 #### youtube
 * `lang`: Prefer translated metadata (`title`, `description` etc) of this language code (case-sensitive). By default, the video primary language metadata is preferred, with a fallback to `en` translated. See [youtube/_base.py](https://github.com/yt-dlp/yt-dlp/blob/415b4c9f955b1a0391204bd24a7132590e7b3bdb/yt_dlp/extractor/youtube/_base.py#L402-L409) for the list of supported content language codes
 * `skip`: One or more of `hls`, `dash` or `translated_subs` to skip extraction of the m3u8 manifests, dash manifests and [auto-translated subtitles](https://github.com/yt-dlp/yt-dlp/issues/4090#issuecomment-1158102032) respectively
-* `player_client`: Clients to extract video data from. The currently available clients are `web`, `web_safari`, `web_embedded`, `web_music`, `web_creator`, `mweb`, `ios`, `android`, `android_vr`, `tv`, `tv_downgraded`, and `tv_simply`. By default, `android_vr,web,web_safari` is used. If no JavaScript runtime/engine is available, then only `android_vr` is used. If logged-in cookies are passed to yt-dlp, then `tv_downgraded,web,web_safari` is used for free accounts and `tv_downgraded,web_creator,web` is used for premium accounts. The `web_music` client is added for `music.youtube.com` URLs when logged-in cookies are used. The `web_embedded` client is added for age-restricted videos but only successfully works around the age-restriction sometimes (e.g. if the video is embeddable), and may be added as a fallback if `android_vr` is unable to access a video. The `web_creator` client is added for age-restricted videos if account age-verification is required. Some clients, such as `web_creator` and `web_music`, require a `po_token` for their formats to be downloadable. Some clients, such as `web_creator`, will only work with authentication. Not all clients support authentication via cookies. You can use `default` for the default clients, or you can use `all` for all clients (not recommended). You can prefix a client with `-` to exclude it, e.g. `youtube:player_client=default,-web`

 * `player_skip`: Skip some network requests that are generally needed for robust extraction. One or more of `configs` (skip client configs), `webpage` (skip initial webpage), `js` (skip js player), `initial_data` (skip initial data/next ep request). While these options can help reduce the number of requests needed or avoid some rate-limiting, they could cause issues such as missing formats or metadata.  See [#860](https://github.com/yt-dlp/yt-dlp/pull/860) and [#12826](https://github.com/yt-dlp/yt-dlp/issues/12826) for more details
 * `webpage_skip`: Skip extraction of embedded webpage data. One or both of `player_response`, `initial_data`. These options are for testing purposes and don't skip any network requests. Neither is skipped by default; however, if a `player_js_version` value other than `actual` is used, then `webpage_skip=player_response` is implied
 * `webpage_client`: Client to use for the video webpage request. One of `web` or `web_safari` (default)
 * `player_params`: YouTube player parameters to use for player requests. Will overwrite any default ones set by yt-dlp.
-* `player_js_variant`: The player javascript variant to use for n/sig deciphering. The known variants are: `main`, `tcc`, `tce`, `es5`, `es6`, `es6_tcc`, `es6_tce`, `tv`, `tv_es6`, `phone`, `house`. The default is `tv`, and the others are for debugging purposes. You can use `actual` to go with what is prescribed by the site

 * `player_js_version`: The player javascript version to use for n/sig deciphering, in the format of `signature_timestamp@hash` (e.g. `20348@0004de42`). The default is to use what is prescribed by the site, and can be selected with `actual`. Using any other value will imply `webpage_skip=player_response`
 * `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,max-depth`. Default is `all,all,all,all,all`
