[SOLVED] Run "scrcpy" Commands And Throws Error "libopenh264.so.7 is missing" / "openh264 disabled"

Issue

I try to run scrcpy command like what I did before, and proved if it's worked not just once.

scrcpy -m 540 -S

but after re-installing my OS and use Fedora OS with dnf package manager, I got errors with output below.

WARN: Demuxer 'audio': stream explicitly disabled by the device
WARN: [FFmpeg] libopenh264.so.7: cannot open shared object file: No such file or directory: libopenh264.so.7 is missing, openh264 support will be disabled
ERROR: Demuxer 'video': could not open codec
ERROR: Demuxer error
[server] INFO: Device screen turned off

Seems I got a problem here because [FFmpeg] libopenh264.so.7 is missing and it cause openh264 support disabled.

Solution

After trying some commands that I found from Google, I found some articles with better relation to my problem.

https://discussion.fedoraproject.org/t/dnf-update-fails-with-ffmpeg-libs/82595/3

And finally, after running the command below,

sudo dnf install openh264 mozilla-openh264

And then retrying to run the command below,

scrcpy -m 540 -S

My problem solved, and scrcpy worked like a charm.
