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)
 
          Enable hacks for Blu-ray support, this doesn't enforce every aspect
 
          of Blu-ray compatibility e.g. resolution, framerate, level
 
      --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]>

                                Keep some B-frames as references
 
          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.  - none: Disabled  - strict: Strictly

          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-qsv-idr-interval=<integer>
 
                                IDR interval
 
          For H.264, IdrInterval specifies IDR-frame interval in terms of
 
          I-frames; if IdrInterval=0, then every I-frame is an IDR-frame. If
 
          IdrInterval=1, then every other I-frame is an IDR-frame, etc. For
 
          MPEG2, IdrInterval defines sequence header interval in terms of
 
          I-frames. If IdrInterval=N, SDK inserts the sequence header before
 
          every Nth I-frame. If IdrInterval=0 (default), SDK inserts the
 
          sequence header once at the beginning of the stream.

          synchronise the result. Higher numbers may result on better
 
          throughput depending on hardware. MPEG2 needs at least 1 here.
 
 
 
Kate overlay decoder (kate)
 
Kate is a codec for text and image based overlays.
 
The Tiger rendering library is needed to render complex Kate streams, but VLC can still render static text and image based subtitles if it is not available.
 
Note that changing settings below will not take effect until a new stream is played. This will hopefully be fixed soon.
 
      --kate-formatted, --no-kate-formatted
 
                                Formatted Subtitles
 
                                (default enabled)
 
          Kate streams allow for text formatting. VLC partly implements this,
 
          but you can choose to disable all formatting. Note that this has no
 
          effect is rendering via Tiger is enabled.

                                (default disabled)
 
          Save the raw codec data if you have selected/forced the dummy decoder
 
          in the main options.
 
 
 
DTS Coherent Acoustics audio decoder (dca)
 
      --dts-dynrng, --no-dts-dynrng
 
                                DTS 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.
 
 
 
Closed Captions decoder (cc)
 
      --cc-opaque, --no-cc-opaque
 
                                Opacity
 
                                (default enabled)
 
          Setting to true makes the text to be boxed and maybe easier to read.

      --avcodec-error-resilience=<integer>
 
                                Error resilience
 
          libavcodec can do error resilience. However, with a buggy encoder
 
          (such as the ISO MPEG-4 encoder from M$) this can produce a lot of
 
          errors. Valid values range from 0 to 4 (0 disables all errors
 
          resilience).
 
      --avcodec-workaround-bugs=<integer>
 
                                Workaround bugs
 
          Try to fix some bugs: 1  autodetect 2  old msmpeg4 4  xvid interlaced
 
          8  ump4  16 no padding 32 ac vlc 64 Qpel chroma. This must be the sum
 
          of the values. For example, to fix "ac vlc" and "ump4", enter 40.
 
      --avcodec-hurry-up, --no-avcodec-hurry-up
 
                                Hurry up
 
                                (default enabled)
 
          The decoder can partially decode or skip frame(s) when there is not
 
          enough time. It's useful with low CPU power but it can produce
 
          distorted pictures.
 
      --avcodec-skip-frame={-1 (None), 0 (Default), 1 (Non-ref), 2 (Bidir), 3 (Non-key), 4 (All)}
 
                                Skip frame (default=0)
 
          Force skipping of frames to speed up decoding (-1=None, 0=Default,
 
          1=B-frames, 2=P-frames, 3=B+P frames, 4=all frames).
 
      --avcodec-skip-idct=<integer [-1 .. 4]>
 
                                Skip idct (default=0)
 
          Force skipping of idct to speed up decoding for frame types (-1=None,

          error-prone.
 
      --avcodec-skiploopfilter={0 (None), 1 (Non-ref), 2 (Bidir), 3 (Non-key), 4 (All)}
 
                                Skip the loop filter for H.264 decoding
 
          Skipping the loop filter (aka deblocking) usually has a detrimental
 
          effect on quality. However it provides a big speedup for high
 
          definition streams.

                                (default disabled)
 
          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.

          for example if you associated VLC with some media types and you don't
 
          want a new instance of VLC to be opened each time you open a file in
 
          your file manager. This option will allow you to play the file with
 
          the already running instance or enqueue it.

See also Command-line interface, Console interfaces

Windows

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

To view this without leaving the command-line, use the following command (assuming you installed it in the default folder):

more "C:\Program Files\VideoLAN\VLC\vlc-help.txt"

This trick uses the command-line pager 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:
