KMS video input device.

|
||||
Captures the KMS scanout framebuffer associated with a specified CRTC or plane as a
|
||||
DRM object that can be passed to other hardware functions.
|
||||
|
||||
Requires either DRM master or CAP_SYS_ADMIN to run.

@option{x11grab} instead.

@subsection Options
|
||||
|
||||
@table @option
|
||||
|
||||
@item device
|
||||
DRM device to capture on. Defaults to @option{/dev/dri/card0}.
|
||||
|
||||
@item format
|
||||
Pixel format of the framebuffer. Defaults to @option{bgr0}.
|
||||
|
||||
@item format_modifier
|
||||
Format modifier to signal on output frames. This is necessary to import correctly into
|
||||
some APIs, but can't be autodetected. See the libdrm documentation for possible values.
|
||||
|
||||
@item crtc_id
|
||||
KMS CRTC ID to define the capture source. The first active plane on the given CRTC
|
||||
will be used.
|
||||
|
||||
@item plane_id
|
||||
KMS plane ID to define the capture source. Defaults to the first active plane found if
|
||||
neither @option{crtc_id} nor @option{plane_id} are specified.
|
||||
|
||||
@item framerate
|
||||
Framerate to capture at. This is not synchronised to any page flipping or framebuffer
|
||||
changes - it just defines the interval at which the framebuffer is sampled. Sampling
|
||||
faster than the framebuffer update rate will generate independent frames with the same
|
||||
content. Defaults to @code{30}.

@subsection Examples

@itemize

@item
|
||||
Capture from the first active plane, download the result to normal frames and encode.
|
||||
This will only work if the framebuffer is both linear and mappable - if not, the result
|
||||
may be scrambled or fail to download.
|
||||
@example
|
||||
ffmpeg -f kmsgrab -i - -vf 'hwdownload,format=bgr0' output.mp4

@end example
|
||||
|
||||
@item
|
||||
Capture from CRTC ID 42 at 60fps, map the result to VAAPI, convert to NV12 and encode as H.264.
|
||||
@example
|
||||
ffmpeg -crtc_id 42 -framerate 60 -f kmsgrab -i - -vf 'hwmap=derive_device=vaapi,scale_vaapi=w=1920:h=1080:format=nv12' -c:v h264_vaapi output.mp4

@section libndi_newtek
|
||||
|
||||
The libndi_newtek input device provides capture capabilities for using NDI (Network
|
||||
Device Interface, standard created by NewTek).
|
||||
|
||||
Input filename is a NDI source name that could be found by sending -find_sources 1
|
||||
to command line - it has no specific syntax but human-readable formatted.
|
||||
|
||||
To enable this input device, you need the NDI SDK and you
|
||||
need to configure with the appropriate @code{--extra-cflags}
|
||||
and @code{--extra-ldflags}.

@item wait_sources

Override time to wait until the number of online sources have changed.
|
||||
Defaults to @option{0.5}.

@item allow_video_fields
