Update: the previously suggested --volume argument no longer works.

In more recent versions of VLC, you may adjust volume manually via commandline parameter:

vlc.exe [file] --gain [value]

The value is documented in --help --advanced to be a float in range of [0.000000 .. 8.000000], but test show that higher, even much higher values are also accepted (tested up to few thousands).

The gain value is independent of volume value, eg. regardless of the gain value and effective volume, the in-application volume will show as 100% or any other preset value.

The argument is as of this moment not defined in the manual.

Example:

vlc.exe %HOMEDIR%\Desktop\movie.flv --gain 16

You may adjust volume manually via commandline parameter:

vlc.exe [file] --volume [value]

The manual claims that the maximum volume value is 1024, yet actually you can put any value. The 256 corresponds to 100%, 512 to 200% and so on. Tried up to 4096 and it worked :)

Example:

vlc.exe %HOMEDIR%\Desktop\movie.flv --volume 2048
