I noticed that NVDEC wasn't available.  It got lost over the weekend 
when the 495 series became the default nvidia driver in F34 and I had to 
specify 470xx to keep support for my card.  NVDEC is from the cuda 
packages, brought in by 'dnf install xorg-x11-drv-nvidia-470xx-cuda'

With that done, and the NVDEC decoder selected, this clip plays well and 
the log has no lines about caption services.
