[extractor/youtube] Download post_live
videos from start (#5091)
* The fragments are generated as a `LazyList`. So only the required formats are expanded during download, but all fragment lists are printed/written in infojson. * The m3u8 formats which cannot be downloaded from start are not extracted by default, but can be enabled with an extractor-arg. The extractor-arg `include_live_dash` is renamed to `include_incomplete_formats` to account for this new use-case. Closes #1564 Authored by: Lesmiscore, pukkandan

@ -1704,7 +1704,7 @@ 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_live_dash`: Include live dash formats even without `--live-from-start` (These formats don't download properly)
|
||||
* `include_incomplete_formats`: Extract formats that 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
