Description
This extension builds upon the VK_KHR_video_queue
extension by
adding common APIs specific to video decoding and thus enabling
implementations to expose queue families supporting video decode operations.
More specifically, it adds video decode specific capabilities and a new command buffer command that allows recording video decode operations against a video session.
This extension is to be used in conjunction with other codec specific video decode extensions that enable decoding video sequences of specific video compression standards.
