@item list_devices
If set to @option{true}, print a list of devices and exit.
-Defaults to @option{false}. Alternatively you can use the @code{-sources}
-option of ffmpeg to list the available input devices.
+Defaults to @option{false}. This option is deprecated, please use the
+@code{-sources} option of ffmpeg to list the available input devices.
@item list_formats
If set to @option{true}, print a list of supported formats and exit.
Default behavior is autodetection of the input video format, if the hardware
supports it.
-@item bm_v210
-This is a deprecated option, you can use @option{raw_format} instead.
-If set to @samp{1}, video is captured in 10 bit v210 instead
-of uyvy422. Not all Blackmagic devices support this option.
-
@item raw_format
Set the pixel format of the captured video.
Available values are:
@table @samp
+@item auto
+
+This is the default which means 8-bit YUV 422 or 8-bit ARGB if format
+autodetection is used, 8-bit YUV 422 otherwise.
+
@item uyvy422
+8-bit YUV 422.
+
@item yuv422p10
+10-bit YUV 422.
+
@item argb
+8-bit RGB.
+
@item bgra
+8-bit RGB.
+
@item rgb10
+10-bit RGB.

@item timecode_format
Timecode type to include in the frame and video stream metadata. Must be
@samp{none}, @samp{rp188vitc}, @samp{rp188vitc2}, @samp{rp188ltc},
-@samp{rp188any}, @samp{vitc}, @samp{vitc2}, or @samp{serial}. Defaults to
-@samp{none} (not included).
+@samp{rp188hfr}, @samp{rp188any}, @samp{vitc}, @samp{vitc2}, or @samp{serial}.
+Defaults to @samp{none} (not included).
+
+In order to properly support 50/60 fps timecodes, the ordering of the queried
+timecode types for @samp{rp188any} is HFR, VITC1, VITC2 and LTC for >30 fps
+content. Note that this is slightly different to the ordering used by the
+DeckLink API, which is HFR, VITC1, LTC, VITC2.
@item video_input
Sets the video input source. Must be @samp{unset}, @samp{sdi}, @samp{hdmi},
Option @var{timecode_format} must be specified.
Defaults to @option{false}.
+@item enable_klv(@emph{bool})
+If set to @option{true}, extracts KLV data from VANC and outputs KLV packets.
+KLV VANC packets are joined based on MID and PSC fields and aggregated into
+one KLV packet.
+Defaults to @option{false}.

-Pixel format of the framebuffer. Defaults to @option{bgr0}.
+Pixel format of the framebuffer. This can be autodetected if you are running Linux 5.7

+which is the most common format used by the Linux console and Xorg X server.
@item format_modifier
Format modifier to signal on output frames. This is necessary to import correctly into

@subsection Options
@table @option
+@item select_region
+Specify whether to select the grabbing area graphically using the pointer.
+A value of @code{1} prompts the user to select the grabbing area graphically
+by clicking and dragging. A single click with no dragging will select the
+whole screen. A region with zero width or height will also select the whole
+screen. This option overwrites the @var{video_size}, @var{grab_x}, and
+@var{grab_y} options. Default value is @code{0}.
+
@item draw_mouse
Specify whether to draw the mouse pointer. A value of @code{0} specifies
not to draw the pointer. Default value is @code{1}.

@end example
+@item window_id
+Grab this window, instead of the whole screen. Default value is 0, which maps to
+the whole screen (root window).
+
+The id of a window can be found using the @command{xwininfo} program, possibly with options -tree and
+-root.
+
+If the window is later enlarged, the new area is not recorded. Video ends when
+the window is closed, unmapped (i.e., iconified) or shrunk beyond the video
+size (which defaults to the initial window size).
+
+This option disables options @option{follow_mouse} and @option{select_region}.

@item video_size
-Set the video frame size. Default is the full desktop.
+Set the video frame size. Default is the full desktop or window.
