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:///path/file Plain media file
http://host[:port]/file HTTP URL
ftp://host[:port]/file FTP URL
mms://host[:port]/file MMS URL
screen:// Screen capture
dvd://[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> Pause the playlist for a certain time
vlc://quit Special item to quit VLC
No matching module found. Use --list or --list-verbose to list available modules.
VBI and Teletext decoder
--vbi-page <integer [-2147483648 .. 2147483647]>
Teletext page
Open the indicated Teletext page.Default page is index 100
--vbi-opaque, --no-vbi-opaque
Teletext transparency (default enabled)
Setting vbi-opaque to false makes the boxed text transparent. (default enabled)
--vbi-position {0 (Center), 1 (Left), 2 (Right), 4 (Top), 8 (Bottom), 5 (Top-Left), 6 (Top-Right), 9 (Bottom-Left), 10 (Bottom-Right)}
Teletext alignment
You can enforce the teletext position on the video (0=center, 1=left, 2=right, 4=top, 8=bottom, you can
also use combinations of these values, eg. 6 = top-right).
--vbi-text, --no-vbi-text Teletext text subtitles (default disabled)
Output teletext subtitles as text instead of as RGBA (default disabled)
YUV video output
--yuv-file <string> device, fifo or filename
device, fifo or filename to write yuv frames too.
--yuv-chroma <string> Chroma used
Force use of a specific chroma for output. Default is I420.
--yuv-yuv4mpeg2, --no-yuv-yuv4mpeg2
YUV4MPEG2 header (default disabled) (default disabled)
The YUV4MPEG2 header is compatible with mplayer yuv video output and requires YV12/I420 fourcc. By
default vlc writes the fourcc of the picture frame into the output destination. (default disabled)
H.264/MPEG4 AVC encoder (x264)
--sout-x264-keyint <integer [-2147483648 .. 2147483647]>
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 [-2147483648 .. 2147483647]>
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)
use open GOP, for bluray compatibility use also bluray-compat option (default disabled)
--sout-x264-bluray-compat, --no-sout-x264-bluray-compat
Enable compatibility hacks for Blu-ray support (default disabled)
Enable hacks for Blu-ray support, this doesn't enforce every aspect of Blu-ray compatibility
e.g.
resolution, framerate, level (default disabled)
--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]>
B-frames between I and P
Number of consecutive B-frames between I and P-frames. Range 1 to 16.
--sout-x264-b-adapt <integer [0 .. 2]>
Adaptive B-frame decision
Force the specified number of consecutive B-frames to be used, except possibly before an I-frame.Range
0 to 2.
--sout-x264-b-bias <integer [-100 .. 100]>
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 {none,strict,normal}
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 hierarchical pyramid
- normal: Non-strict (not Blu-ray compatible)
--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 [1 .. 16]>
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-psy-rd <string>
Strength of psychovisual optimization, default is "1.0:0.0"
First parameter controls if RD is on (subme>=6) or off.
Second parameter controls if Trellis is used on
psychovisual optimization, default off
--sout-x264-psy, --no-sout-x264-psy
Use Psy-optimizations (default enabled)
Use all visual optimizations that can worsen both PSNR and SSIM (default enabled)
--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). Set to 0 for letting x264 set level.
--sout-x264-profile {baseline,main,high,high10,high422,high444}
H.264 profile
Specify H.264 profile which limits are enforced over other settings
--sout-x264-interlaced, --no-sout-x264-interlaced
