The following extractors use this feature:
* **youtube**
* `skip`: `hls` or `dash` (or both) to skip download of the respective manifests
* `player_client`: `web`(default) or `android` (force use the android client fallbacks for video extraction)
* `player_skip`: `configs`- skip requests if applicable for client configs and use defaults
