As you may have noticed, running the command
 vlc --help
on some [[command prompt]]s 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

Undocumented option:
  -vvv     "Verbose verbose verbose". Verbose output

Here's the output of ''vlc --longhelp --advanced --help-verbose'' of the version 0.8.6i in Windows. If you are looking for 0.9.0 help, go [[VLC_command-line_help]].

 Audio
      --audio, --no-audio        Enable audio (default enabled)
          You can completely disable the audio output.
          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.

          Use this when you know your stream is (or is
          not) encoded with Dolby Surround but fails to
          be detected as such. Even if the stream is
          not actually encoded with Dolby Surround,

          Use sequential numbers instead of timestamps
          for snapshot numbering (default disabled)
      --crop <string>            Video cropping
          This forces the cropping of the source video.
          Accepted formats are x:y (4:3, 16:9, etc.)
          expressing the global image aspect.

          This forces 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.

                                 Autodetect subtitle files (default enabled)
          Automatically detect a subtitle file, if no
          subtitle filename is specified (based on the
          filename of the movie). (default enabled)
      --sub-filter <string>      Subpictures filter module
          This adds so-called "subpicture filters".
          These filters overlay some images or text
          over the video (like a logo, arbitraty
          text...).
      --audio-language <string>  Audio language
          Language of the audio track you want to use
          (comma separated, two or three letter country
          code).
      --sub-language <string>    Subtitle language
          Language of the subtitle track you want to
          use (comma separated, two or tree letter
          country code).
      --input-repeat <integer>   Input repetitions
          Number of time the same input will be repeated
      --dvd <string>             DVD device

      --high-priority, --no-high-priority
                                 Increase the priority of the process (default
                                 disabled)
          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
          whole system unresponsive which might require
          a reboot of your machine. (default disabled)

          startup.
      --auto-preparse, --no-auto-preparse
                                 Automatically preparse files (default enabled)

 ATSC A/52 (AC-3) audio decoder
      --a52-dynrng, --no-a52-dynrng
                                 A/52 dynamic range compression (default
                                 enabled)
          Dynamic range compression makes the loud
          sounds softer, and the soft sounds louder, so
          you can more easily listen to the stream in a
          noisy environment without disturbing anyone.
          If you disable the dynamic range compression
          the playback will be more adapted to a movie
          theater or a listening room. (default enabled)

          The encoder can make on-the-fly quality
          tradeoffs if your CPU can't keep up with the
          encoding rate. It will disable trellis
          quantization, then the rate distortion of
          motion vectors (hq), and raise the noise
          reduction threshold to ease the encoder's
          task. (default disabled)

 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
          improving 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
          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-scenecut <integer>
                                 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>
                                 B-frames between I and P
          Number of consecutive B-frames between I and
          P-frames. Range 1 to 16.
      --sout-x264-b-adapt, --no-sout-x264-b-adapt
                                 Adaptive B-frame decision (default enabled)
          Force the specified number of consecutive
          B-frames to be used, except possibly before
          an I-frame. (default enabled)
      --sout-x264-b-bias <integer>
                                 Influence (bias) B-frames usage
          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)
      --sout-x264-cabac, --no-sout-x264-cabac
                                 CABAC (default enabled)
          CABAC (Context-Adaptive Binary Arithmetic
          Coding). Slightly slows down encoding and
          decoding, but should save 10 to 15% bitrate.
          (default enabled)
      --sout-x264-ref <integer>  Number of reference frames
          Number of previous frames used as predictors.
          This is effective in Anime, but seems to make
          little difference in live-action source
          material. Some decoders are unable to deal
          with large frameref values. Range 1 to 16.
      --sout-x264-nf, --no-sout-x264-nf
                                 Skip loop filter (default disabled)
          Deactivate the deblocking loop filter
          (decreases quality). (default disabled)
      --sout-x264-deblock <string>
                                 Loop filter AlphaC0 and Beta parameters
                                 alpha:beta
          Loop filter AlphaC0 and Beta parameters.
          Range -6 to 6 for both alpha and beta
          parameters. -6 means light filter, 6 means
          strong.
      --sout-x264-level <string> H.264 level
          Specify H.264 level (as defined by Annex A of
          the standard). Levels are not enforced; it's
          up to the user to select a level compatible
          with the rest of the encoding options. Range
          1 to 5.1 (10 to 51 is also allowed).
      --sout-x264-interlaced, --no-sout-x264-interlaced
                                 Interlaced mode (default disabled)
          Pure-interlaced mode. (default disabled)
      --sout-x264-qp <integer>   Set QP
          This selects the quantizer to use. Lower
          values result in better fidelity, but higher
          bitrates. 26 is a good default value. Range 0
          (lossless) to 51.
      --sout-x264-crf <integer>  Quality-based VBR
          1-pass Quality-based VBR. Range 0 to 51.
