Nvidia and AMD both have differing APIs for video decoding. The idea in using Vulkan is that not every GPU supports the vendor specific decoding method, but they do all support Vulkan (modern GPUs, anyways). So this way you still get hardware accelerated decoding through a more widely supported means.
