Thank you. Setting this environment helped to remove the first error 
message

    export ANV_VIDEO_DECODE=1
    vulkaninfo | grep VK_KHR_video_decode_queue
      VK_KHR_video_decode_queue                     : extension revision 8

Still remaining hwaccel initialisation returned error for h264 and h265 
input respectively:

    [h264 @ 0x55952760cf40] Failed setup for format vulkan: hwaccel
    initialisation returned error.

    [hevc @ 0x5580e96e8c80] Failed setup for format vulkan: hwaccel
    initialisation returned error.
    [hevc @ 0x5580e96e8c80] Unsupported film grain parameters. Ignoring
    film grain.
