This is what seems to have helped for me on Fedora:
sudo dnf groupupdate multimedia --setop="install_weak_deps=False" --exclude=PackageKit-gstreamer-plugin
sudo dnf groupupdate sound-and-video
sudo dnf install mozilla-openh264
rm ~/.cache/gstreamer-1.0/registry.x86_64.bin
I was having trouble with many h265 videos until I cleared my gstreamer cache (I only needed to clear the 64-bit cache, this thread suggests clearing both 32 and 64-bit):
