Function Documentation

display()

std::shared_ptr< display_t > platf::display	(	platf::mem_type_e	hwdevice_type,
		const std::string &	display_name,
		const video::config_t &	config )

Get the display_t instance for the given hwdevice_type. If display_name is empty, use the first monitor that's compatible you can find If you require to use this parameter in a separate thread, make a copy of it.

Parameters

display_name	The name of the monitor that SHOULD be displayed
config	Stream configuration

Returns

The display_t instance based on hwdevice_type.

Pick a display adapter and capture method.

Parameters

hwdevice_type

enables possible use of hardware encoder

display_names()

std::vector< std::string > platf::display_names

(

mem_type_e

hwdevice_type

)

List display names accepted by the selected capture backend.

Parameters

hwdevice_type

Hardware device type requested for capture or encode.

Returns

Display names accepted by the selected capture backend.

needs_encoder_reenumeration()

bool platf::needs_encoder_reenumeration

(

)

Check if GPUs/drivers have changed since the last call to this function.

Check whether DXGI reports that adapter or driver enumeration is stale.

Report whether encoder backends should be probed again before streaming.

Returns

true if a change has occurred or if it is unknown whether a change occurred.

Always true because Linux GPU changes are not tracked by this backend.

Always true because macOS GPU changes are not tracked by this backend.
