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.
