color_vulkan

Video source that creates a Vulkan frame of a solid color. Useful for benchmarking, or overlaying.

It accepts the following parameters:

color

The color to use. Either a name, or a hexadecimal value. The default value is black.

size

The size of the output frame. Default value is 1920x1080.

rate

The framerate to output at. Default value is 60 frames per second.

duration

The video duration. Default value is -0.000001.

sar

The video signal aspect ratio. Default value is 1/1.

format

The pixel format of the output Vulkan frames. Default value is yuv444p.

out_range

Set the output YCbCr sample range.

This allows the autodetected value to be overridden as well as allows forcing a specific value used for the output and encoder. If not specified, the range depends on the pixel format. Possible values:

‘auto/unknown’

Choose automatically.

‘jpeg/full/pc’

Set full range (0-255 in case of 8-bit luma).

‘mpeg/limited/tv’

Set "MPEG" range (16-235 in case of 8-bit luma).
