Scrape only vaguely works. You'd be crazy to want to use it.
- It attempts to download several resources simultaneously. This tends to fail for a variety of reasons. It works best for short HLS streams with few variants.
- It doesn't reload playlists. That means for live streams, it will only download a snapshot of resources that are exposed at the point in time a playlist is fetched.
- It preserves directory structure, which is sometimes good, and sometimes catastrophic. Cross-domain resources are especially problematic.
- It reports progress by telling you what is downloaded, nothing about what remains.
- It doesn't let you select a variant. It's all or nothing.
- It doesn't retry on failure.
