Enable --concurrent-fragments #81

Closed ridgewell closed 2 years ago

ridgewell commented 2 years ago

Youtube Dash formats can be slow to download as they download fragment-by-fragment. This is not throttling but a design of Dash formats.

Does it make sense to enable yt-dlp's --concurrent-fragments (-N) with 4 or 8 threads to mitigate this issue? This mitigates the slowness of single-threaded download of dash files without requiring the use of an external downloader such as aria2.

Thank you for looking into this.

This is a good idea from a download speed perspective, but I'm a bit scared that this will cause some bugs/weirdness when merging the fragments. So I'm not sure it's "safe".

After running my scripts for a while, I discovered that it's actually needed, otherwise things end up timing out.
