B-frames. 
      --sout-x264-bpyramid, --no-sout-x264-bpyramid
                                 Keep some B-frames as references (default
                                 disabled)
          Allows B-frames to be used as references for
          predicting other frames. Keeps the middle of
          2+ consecutive B-frames as a reference, and
          reorders frame appropriately. (default
          disabled)

          material. Some decoders are unable to deal
          with large frameref values.
