HTML5 player is sometimes not removed from the site properly

[FRex]

I'm on a Linux machine with no flash plugin for Firefox and sometimes the script fails to kill HTML5 player so it starts playing in the background with no way to stop it other than closing the tab. This has happened very recently, but I'm not exactly sure when, I noticed today, before everything was working as indended. Everything I have is up to date.

I also noticed few things:

1. If I pick video from somewhere like videos page of the user, then the HTML5 player won't start.
2. If I go to another video while the one behind VLCTube plays, it won't stop. It seems the HTML5 player only plays when the video page is fully loaded, but not when the YouTube's AJAX-esque partial loads takes you from videos list or search result or between videos.

I tried to opt for Flash player instead of HTML5 one in YouTube so I'd get an error behind the VLCTube interface, but YouTube detects that I don't have Flash and HTML5 still works.

I have very few addons and scripts that work on YouTube, but they can't interfere with this, didn't interfere in the past and disabling everything except VLCTube didn't fix the issue.

My specs are: Fedora 21, Linux 3.19.7-200.fc21.i686 Mozilla Firefox 38.0 release 4.fc21 Greasemonkey 3.1 npapi-vlc-filesystem, npapi-vlc and npapi-vlc-gtk libs: 2.2.0 release 0.1.fc21 vlc and vlc-core packages: 2.2.1 release 2.fc21 libvlc.so.5 links to libvlc.so.5.5.0 and comes from vlc-core package

I've got the exact same issue as well. Windows 7 Firefox 38.0.1 Greasemonkey 3.1 VLC Web Plugin 2.2.1.0

try this https://addons.mozilla.org/en-us/firefox/addon/flashstopper/ tell me if it makes any difference, i suggest this one because flashblock doesnt always work anymore

[FRex]

Flash block doesn't work ever on HTML5 in Firefox for me anymore but it used to. This works when VLC is off, but with VLCTube on it doesn't and the video still starts in the background.

[PierceZ]

Thanks @Sonic0170 that did it for me. No longer getting double playing videos.

[Sonic0170]

i see so it works for windows users but its something more complicated for linux users, that's interesting, hope this gives you some insight on what the issue could be @jackun

[FRex]

It might be that @PierceZ has Flash, and I don't at all because Flash from Adobe is really bad and feature frozen since version 11 for everything except Chrome which bundles its' own.

[PierceZ]

I do indeed have flash, I thought youtube stopped using flash though? Perhaps not entirely.

[Sonic0170]

thing is when i have vlctube off html5 plays by default on firefox for windows on youtube, seems like flash has been nearly phased out, flash is only used as an emergency fallback now, i assume only if its played on a non-html5 compatible browser (webm/mp4)

[PierceZ]

Same for me @Sonic0170 I can only assume the flash stopper plugin is pausing it for me despite not actually using flash.

[Sonic0170]

flashstopper works with flash and html5 like how flashblock used to, my theory i was hoping for is if both players are still loading at the same time thus playing the same videos twice that this would stop the html5 from playing while vlctube continues to play normally, but sadly this test didn't work for linux

[Sonic0170]

now this double playing doesnt happen to me but i wanted to see if this solution would work for either of you 2

[FRex]

I tried and with Flash installed it doesn't happen. Disable yours in the plugins page and it probably will happen to you too. as in: playing of HTML5 under VLC player doesn't happen when FlashStopper and Flash are both installed and enabled.

[Sonic0170]

its the same with flash disabled for me, html5 player loads by default and flashstopper prevents autoplay, if you look at the plugin page the author specifically states that it works for youtube html5

[Sonic0170]

flashstopper doesnt have the specific click to play icon that flashblock does/did on youtube, it instead disables autoplay

[jackun]

Since I don't feel like dicking around with the script whole weekend I got a bit invasive and just disabled whole video element creation from createElement. Seemed to work kinda.

Cont. from #67: yep 61.11 fails to remove youtube player too.

[altunyurt]

Youtube player is still not removed completely on ff39 beta. None of the versions work since https://github.com/jackun/VLCTube/commit/96f4ad5e1e9ccf11ef5b8014ae303b822aec4714 , older ones work.

[jackun]

That's weird. How old version?

[altunyurt]

Even 60.0 works, I did not check for others. The last working one is https://github.com/jackun/VLCTube/commit/d635f02699f32f0568d9f844e620e8f2d519eb23 . Any commits after that one fails to remove youtube player.

I've also tried it with firefox developer edition(v40a.02), which has a clear history and cookie cache. It also fails with dev. ed too.

[jackun]

Tried 41, something weird like GM doesn't even run it. Just throws unreachable code errors. E: after 3 or 4 reloads it finally loaded EE: single console.log line in init delays code execution enough that it won't get replaced by flash..or something...oh yeah >_>

[jackun]

@altunyurt how's this?

[altunyurt]

@jackun player is not removed and seeing these in the console:

"Hijacked createElement:" "video" watch:10:4

"video seems to be unavailable" watch:3882:4

VLC player first shows up, but then youtube player takes over. This happens with all since 61.9

I don't have flash in my system, this is what i get even though I've enabled html5 player in my profile

[jackun]

@altunyurt ok, so then if that video element removing code is not injected, works?

[altunyurt]

Yes the last one seems to work. I'll try a couple of videos.

[altunyurt]

@jackun works seamlessly, thank you.
