◆ ~Hardware()

virtual ~Hardware ( )

protectedvirtual

This object can be destroyed only by the library.

The caller must use Reference::release.

Member Function Documentation

◆ devices()

virtual HwDeviceList * devices ( )

pure virtual

Returns an immutable list of devices that support hardware-accelerated encoding, decoding or processing.

Returns: A list of Device objects. The device list canont be NULL. It is initially empty when the Hardware object is created. It is populated after a call to the refresh() method.

The returned list exists only in the context of Hardware.

◆ refresh()

virtual void refresh ( HwVendor::Enum vendor = HwVendor::None )

pure virtual

Scans the system for available hardware codecs and populates the device list.

Parameters

vendor [in] Vendor filter. Only devices that match the specified vendor are queried. By default vendor is HwVendor::None which queries all known devices on the system.
