Vulkan Profile Video Profiles

The table below lists the video profiles (or class of video profiles) that any profile defines requirements for. Video profile names take the following form:

"(General|[<codec>] <category>) [([<subsampling>] [<bits>])] [<codecSpecificProfileInfo>]"

"General" refers to general requirements for all video profiles.
<category> is the category of the video profile requirements (e.g. "Decode" or "Encode").
<codec> identifies the specific codec (e.g. H.264, H.265, AV1) the requirements apply to. If not indicated, the requirements apply to all supported video profiles falling in the specified category.
<subsampling> indicates the chroma subsampling (e.g. 4:2:0, 4:2:2, 4:4:4, or monochrome). If not indicated, the requirements apply to all supported chroma subsampling modes.
<bits> indicates the luma and chroma bit depth (e.g. 8-bit, 10-bit, or e.g. 10:8-bit for mixed bit depths). If not indicated, the requirements apply to all supported bit depths. Partial, luma-only or chroma-only "wildcard" requirements are indicated with an asterisk in place of the corresponding bit depth (e.g. 10:*-bit or *:8-bit).
<codecSpecificProfileInfo> indicates additional codec-specific video profile information (e.g. "Main", "High"). If not indicated, the requirements apply to all video profiles of the codec.
✔️ indicates that the profile defines requirements for the video profile (or class of video profiles)
❌ indicates that that the profile does not define requirements for the video profile (or class of video profiles)
