- See also Command line, Console interfaces
As you may have noticed, running the command
vlc --help
on some command prompts 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 development version 0.9.0-svn-20070112-0001 (12 jan. 2007) in Windows.
Usage: vlc.exe [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://]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.
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.
--volume-step=<integer> Audio output volume step
The step size of the volume is adjustable
using this option, in a range from 0 to 1024.
--aout-rate=<integer> Audio output frequency (Hz)
You can force the audio output frequency
here. Common values are -1 (default), 48000,
44100, 32000, 22050, 16000, 11025, 8000.
--hq-resampling, --no-hq-resampling
High quality audio resampling (default
enabled)
This uses a high quality audio resampling
algorithm. High quality audio resampling can
be processor intensive so you can disable it
and a cheaper resampling algorithm will be
used instead. (default enabled)
--spdif, --no-spdif Use S/PDIF when available (default disabled)
S/PDIF can be used 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. 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-desync=<integer> Audio desynchronization compensation
This delays the audio output. The delay must
be given in milliseconds.This can be handy if
you notice a lag between the video and the
audio.

The default behavior is to automatically
select the best method available.

This adds visualization modules (spectrum
analyzer, etc.).

You can completely disable the video output.
The video decoding stage will not take place,
thus saving some processing power. (default
enabled)

Grayscale video output (default disabled)
Output video in grayscale. As the color
information aren't decoded, this can save
some processing power. (default disabled)

This avoids flooding the message log with
debug output from the video output
synchronization mechanism. (default disabled)
--overlay, --no-overlay Overlay video output (default enabled)

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.
--monitor-par=<string> Monitor pixel aspect ratio

should only disable this option if your video
has a non-standard format requiring all 1088
lines. (default enabled)

(developers only)
On Windows 9x/Me you can use a fast but
incorrect condition variables implementation
(more precisely there is a possibility for a

possible to use slower alternatives which are
more robust. Currently you can choose between
implementation 0 (which is the fastest but
slightly incorrect), 1 (default) and 2.

--dvdread-css-method={title,disc,key}
Method used by libdvdcss for decryption
Set the method used by libdvdcss for key
decryption.
title: decrypted title key is
guessed from the encrypted sectors of the
stream. Thus it should work with a file as
well as the DVD device. But it sometimes
takes much time to decrypt a title key and
may even fail. With this method, the key is
only checked at the beginning of each title,
so it won't work if the key changes in the
middle of a title.
disc: the disc key is
first cracked, then all title keys can be
decrypted instantly, which allows us to check
them often.
key: the same as "disc" if you
don't have a file with player keys at
compilation time. If you do, the decryption
of the disc key will be faster with this
method. It is the one that was used by
libcss.
The default method is: key.

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

P-frames. Range 1 to 16.

values cause more B-frames, negative values
cause less B-frames.
--sout-x264-bpyramid, --no-sout-x264-bpyramid

disabled)
Allows B-frames to be used as references for
