VK_Video

Description

This is a sample showing how to use Vulkan Video. Developer's MUST have FFMPEG development libraries installed. FFMPEG is used for demuxing duties only. This sample attempts to make a generic library out of the NVIDIA Vulkan Video Sample to show how it can be used in a more generic way. As this is a very complex sample, it likely will take many revisions before landing.

NB: Vulkan Video is only supported in desktop environments. Also, it isn't required to ultimately use FFMPEG, one can use things like https://github.com/lieff/minimp4 or similar to handle the demuxing. However; that would only support h264 while FFMPEG is well tested and supports all codecs. Working on a demuxing solution is beyond the scope of this sample; but it is possible to do.

Tested in Linux on NVIDIA hardware.

General Checklist:

Please ensure the following points are checked:

• My code follows the coding style
• I have reviewed file licenses
• I have commented any added functions (in line with Doxygen)
• I have commented any code that could be hard to understand
• My changes do not add any new compiler warnings
• My changes do not add any new validation layer errors or warnings
• I have used existing framework/helper functions where possible
• My changes do not add any regressions
• I have tested every sample to ensure everything runs correctly
• This PR describes the scope and expected impact of the changes I am making

Note: The Samples CI runs a number of checks including:

• I have updated the header Copyright to reflect the current year (CI build will fail if Copyright is out of date)
• My changes build on Windows, Linux, macOS and Android. Otherwise I have documented any exceptions

If this PR contains framework changes:

• I did a full batch run using the batch command line argument to make sure all samples still work properly

Sample Checklist

If your PR contains a new or modified sample, these further checks must be carried out in addition to the General Checklist:

• I have tested the sample on at least one compliant Vulkan implementation
• If the sample is vendor-specific, I have tagged it appropriately
• I have stated on what implementation the sample has been tested so that others can test on different implementations and platforms
• Any dependent assets have been merged and published in downstream modules
• For new samples, I have added a paragraph with a summary to the appropriate chapter in the readme of the folder that the sample belongs to e.g. api samples readme
• For new samples, I have added a tutorial README.md file to guide users through what they need to know to implement code using this feature. For example, see conditional_rendering
• For new samples, I have added a link to the Antora navigation so that the sample will be listed at the Vulkan documentation site

Haven't had time to do a proper review yet, but it looks like this PR downgrades the asset submodule to a very old version, which would remove several assets used by some of the recent examples.
