Ranjan,
I'm having the same packages as you (openh264, ... and a trunkload of MORE stuff from "outside fedora") and never have experienced any problem when upgrading.
That said, you didn't explicitly mention whether you did **install the "Fedora update utility"** Could it be you didn't do that: "sudo dnf install dnf-plugin-system-upgrade"
FWIW, to be on the safe side (sorry if this of no help) here's the process: - create a backup - upgrade all installed packages of Fedora version 31 by running "sudo dnf upgrade --refresh" - reboot by typing "sudo reboot" if kernel update was installed - Install Fedora update utility by "sudo dnf install dnf-plugin-system-upgrade" - start the upgrade procedure and download packages "sudo dnf system-upgrade download --releasever=32" - reboot and complete upgrade: "sudo dnf system-upgrade reboot" - verify upgrades
As said, you didn't mention whether you went thru this process, so just wanted to make sure we're on the same page. HTH, Thomas
