        lifted if a SSH tunnel can be deduced (but -localhost still
        applies).

+     * The [75]-sslverify option allows for authenticating VNC clients
        via their certificates in either -ssl or -stunnel modes.
      * An SSL enabled Java applet VNC Viewer applet is provided in
        classes/ssl/VncViewer.jar. It may also be loaded into the web
        browser via https (http over SSL) in addition to http. (via the
-       VNC port or also by the separate [75]-https port option).
-     * The [76]-usepw option will try to use your existing ~/.vnc/passwd
+       VNC port or also by the separate [76]-https port option). A
+       wrapper shell script [77]ssl_vncviewer is also provided that sets
+       up a stunnel client-side tunnel on Unix systems.
+     * The [78]-usepw option will try to use your existing ~/.vnc/passwd
        or ~/.vnc/passwfile passwords or otherwise prompt you to create
        one (the server exits unless a password file is found and used).
+     * Improved support for Webcams and TV tuner devices (/dev/video)
+       with the [79]-rawfb option. E.g. "-rawfb video0" will autodetect
+       the video WxHxB (requires Video4Linux buildtime or the v4l-info

+       console (/dev/fb0) and inject keystrokes into it (/dev/ttyX). Like
+       LinuxVNC or -pipeinput vcinject.pl, but now built in.
+     * The [81]-24to32 option provides automatic translation from 24bpp
+       to 32bpp framebuffers to avoid problems with viewers, etc (often
+       needed for webcams).
      * The X CLIPBOARD selection is now managed in addition to PRIMARY.

+
+   Yes, this is possible to some degree with the [532]-rawfb option.
+   There is no X11 involved: snapshots from the video capture device are
+   used for the screen image data. See the [533]previous FAQ on -rawfb
+   for background. For best results, use x11vnc version 0.8.1 or later.
+
+   Roughly, one would do something like this:
+  x11vnc -rawfb snap:/dev/video@320x240x32
+
+   This requires that the system allows simple read(2) access to the
+   video device. This is true for video4Linux on Linux kernel 2.6 and
+   later (it won't work for 2.4, you'll need a separate program to
+   snapshot to a file that you point -rawfb to; ask me if it is not clear
+   what to do).
+
+   The "snap:" enforces [534]-snapfb mode which appears to be necessary.
+   The read pointer for video capture devices cannot be repositioned
+   (which would be needed for scanline polling), but you can read a full
+   frame of data from the device.
+
+   On Linux, if the Video4Linux API is present or the v4l-info(1) program
+   (related to xawtv) exists in in PATH, then x11vnc can be instructed to
+   try it to determine the -rawfb WxHxB parameters for you automatically.
+   In this case one would just type:
+  x11vnc -rawfb video
+
+   or "-rawfb video1" for the 2nd video device, etc.
+
+   x11vnc has also been extended to use the Video4Linux API over v4l-info
+   if it is available at build time. This enables setting parameters
+   (e.g. size and brightness) via x11vnc. See the description below.
+   Without Video4Linux you will need to initialize the settings of the
+   video device using something like xawtv or spcaview (and then hope the
+   settings persist until x11vnc reopens the device).
+
+   Many video4linux drivers tend to set the framebuffer to be 24bpp (as
+   opposed to 32bpp). Since this can cause problems with VNC viewers,
+   etc, the [535]-24to32 option will be automatically imposed when in
+   24bpp.
+
+   Note that by its very nature, video capture involves rapid change in
+   the framebuffer. This is especially true for cameras where slight
+   wavering in brightness is always happening. This can lead to much
+   network bandwidth consumption for the VNC traffic and also local CPU
+   and I/O resource usage. You may want to experiment with "dialing down"
+   the framerate via the [536]-wait, [537]-slow_fb, or [538]-defer
+   options. Decreasing the window size and bpp also helps.
+
+
+   Setting Camera/Tuner parameters via x11vnc:
+
+   There is also some support for setting parameters of the capture
+   device. This is done via "-rawfb video:<settings>". This could be
+   useful for unattended startup at boottime, etc. Here is the -help
+   description:
+
+     A more sophisticated video device scheme allows initializing the
+     device's settings using:
+
+           -rawfb video:<settings>
+
+     The prefix could also be, as above, e.g. "video1:" to specify the
+     device file. The v4l API must be available for this to work.
+     Otherwise, you will need to try to initialize the device with an
+     external program, e.g. xawtv, spcaview, and hope they persist when
+     x11vnc re-opens the device.
+
+     <settings> is a comma separated list of key=value pairs. The
+     device's brightness, color, contrast, and hue can be set to
+     percentages, e.g. br=80,co=50,cn=44,hu=60.
+
+     The device filename can be set too if needed (if it does not start
+     with "video"), e.g. fn=/dev/qcam.
+
+     The width, height and bpp of the framebuffer can be set via, e.g.,
+     w=160,h=120,bpp=16.
+
+     Related to the bpp above, the pixel format can be set via the
+     fmt=XXX, where XXX can be one of: GREY, HI240, RGB555, RGB565,
+     RGB24, and RGB32 (with bpp 8, 8, 16, 16, 24, and 32 respectively).
+     See http://www.linuxtv.org for more info (V4L api).
+
+     For tv/rf tuner cards one can set the tuning mode via tun=XXX where
+     XXX can be one of PAL, NTSC, SECAM, or AUTO.
+
+     One can switch the input channel by the inp=XXX setting, where XXX
+     is the name of the input channel (Television, Composite1, S-Video,
+     etc). Use the name that is in the information about the device that
+     is printed at startup.
+
+     For input channels with tuners (e.g. Television) one can change
+     which station is selected by the sta=XXX setting. XXX is the
+     station number. Currently only the ntsc-cable-us (US cable)
+     channels are built into x11vnc. See the -freqtab option below to
+     supply one from xawtv. If XXX is greater than 500, then it is
+     interpreted as a raw frequency in KHz.
+
+     Example:
+
+     -rawfb video:br=80,w=320,h=240,fmt=RGB32,tun=NTSC,sta=47
+
+     one might need to add inp=Television too for the input channel to
+     be TV if the card doesn't come up by default in that one.
+
+     Note that not all video capture devices will support all of the
+     above settings.
+
+     See the -pipeinput VID option below for a way to control the
+     settings through the VNC Viewer via keystrokes.
+
+     As above, if you specify a "@WxHxB..." after the <settings> string
+     they are used verbatim: the device is not queried for the current
+     values. Otherwise the device will be queried.
+
+   Also, if you supply the "-pipeinput VID" option you can control the
+   settings to some degree via keystroke mappings, e.g. B to increase the
+   brightness or Up arrow to change the TV station:
+
+     For "-pipeinput VID" and you are using the -rawfb for a video
+     capture device, then an internal list of keyboard mappings is used
+     to set parameters of the video. The mappings are:
+
+         "B" and "b" adjust the brightness up and down.
+         "H" and "h" adjust the hue.

+-24to32                Very rare problem: if the framebuffer (X display

+                       The idea is the WxHxB will be extracted from the
+                       device itself.  So if you do not supply "@WxHxB...
+                       parameters x11vnc will try to determine them.  It first
+                       tries the v4l API if that support has been compiled in.
+                       Otherwise it will run the v4l-info(1) external program
+                       if it is available.
+
+                       The simplest examples are "-rawfb video" and "-rawfb
+                       video1" which imply the device file /dev/video and
+                       /dev/video1, respectively.  You can also supply the
+                       /dev if you like, e.g. "-rawfb /dev/video0"
+
+                       Since the video capture device framebuffer usually
+                       changes continuously (e.g. brightness fluctuations),
+                       you may want to use the -wait, -slow_fb, or -defer
+                       options to lower the "framerate" to cut down on
+                       network VNC traffic.
+
+                       A more sophisticated video device scheme allows
+                       initializing the device's settings using:
+
+                           -rawfb video:<settings>
+
+                       The prefix could also be, as above, e.g. "video1:" to
+                       specify the device file.  The v4l API must be available
+                       for this to work.  Otherwise, you will need to try
+                       to initialize the device with an external program,
+                       e.g. xawtv, spcaview, and hope they persist when x11vnc
+                       re-opens the device.
+
+                       <settings> is a comma separated list of key=value pairs.
+                       The device's brightness, color, contrast, and hue can
+                       be set to percentages, e.g. br=80,co=50,cn=44,hu=60.
+
+                       The device filename can be set too if needed (if it
+                       does not start with "video"), e.g. fn=/dev/qcam.
+
+                       The width, height and bpp of the framebuffer can be
+                       set via, e.g., w=160,h=120,bpp=16.
+
+                       Related to the bpp above, the pixel format can be set
+                       via the fmt=XXX, where XXX can be one of: GREY, HI240,
+                       RGB555, RGB565, RGB24, and RGB32 (with bpp 8, 8, 16, 16,

+
+                       For tv/rf tuner cards one can set the tuning mode
+                       via tun=XXX where XXX can be one of PAL, NTSC, SECAM,
+                       or AUTO.
+
+                       One can switch the input channel by the inp=XXX setting,
+                       where XXX is the name of the input channel (Television,
+                       Composite1, S-Video, etc).  Use the name that is in the
+                       information about the device that is printed at startup.
+
+                       For input channels with tuners (e.g. Television) one
+                       can change which station is selected by the sta=XXX
+                       setting.  XXX is the station number.  Currently only
+                       the ntsc-cable-us (US cable) channels are built into
+                       x11vnc.  See the -freqtab option below to supply one
+                       from xawtv. If XXX is greater than 500, then it is
+                       interpreted as a raw frequency in KHz.
+
+                       Example:
+
+                       -rawfb video:br=80,w=320,h=240,fmt=RGB32,tun=NTSC,sta=47
+
+                       one might need to add inp=Television too for the input
+                       channel to be TV if the card doesn't come up by default
+                       in that one.
+
+                       Note that not all video capture devices will support
+                       all of the above settings.
+
+                       See the -pipeinput VID option below for a way to control
+                       the settings through the VNC Viewer via keystrokes.
+
+                       As above, if you specify a "@WxHxB..." after the
+                       <settings> string they are used verbatim: the device
+                       is not queried for the current values.  Otherwise the
+                       device will be queried.

+                       because it will be faster and more accurate for Linux
+                       text console.
+
+                       If the rawfb string begins with "cons" the framebuffer
+                       device /dev/fb0 is opened (this requires the appropriate
+                       kernel modules) and so is /dev/tty0.  The latter is
+                       used to inject keystrokes (not all are supported,
+                       but the basic ones are).  You will need to be root to
+                       inject keystrokes.  /dev/tty0 refers to the active VT,
+                       to indicate one explicitly, use "cons2", etc. using
+                       the VT number.  Note you can change VT remotely using
+                       the chvt(1) command.  Sometimes switching out and back
+                       corrects the framebuffer.  To skip injecting entirely
+                       use "consx".
+
+                       The strings "console", or "/dev/fb0" can be used
+                       instead of "cons".  The latter can be used to specify

+Very rare problem: if the framebuffer (X display

+If you DO NOT want x11vnc to close the X DISPLAY in

+Keeping the display open enables the default

+Alternatively, if you specify \fB-noviewonly,\fR then the

+If the device is not "seekable" try reading it all
+at once in full snaps via the "snap:" mode (note:
+this is a resource hog).  If you are using file: or
+map: and the device needs to be reopened for *every*
+snapfb snapshot, set the environment variable:
+SNAPFB_RAWFB_RESET=1 as well.
+.IP
+If you want x11vnc to dynamically transform a 24bpp
+rawfb to 32bpp (note that this will be slower) use
+the \fB-24to32\fR option.  This would be useful for, say,
+for a video camera that delivers the pixel data as
+24bpp packed RGB.  This is the default under "video"
+mode if the bpp is 24.
+.IP
+video4linux: on Linux some attempt is made to handle
+video devices (webcams or tv tuners) automatically.
+The idea is the WxHxB will be extracted from the
+device itself.  So if you do not supply "@WxHxB...
+parameters x11vnc will try to determine them.  It first
+tries the v4l API if that support has been compiled in.
+Otherwise it will run the v4l-
+.IR info (1)
+external program
+if it is available.
+.IP
+The simplest examples are "\fB-rawfb\fR \fIvideo\fR" and "-rawfb
+video1" which imply the device file /dev/video and
+/dev/video1, respectively.  You can also supply the
+/dev if you like, e.g. "\fB-rawfb\fR \fI/dev/video0\fR"
+.IP
+Since the video capture device framebuffer usually
+changes continuously (e.g. brightness fluctuations),
+you may want to use the \fB-wait,\fR \fB-slow_fb,\fR or \fB-defer\fR
+options to lower the "framerate" to cut down on
+network VNC traffic.
+.IP
+A more sophisticated video device scheme allows
+initializing the device's settings using:
+.IP
+\fB-rawfb\fR video:<settings>
+.IP
+The prefix could also be, as above, e.g. "video1:" to
+specify the device file.  The v4l API must be available
+for this to work.  Otherwise, you will need to try
+to initialize the device with an external program,
+e.g. xawtv, spcaview, and hope they persist when x11vnc
+re-opens the device.
+.IP
+<settings> is a comma separated list of key=value pairs.
+The device's brightness, color, contrast, and hue can
+be set to percentages, e.g. br=80,co=50,cn=44,hu=60.
+.IP
+The device filename can be set too if needed (if it
+does not start with "video"), e.g. fn=/dev/qcam.
+.IP
+The width, height and bpp of the framebuffer can be
+set via, e.g., w=160,h=120,bpp=16.
+.IP
+Related to the bpp above, the pixel format can be set
+via the fmt=XXX, where XXX can be one of: GREY, HI240,
+RGB555, RGB565, RGB24, and RGB32 (with bpp 8, 8, 16, 16,
+24, and 32 respectively).  See http://www.linuxtv.org
+for more info (V4L api).
+.IP
+For tv/rf tuner cards one can set the tuning mode
+via tun=XXX where XXX can be one of PAL, NTSC, SECAM,
+or AUTO.
+.IP
+One can switch the input channel by the inp=XXX setting,
+where XXX is the name of the input channel (Television,
+Composite1, S-Video, etc).  Use the name that is in the
+information about the device that is printed at startup.
+.IP
+For input channels with tuners (e.g. Television) one
+can change which station is selected by the sta=XXX
+setting.  XXX is the station number.  Currently only
+the ntsc-cable-us (US cable) channels are built into
+x11vnc.  See the \fB-freqtab\fR option below to supply one
+from xawtv. If XXX is greater than 500, then it is
+interpreted as a raw frequency in KHz.
+.IP
+Example:
+.IP
+\fB-rawfb\fR video:br=80,w=320,h=240,fmt=RGB32,tun=NTSC,sta=47
+.IP
+one might need to add inp=Television too for the input
+channel to be TV if the card doesn't come up by default
+in that one.
+.IP
+Note that not all video capture devices will support
+all of the above settings.
+.IP
+See the \fB-pipeinput\fR VID option below for a way to control
+the settings through the VNC Viewer via keystrokes.
+.IP
+As above, if you specify a "@WxHxB..." after the
+<settings> string they are used verbatim: the device
+is not queried for the current values.  Otherwise the
+device will be queried.
+.IP
+Linux console:  If the libvncserver LinuxVNC command is
+on your system use that instead of the following method
+because it will be faster and more accurate for Linux
+text console.
+.IP
+If the rawfb string begins with "cons" the framebuffer
+device /dev/fb0 is opened (this requires the appropriate
+kernel modules) and so is /dev/tty0.  The latter is
+used to inject keystrokes (not all are supported,
+but the basic ones are).  You will need to be root to
+inject keystrokes.  /dev/tty0 refers to the active VT,
+to indicate one explicitly, use "cons2", etc. using
+the VT number.  Note you can change VT remotely using
+the 
+.IR chvt (1)
+command.  Sometimes switching out and back
+corrects the framebuffer.  To skip injecting entirely
+use "consx".
+.IP
+The strings "console", or "/dev/fb0" can be used
+instead of "cons".  The latter can be used to specify
+a different framebuffer device, e.g. /dev/fb1.  If the
+name is something nonstandard, use "cons:/dev/foofb"
+.IP
+If you do not want x11vnc to guess the framebuffer's
+WxHxB and masks automatically, specify them with a
+@WxHxB at the end of the string.
