********************************************************************************
Functions of this script:
It displays thumbnail images instead of auto-playing videos on channel pages, individual video pages, etc.
You can play the thumbnail videos by mouse click or [Space] key.
Advertisements and live streamings would automatically start normally.

本スクリプトの機能:
チャンネルページや個別の動画ページなどで、動画を自動再生せず、サムネイル画像を表示します。
サムネイル画像になった動画は、マウスクリックや [スペース] キーなどで再生できます。
広告映像やライブ配信では、通常どおり自動で再生を開始します。

[bug]
[todo]
[possible]
channel/ と watch/ は個別に設定可能とか
=> channelだけで動作する別スクリプトがある
document.hidden でのみ作動するオプションとか
0秒で常にサムネに戻る仕様(seekingイベントでよい)
[research]
シアターモードの切り替えで再生してしまう件(そこまで気にしなくてもいい気もする)
t=4 以下で seek 後にサムネイルが消えてしまう問題
たまにぐるぐるが止まらない問題 t 指定とキャッシュに関係ある？
[memo]
本スクリプト仕様:
サムネになってほしい: チャンネルホーム, ビデオページ
再生してほしい: LIVE, 広告, 途中広告からの復帰
要確認: 各ページの行き来, 再生で即停止しないこと, シアターモードの切り替え, 背面タブでの起動
(YouTubeによるあっぱれなユーザー体験の追究のおかげで、初回読み込み時に限り再生開始済みのvideo要素が即出現する)
YouTube仕様:
画面更新(URL Enter, S-Reload, Reload に本質的な差異なし)
新規タブ(開いた直後, 読み込み完了後, title変更後 に本質的な差異なし)
video: body ... video ... loadstart ... で必ず play() されるのでダミーと入れ替えておけばよい。
video要素は #player-api 内に出現した後に ytd-watch-flexy 内に移動する。その際に play() されるようだ。
t=123 のような時刻指定があると seeking 後にもう一度 play() される。
thumbnail は t=4 以下だとなぜか消えてしまう。(seekじゃなくてadvanceだとみなされるせい？)
channel: body ... video ... loadstart で即 pause() 可能。(playは踏まれない)
画面遷移(動画 <=> LIVE <=> チャンネル)
video: yt-navigate-start ... loadstart で即 pause() 可能。(playは踏まれない)
広告
冒頭広告: .ad-showing 依存だが判定できる。
広告明け: 少しだけ泥臭いが、そのURLで一度でも本編が再生されていれば広告明けとみなす。
参考:
Channelトップの動画でのみ機能するスクリプト
