Got this error when trying to run the compiled binary. All the dependencies are already installed. Am I missing something here?

I am using Ubuntu 20.10 with AMD process and Nvidia 1060. I got the same problem when try to use the UxPlay .But You should try to use the original project :
https://github.com/FD-/RPiPlay

Even It mentions it is for Raspberry pi . However, it works for me. Good luck !

there is an updated UxPlay pr #58. maybe you didnt install the libav plugin?

This helped me: https://narkive.com/tlRb4aoQ.4
tl;dr:
Remove ~/.cache/gstreamer-1.0/registry.*.bin and try running ./uxplay again. It should work then.
