Many solutions Requires copy video to memory then from memory copy to texture.
Its very slow ! And fps on 1080p video less 15 !
And my question did Vulkan have fast way work with 1080p video ?
Vulkan is a rendering API, not recording one. NVIDIA, AMD and Intel have proprietary libraries to access encoding capabilities of their GPUs, or you can try to work something out with open-source libraries like ffmpeg.
