Question: ffmpeg not working as a sidecar (dydl issues)

[noidwasavailable]

Hi! I am building a Tauri project using ffmpeg. I am not able to get my ffmpeg to work as a sidecar.

dyld[48903]: Library not loaded: @loader_path/../lib/libavdevice.60.dylib

I am calling it on my rust side using Command, but trying it similarly on the JavaScript side didn't yield much results either.

#[tauri::command]
async fn merge_video_and_audio(url: String, start: i32, end: i32) -> String {
    ...

    // This works
    // let output = Command::new("ffmpeg").args(&args).output().unwrap();
    
    // But this does not work
    let output = Command::new_sidecar("ffmpeg")
        .expect("why not working bro")
        .args(&args)
        .output()
        .unwrap();
    println!("{}", output.stdout);
    if output.status.success() {
        println!("Message from Rust: Merged");
    } else {
        println!("Message from Rust: Failed to merge");
        println!("{}", output.stderr);
        return format!("Failed");
    }

    ...
}

If I just use my local version of ffmpeg using Command::new("ffmpeg") it works, but only in development.

> which ffmpeg
/opt/homebrew/bin/ffmpeg

The build version works too, but only the executable created, but not the bundled version.

src-tauri/
├── target/
│   └── debug(or release)/
│       ├── yt-video-downloader <-- this executable works
│       └── bundle/
│           ├── dmg/
│           │   └── yt-video-downloader-something.dmg <-- installing through this does not work
│           └── macos /
│               └── yt-video-downloader.app <-- this does not work
└── ...

I assume I cannot deliver just the executable to another computer and hope it works.

How can I get either of the following working?

1. Get ffmpeg to load as a sidecar so I don't have to be calling the local version of ffmpeg, in a way that will work through bundling?
2. Get my current setup using the local version of ffmpeg working through bundling?
