@ -1798,6 +1798,8 @@ The following extractors use this feature:
#### generic
* `fragment_query`: Passthrough any query in mpd/m3u8 manifest URLs to their fragments. Does not apply to ffmpeg
* `variant_query`: Passthrough the master m3u8 URL query to its variant playlist URLs
* `hls_key`: An HLS AES-128 key URI *or* key (as hex), and optionally the IV (as hex), in the form of `(URI|KEY)[,IV]`; e.g. `generic:hls_key=ABCDEF1234567980,0xFEDCBA0987654321`. Passing any of these values will force usage of the native HLS downloader and override the corresponding values found in the m3u8 playlist
#### funimation
* `language`: Audio languages to extract, e.g. `funimation:language=english,japanese`
