@ -1736,6 +1736,9 @@ The following extractors use this feature:
* `skip`: One or more of `webpage` (skip initial webpage download), `authcheck` (allow the download of playlists requiring authentication when no initial webpage is downloaded. This may cause unwanted behavior, see [#1122](https://github.com/yt-dlp/yt-dlp/pull/1122) for more details)
* `approximate_date`: Extract approximate `upload_date` and `timestamp` in flat-playlist. This may cause date-based filters to be slightly off
#### generic
* `fragment_query`: Passthrough any query in mpd/m3u8 manifest URLs to their fragments. Does not apply to ffmpeg
#### funimation
* `language`: Audio languages to extract, e.g. `funimation:language=english,japanese`
* `version`: The video version to extract - `uncut` or `simulcast`
