Hi,

this is on Fedora 38 (on ARM64) and it seems like the Mpv rust binding thinks it wants to expect and load a too old native libmpv, whereas the installed libmpv on the system seems to be way newer. NB: i was just git clone'ing the repo, as there seems to be no ARM64 native builds. Compiling works, executing the binary does not.

christianparpart@fedora-arm64-vm ~/u/s/t/ytui-music (main)> dnf info mpv-libs

when executing the binary:

Is there any chance to work around this, get fixed, or something else?

p.s.: great project, would love to use it!

Same here. OS: ArchLinux

$> pacman -Qi ytui-music
Name            : ytui-music
Version         : 2.0.0rc1-1

$> pacman -Qi mpv
Name            : mpv
Version         : 1:0.35.1-6

I get the same error on ArchLinux, using version 2.0.0-rc1.

Replacing the problematic unwrap() with some error handling yields the below error details:

VersionMismatch { linked: 65644, loaded: 131072 }

This seems to corroborate what @christianparpart said about the mpv version.

Hello guys I found a solution to this. The problem is that libmpv-rs crate was not updated, however the repo itself is updated. So what you need to do is download the repo and tell cargo to look for local libmpv-rs.

To do this paste the following inside Cargo.toml :

[patch.crates-io]
libmpv = { path = "../libmpv-rs" }

( I cloned it in the same parent directory as ytui-music )

Can we get a proper fix submitted as a PR to this project instead, such that all users can benefit from it with least impact?
