Playback failed with error "unrecognized file format"

[M B]

here is what is weird in the client log

2025-06-14 21:29:36.994 [critical] unknown @ 0 - ffmpeg: tcp: Failed to resolve hostname media.lan: The name does not resolve for the supplied parameters

so for some reason , even if we are addressing a local server in my home network, ffmpeg cant resolve it.

why? does ffmpeg has its own dns configuration??
