@ -1340,6 +1340,9 @@ The following extractors use this feature:
* `language`: Languages to extract. Eg: `funimation:language=english,japanese`
* `version`: The video version to extract - `uncut` or `simulcast`
* **vikiChannel**
* `video_types`: Types of videos to download - one or more of `episodes`, `movies`, `clips`, `trailers`
NOTE: These options may be changed/removed in the future without concern for backward compatibility
