The index was set to index - 1, causing the first video to be shifted in fetch_playlist_videos
(because of its index being -1 lower than it should) and thus not displayed on playlist page.
Using the player on latest Safari, the tooltip appears and stays stuck for long even when switching to fullscreen which is annoying. You need to explicitly click anywhere to dismiss that stuck tooltip.
This doesn't seem to happen in Firefox so I am not sure whether this is a browser bug, but in any case I don't see any value in keeping this tooltip so maybe we can just remove it?
* Use new API to fetch videos from channels
This mirrors the process used by subscriptions.gir.st. The old API is
tried first, and if it fails then the new one is used.
* Use the new API whenever getting videos from a channel
I created the get_channel_videos_response function because now instead
of just getting a single url, there are extra steps involved in getting
the API response for channel videos, and these steps don't need to be
repeated throughout the code.
The only remaining exception is the bypass_captcha function, which still
only makes a request to the old API. I don't know whether this code
needs to be updated to use the new API for captcha bypassing to work
correctly.
* Correctly determine video length with new api
* Remove unnecessary line
* More consistent IDs for info section
More consistent IDs for info section: watch-on-youtube, annotations and download
* Consistent IDs: channel-name
* Consistent IDs: published-date
The term "published" can also be found in the answer for the following YouTube API request: https://developers.google.com/youtube/v3/docs/videos/list
