Detailed Description

Definitions for Wayland capture.

Macro Definition Documentation

CLASS_CALL

#define CLASS_CALL	(		c,
			m )

Value:

classCall<c, decltype(&c::m), &c::m>

Macro for CLASS CALL.

Function Documentation

export_gbm_bo_planes()

std::optional< std::uint32_t > wl::export_gbm_bo_planes	(	gbm_bo *	bo,
		frame_t &	frame,
		const gbm_bo_accessors_t &	accessors )

Export every GBM buffer plane into a captured frame descriptor.

Parameters

bo	GBM buffer whose DMA-BUF planes will be exported.
frame	Frame that takes ownership of the exported file descriptors.
accessors	GBM accessors used to query the buffer.

Returns

Number of exported planes, or no value when the buffer cannot be exported.

init()

int wl::init

(

)

Initialize Wayland registry interfaces required for capture.

Returns

0 on success; nonzero or negative platform status on failure.

intersect_modifiers()

std::map< std::uint32_t, std::vector< std::uint64_t > > wl::intersect_modifiers	(	const std::map< std::uint32_t, std::vector< std::uint64_t > > &	compositor_modifiers,
		const std::map< std::uint32_t, std::vector< std::uint64_t > > &	encoder_modifiers )

Intersect compositor and encoder modifiers to find common formats.

Parameters

compositor_modifiers	Modifiers supported by the compositor for each format.
encoder_modifiers	Modifiers supported by the encoder for each format.

Returns

Intersection of formats and modifiers supported by both.

monitors()

std::vector< std::unique_ptr< monitor_t > > wl::monitors

(

const char *

display_name = nullptr

)

Refresh the monitor list reported by the display server.

Parameters

display_name

Display name.

Returns

Monitors reported by the Wayland compositor, optionally filtered by name.
