All playlist item(s) failed to download. First error

Error message

All {} playlist item(s) failed to download. First error: {}

What it means

After iterating all playlist items, download_playlist() reports total failure if success_count == 0. It includes the first item's error as detail ('unknown error' if none was captured) so the caller learns why every item failed.

Solutions

1. Inspect 'First error: ...' in the message — fix the underlying per-item error it reports.
2. Re-fetch media info right before downloading so CDN URLs are fresh, then retry.
3. Check network/proxy connectivity and account cookies if the first error mentions auth or 403.
4. Improve the code to aggregate all item errors (not just the first) for better diagnostics.

Example fix

// before
return Err(anyhow!("All {} playlist item(s) failed to download. First error: {}", total, detail));
// after
let details: Vec<String> = item_errors.iter().map(|e| e.to_string()).take(3).collect();
return Err(anyhow!("All {} playlist item(s) failed. First errors: {}", total, details.join("; ")));

match download(...).await {
    Err(e) if e.to_string().starts_with("All ") && e.to_string().contains("playlist item(s) failed") => {
        let first = extract_first_error(&e.to_string());
        retry_with_fresh_info(url).await
    }
    other => other,
}

When it happens

Trigger: download() -> download_playlist() where every playlist item's download future returned Err (network failures, expired CDN URLs, per-item extraction errors), leaving success_count at 0.

Common situations: Bilibili CDN URLs expired because fetching info and downloading were separated by too long; network/proxy outage; all items hit the same auth or region restriction; the per-item downloader has a systematic bug after an API change.
