@ -1805,8 +1805,7 @@ The following extractors use this feature:
* `comment_sort`: `top` or `new` (default) - choose comment sorting mode (on YouTube's side)
* `max_comments`: Limit the amount of comments to gather. Comma-separated list of integers representing `max-comments,max-parents,max-replies,max-replies-per-thread`. Default is `all,all,all,all`
* E.g. `all,all,1000,10` will get a maximum of 1000 replies total, with up to 10 replies per thread. `1000,all,100` will get a maximum of 1000 comments, with a maximum of 100 replies total
* `include_duplicate_formats`: Extract formats with identical content but different URLs or protocol. This is useful if some of the formats are unavailable or throttled.
* `include_incomplete_formats`: Extract formats that cannot be downloaded completely (live dash and post-live m3u8)
* `formats`: Change the types of formats to return. `dashy` (convert http to DASH), `duplicate` (identical content but different URLs or protocol; includes `dashy`), `incomplete` (cannot be downloaded completely - live dash and post-live m3u8)
* `innertube_host`: Innertube API host to use for all API requests; e.g. `studio.youtube.com`, `youtubei.googleapis.com`. Note that cookies exported from one subdomain will not work on others
* `innertube_key`: Innertube API key to use for all API requests
