Public Types inherited from platf::display_t
using	pull_free_image_cb_t = std::function<bool(std::shared_ptr<img_t> &img_out)>
	Get free image from pool. Calls must be synchronized. Blocks until there is free image in the pool or capture is interrupted.

using	push_captured_image_cb_t = std::function<bool(std::shared_ptr<img_t> &&img, bool frame_captured)>
	Callback for when a new image is ready. When display has a new image ready or a timeout occurs, this callback will be called with the image. If a frame was captured, frame_captured will be true. If a timeout occurred, it will be false.

Member Function Documentation

◆ alloc_img()

std::shared_ptr< platf::img_t > wl::wlr_ram_t::alloc_img ( )

inlineoverridevirtual

platf::capture_e wl::wlr_ram_t::capture	(	const push_captured_image_cb_t &	push_captured_image_cb,
		const pull_free_image_cb_t &	pull_free_image_cb,
		bool *	cursor )

inlineoverridevirtual

Capture a frame.

Parameters

push_captured_image_cb	The callback that is called with captured image, must be called from the same thread as capture()
pull_free_image_cb	Capture backends call this callback to get empty image from the pool. If backend uses multiple threads, calls to this callback must be synchronized. Calls to this callback and push_captured_image_cb must be synchronized as well.
cursor	A pointer to the flag that indicates whether the cursor should be captured as well.

Return values

capture_e::ok	When stopping
capture_e::error	On error
capture_e::reinit	When need of reinitialization

std::unique_ptr< platf::avcodec_encode_device_t > wl::wlr_ram_t::make_avcodec_encode_device ( platf::pix_fmt_e pix_fmt )
