VLC-0-9-x command-line help
- 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 -H of the stable 0.9.8a in Windows. If you are looking for 0.8.6 help, go VLC-0-8-6_command-line_help.
Part 1/2
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.
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

vlc://pause:<seconds> Special item to pause the playlist for a certain time
vlc://quit Special item to quit VLC
Audio
These options allow you to modify the behavior of the audio subsystem, and to add audio filters which can be used for post processing or visual effects (spectrum analyzer, etc.). Enable these filters here, and configure them in the "audio filters" modules section.

You can completely disable the audio output. The audio decoding stage
will not take place, thus saving some processing power. (default
enabled)
--volume=<integer [0 .. 1024]>

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, turning on this option might
enhance your experience, especially when combined with the Headphone
Channel Mixer.

--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 [-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-pre-scenecut, --no-sout-x264-pre-scenecut

decision quality
This parameter controls quality versus speed tradeoffs involved in
the motion estimation decision process (lower = quicker and higher =
better quality). Range 1 to 9.

--sout-x264-trellis=<integer [0 .. 2]>
Trellis RD quantization
Trellis RD quantization:
- 0: disabled
- 1: enabled only on the
final encode of a MB
- 2: enabled on all mode decisions
This
requires CABAC.

Early SKIP detection on P-frames (default
enabled)
Early SKIP detection on P-frames. (default enabled)

only a small single coefficient. (default enabled)
--sout-x264-nr=<integer [0 .. 1000]>
Noise reduction
Dct-domain noise reduction. Adaptive pseudo-deadzone. 10 to 1000
seems to be a useful range.
