Feature description

YouTube has this URL that creates a playlist on the fly:

http://www.youtube.com/watch_videos?video_ids=$videoIDs

where $videoIDs is a comma-separated list of video IDs (vid1,vid2,...,vidN).

For instance, this URL creates a playlist with 3 videos:

http://www.youtube.com/watch_videos?video_ids=16J5TrCIEB4,8BsHd52ric0,nc_H-bD2khc

The newly created playlist:

• doesn't have a title
• isn't associated with a YouTube account
  (you don't have to be logged in).
• is temporary
  (I don't know exactly for how long it lasts, but if you save the URL (not this one, the playlist URL that YT redirects you to upon creation) and try to view it again in a few days -- it's gone.)
• Has a maximum length of 50 items.

It would be great if NewPipe had an option to share a playlist in this format too.

The "Share Playlist" dialog could have a a 3rd option called, e.g., "Share as YouTube temporary playlist".

Why do you want this feature?

This would be great for:

• Sharing a playlist from your mobile to the desktop
• Sharing with other people

This could be very useful as a temporary workaround when ever YouTube parsing fails again, which seems to occur more frequently.

I group a fair number of the short news clips into my Current playlist.
When NewPipe has a problem, individually clicking play in browser gets old very fast.

A temporary playlist that I can route to my (default) ad blocking browser would be a great workaround to tide people over while NewPipe creators fixes the problem.

Note: I can export the playlist as URLS (with/out names) but the players still only play the first URL.

FWIW, I kludge up a semi-auto way to do this via Excel.
And it works, a bit kludgy though.

I exported the list from NewPipe to Telegram.
Then I copy & paste that message into excel
That gives me a URL that I then send to Brave or DuckDuckGo browsers to play said list.
Works! It shows untitled list on YouTube.

Now I face a second issue.

Now that I have exported the playlist that is usable by a browser, I have no easy ways to mark them as watched on NewPipe so I can delete them off NewPipe.

Can add a feature to select individual or all videos in a playlist?
if that is too messy, how about a selection to clear a playlist?

So, I'm working on the implementation and one of the things I came across is i18n.

There's a new button, with a label. So, a new R.string.xyz will have to be created, I guess (currently it's hard-coded).

private void createShareConfirmationDialog() {
    new AlertDialog.Builder(requireContext())
        .setTitle(R.string.share_playlist)
        .setMessage(R.string.share_playlist_with_titles_message)
        .setCancelable(true)
        .setPositiveButton(R.string.share_playlist_with_titles, (dialog, which) ->
            sharePlaylist(WITH_TITLES)
        )
        // TODO           R.string.share_playlist_as_YouTube_temporary_playlist     // <= here
        .setNeutralButton("Share as YouTube temporary playlist", (dialog, which) -> // <= here
            sharePlaylist(YOUTUBE_TEMP_PLAYLIST)
        )
        .setNegativeButton(R.string.share_playlist_with_list, (dialog, which) ->
            sharePlaylist(JUST_URLS)
        )
        .show();
}

1. I have never done this before; figuring things out as I go. Any orientation/recommendation the developers would like to give me?
2. What is the process for this? Do all the translators get notified and only after all of them have finished is the PR ready to be merged?

Besides the English version, I can take care of the pt-br translation as well.
