FFmpeg installed but failed to execute

Error message

FFmpeg installed but failed to execute (exit code {})

What it means

After installation, download_ffmpeg() executes `ffmpeg -version` to verify the binary works. If the process runs but exits with a non-zero status, this error reports the exit code — the binary exists but is not usable on this system.

Solutions

1. Run the installed binary manually from a terminal to see the real error (e.g. missing .so files)
2. Install the missing shared libraries reported by ldd/otool
3. Download the archive variant matching the CPU architecture and OS
4. On macOS, clear quarantine attributes (xattr -d com.apple.quarantine) or re-sign
5. Re-run ensure_ffmpeg to replace a possibly corrupted binary

let st = std::process::Command::new(&ffmpeg_path).arg("-version").status()?;
if !st.success() {
    eprintln!("ffmpeg unusable on this system (exit {:?})", st.code());
}

match download_ffmpeg().await {
    Ok(p) => ...,
    Err(e) if e.to_string().contains("failed to execute") => {
        eprintln!("install a distro ffmpeg or pick the matching build");
    }
    Err(e) => ...,
}

When it happens

Trigger: The extracted ffmpeg binary launches but terminates non-zero: missing shared libraries on Linux, corrupted/incomplete binary, wrong architecture (x86 binary on ARM), or macOS codesigning/quarantine issues.

Common situations: Downloading a glibc-incompatible Linux build; wrong-arch archive for the platform; partially written binary that survived the size check; missing system libraries (libxcb etc.).
