Please do not post screenshots of your terminal, just post the content as text instead.

Start by reproducing the `scrcpy` command on Fedora 38 with the COPR installation and check the reported `libopenh264.so.7` warning and codec errors. Inspect the package dependencies and the console output; done means scrcpy starts successfully and mirrors the listed Android devices without the demuxer failure.
