Here's the output of vlc --longhelp --advanced --help-verbose of the version 0.8.6i in Windows.
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 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 Help options -h, --help print help for VLC (can be combined with --advanced) -H, --longhelp print help for VLC and all its modules (can be combined with --advanced) --advanced print help for the advanced options --help-verbose ask for extra verbosity when displaying help -l, --list print a list of available modules -p, --module <string> print help on a specific module (can be combined with --advanced) --save-config save the current command line options in the config --reset-config reset the current config to the default values --config <string> use alternate config file --reset-plugins-cache resets the current plugins cache --version print version information Audio --audio, --no-audio Enable audio (default enabled) You can completely disable the audio output.

(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-filter <string> Audio filters This adds audio post processing filters, to modify the sound rendering. --audio-visual <string> Audio visualizations This adds visualization modules (spectrum analyzer, etc.). Video -f, --fullscreen, --no-fullscreen Fullscreen video output (default disabled) Start video in fullscreen mode (default disabled) --overlay, --no-overlay Overlay video output (default disabled) Overlay is the hardware acceleration capability of your video card (ability to render video directly).

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. --custom-aspect-ratios <string> Custom aspect ratios list Comma seperated list of aspect ratios which will be added in the interface's aspect ratio list. --vout-filter <string> Video filter module This adds post-processing filters to enhance the picture quality, for instance deinterlacing, or to clone or distort the video window.

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.

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 0 to 51. --sout-x264-qpmin <integer> Min QP Minimum quantizer parameter. 15 to 35 seems to be a useful range. --sout-x264-qpmax <integer> Max QP Maximum quantizer parameter. --sout-x264-qpstep <integer> Max QP step Max QP step between frames. --sout-x264-ratetol <float> Average bitrate tolerance Allowed variance in average bitrate (in kbits/s). --sout-x264-vbv-maxrate <integer> Max local bitrate Sets a maximum local bitrate (in kbits/s). --sout-x264-vbv-bufsize <integer> VBV buffer Averaging period for the maximum local bitrate (in kbits). --sout-x264-vbv-init <float> Initial VBV buffer occupancy Sets the initial buffer occupancy as a fraction of the buffer size.
