Update player.js reverting #2062, fixes #1342 #1652 #1904

[raszpl]

reverting implementation of #2061 , bad idea, YT internally uses same parameter markers so we cant really distinguish between YT resuming and someone opening link with timestamp

this.elements.player.seekTo(0) rewinds, but with side effects of triggering play()

switch from this.elements.player.seekTo(0) to this.elements.video.currentTime = 0 didnt work. YT player actually reads currentTime and will hang while hammering currentTime(whatever) if it doesnt get what it wants :0. Back to seekTo(0) with optional check for paused.

Edit: further testing shows

• on this link https://www.youtube.com/watch?v=mrbFpLwLQAk&t=568s YT executes video.play() 3 times in FF and 3-5 times in Chrome!
• first YT executed .play() and seek using currentTime(x) happens before extension manages to even load storage some of the time, but not always - this might be the source of randomly not working. If we are slow enough forcedPlayVideoFromTheBeginning works, if we load fast and our forcedPlayVideoFromTheBeginning() is executed too early YT will happily read currentTime, see its not what it set and set it again.
• YT really reaaaly wants that seek, if I shimm currentTime:

Object.defineProperty(HTMLMediaElement.prototype, 'currentTime', {
	enumerable: true,
	configurable: true,
	get: function() {
		return ImprovedTube.HTMLMediaElement.get.apply(this, arguments);
	},
	set: function(newValue) {
		console.log('early set', newValue);
		if (newValue != 0) {
			this.currentTime = 0;
			ImprovedTube.HTMLMediaElement.set.apply(this, [0]);
		}
	}
});

video wont play at all and console shows

YT knows something is wrong and keeps trying :(

To make forcedPlayVideoFromTheBeginning reliable it would have to either trigger way late causing annoying rewind every time, or finally make autoplayDisable reliably stop without playing a single frame. Second option seems better.

hi! @raszpl

can start with if (this.storage.forced_play_video_from_the_beginning , paused= inside

#2061

why not check !this.video_url.match(this.regex.video_time) ?

[raszpl]

can start with if (this.storage.forced_play_video_from_the_beginning , paused= inside

variable declarations on top of function are more readable, reading video?.paused is free, declaring empty let paused just to fill it inside condition is more typing :)

why not check !this.video_url.match(this.regex.video_time) ?

because "reverting implementation of #2061 , bad idea, YT internally uses same parameter markers so we cant really distinguish between YT resuming and someone opening link with timestamp"

We can either respect forced_play_video_from_the_beginning on all videos or users will complain its not working in some situations. It still fails sometime as explained in the Edit :( the later its being executed the more reliable it is, but at the cost of annoying jump if Autoplay is enabled. Bet option is to work on fully reliable autoplayDisable, I already have something almost working.

hi @raszpl,
youtube will add the t= parameter to the URL bar? under which circumstance? (then can keep !this.video_url.match(this.regex.video_time), when navigation to get there happened through a link or bookmark.) (and i'm just applying the principle of preparing for later, "hoarding comments & code. While Developer time is our only limit but this project might have double the meanningful code sooner than the "existing half" took #2233 (comment) )

#2061 (comment)

[raszpl]

wait, what is "#t=" ? Where did you saw "#t" usage? # (hash) is used for anchor navigation in links.
Please post code links, those images are to "private-user-images" and often dont render at all :(
