@end itemize
@section ddagrab
Captures the Windows Desktop via Desktop Duplication API.
The filter exclusively returns D3D11 Hardware Frames, for on-gpu encoding
or processing. So an explicit @ref{hwdownload} is needed for any kind of
software processing.
It accepts the following options:
@table @option
@item output_idx
DXGI Output Index to capture.
Usually corresponds to the index Windows has given the screen minus one,
so it's starting at 0.
Defaults to output 0.
@item draw_mouse
Whether to draw the mouse cursor.
Defaults to true.
Only affects hardware cursors. If a game or application renders its own cursor,
it'll always be captured.
@item framerate
Framerate at which the desktop will be captured.
Defaults to 30 FPS.
@item video_size
Specify the size of the captured video.
Defaults to the full size of the screen.
Cropped from the bottom/right if smaller than screen size.
@item offset_x
Horizontal offset of the captured video.
@item offset_y
Vertical offset of the captured video.
@end table
@subsection Examples
Capture primary screen and encode using nvenc:
@example
ffmpeg -f lavfi -i ddagrab -c:v h264_nvenc -cq 18 output.mp4
@end example
You can also skip the lavfi device and directly use the filter.
Also demonstrates downloading the frame and encoding with libx264.
Explicit output format specification is required in this case:
@example
ffmpeg -filter_complex ddagrab=output_idx=1:framerate=60,hwdownload,format=bgra -c:v libx264 -crf 18 output.mp4
@end example
If you want to capture only a subsection of the desktop, this can be achieved
by specifying a smaller size and its offsets into the screen:
@example
ddagrab=video_size=800x600:offset_x=100:offset_y=100
@end example
@section gradients
Generate several gradients.
