## Description

`VK_KHR_video_maintenance1` adds a collection of minor video coding features, none of which would warrant an entire extension of their own.

The new features are as follows:

- Allow creating buffers that can be used in video coding operations, independent of the used video profile, using the new buffer creation flag `VK_BUFFER_CREATE_VIDEO_PROFILE_INDEPENDENT_BIT_KHR`.

- Allow creating images that can be used as decode output or encode input pictures, independent of the used video profile, using the new image creation flag `VK_IMAGE_CREATE_VIDEO_PROFILE_INDEPENDENT_BIT_KHR`.

- Allow specifying queries used by video coding operations as part of the video coding command parameters, instead of using begin/end query when the video session is created using the new video session creation flag `VK_VIDEO_SESSION_CREATE_INLINE_QUERIES_BIT_KHR`.
