VK_KHR_video_encode_queue(3) Manual Page

5

This extension builds upon the VK_KHR_video_queue extension by adding common APIs specific to video encoding and thus enabling implementations to expose queue families supporting video encode operations.

More specifically, it adds video encode specific capabilities and a new command buffer command that allows recording video encode operations against a video session.

This extension is to be used in conjunction with other codec specific video encode extensions that enable encoding video sequences of specific video compression standards.

If VK_KHR_format_feature_flags2 is supported:

1) Why is there no VK_PIPELINE_STAGE_VIDEO_ENCODE_BIT_KHR?

RESOLVED: This extension requires VK_KHR_synchronization2 because the new access flags introduced did not fit in the 32-bit enum VkAccessFlagBits. Accordingly, all new pipeline stage and access flags have been added to the corresponding 64-bit enum and no new flags have been added to the legacy 32-bit enums. While the new pipeline stage flag introduced uses bit #27 which would also fit in the legacy VkPipelineStageFlagBits enum, there is no real benefit to include it. Instead the bit is marked reserved.
