# VkVideoEncodeUsageFlagBitsKHR(3) Manual Page

## Name

VkVideoEncodeUsageFlagBitsKHR - Video encode usage flags

Loading… please wait.

## C Specification

The following bits can be specified in VkVideoEncodeUsageInfoKHR::`videoUsageHints` as a hint about the video encode use case:

    // Provided by VK_KHR_video_encode_queue
    typedef enum VkVideoEncodeUsageFlagBitsKHR {
        VK_VIDEO_ENCODE_USAGE_DEFAULT_KHR = 0,
        VK_VIDEO_ENCODE_USAGE_TRANSCODING_BIT_KHR = 0x00000001,
        VK_VIDEO_ENCODE_USAGE_STREAMING_BIT_KHR = 0x00000002,
        VK_VIDEO_ENCODE_USAGE_RECORDING_BIT_KHR = 0x00000004,
        VK_VIDEO_ENCODE_USAGE_CONFERENCING_BIT_KHR = 0x00000008,
    } VkVideoEncodeUsageFlagBitsKHR;

## Description

- `VK_VIDEO_ENCODE_USAGE_TRANSCODING_BIT_KHR` specifies that video encoding is intended to be used in conjunction with video decoding to transcode a video bitstream with the same and/or different codecs.

- `VK_VIDEO_ENCODE_USAGE_STREAMING_BIT_KHR` specifies that video encoding is intended to be used to produce a video bitstream that is expected to be sent as a continuous flow over network.

- `VK_VIDEO_ENCODE_USAGE_RECORDING_BIT_KHR` specifies that video encoding is intended to be used for real-time recording for offline consumption.

- `VK_VIDEO_ENCODE_USAGE_CONFERENCING_BIT_KHR` specifies that video encoding is intended to be used in a video conferencing scenario.

Note | There are no restrictions on the combination of bits that can be specified by the application. However, applications should use reasonable combinations in order for the implementation to be able to select the most appropriate mode of operation for the particular use case.
