No URL available

Error message

No URL available

What it means

`download` takes the first entry of `info.available_qualities` and treats its `url` as the media stream; if the qualities list is empty or the first quality's URL is an empty string it throws `No URL available`. This protects against launching yt-dlp with a blank target.

Solutions

1. Check `info.available_qualities` is non-empty and the first URL is non-blank before calling download.
2. Re-run `get_media_info` to refresh stream URLs — they can expire and extraction may have failed silently.
3. Ensure the user is logged in / cookies are configured when streams require authentication.
4. Pick a specific quality explicitly rather than relying on `.first()` defaults.

Example fix

// before
download(info, opts, progress).await?; // panics if qualities empty
// after
if info.available_qualities.first().map(|q| q.url.is_empty()).unwrap_or(true) {
    info = get_media_info(&source_url).await?;
}
download(info, opts, progress).await?;

fn has_stream(info: &MediaInfo) -> bool {
    info.available_qualities.first().map(|q| !q.url.is_empty()).unwrap_or(false)
}

match download(info, opts, progress).await {
    Err(e) if e.to_string().contains("No URL available") => refresh_info_and_retry().await?,
    Err(e) => return Err(e),
    Ok(_) => {},
}

When it happens

Trigger: Passing a MediaInfo produced by a failed/incomplete `get_media_info` call where `available_qualities` is empty, or where quality entries were built with empty `url` fields (e.g. extraction returned metadata but no stream URLs, or a hand-constructed MediaInfo).

Common situations: Chaining get_media_info → download without checking that qualities were populated; Bilibili returning metadata but stream extraction blocked (login/region); constructing MediaInfo manually in tests/fixtures with placeholder qualities.
