After installing Firefox addon YT becomes unusable. I can open page with video but there's no way to play the video nor i see any controls. I am using default options.

This is debug output.
And this is how i see the video 'frame'

I've tried installing latest userscript and that works just fine.

the extension is not working anymore (firefox 23 from Brazil)

The extension YoutubeCenter is incompatible with Iceweasel 18.0.1

Hello,

Disabled Dash don't work anymore, I tried reinstall and nothing. You know that?

thanks for extension

It would be convenient if, when rolling over a video thumbnail, the thumbnail would rotate through the three auto-generated thumbnails, making it easier to preview a video (especially in the case of videos with custom thumbnails).

As per the screenshot. This is after I've already visited YouTube more than once after which the welcome dialog should have already been disabled.

Using Safari Version 6.1 (8537.66) on OS X 10.8.5.

Make it possible for users to choose if they want to use the flash or HTML5 player by using an option in the YouTube Center settings.

YouTube Center should use the player api: writePlayer to change the player type.

Example for changing the player to HTML5:

api.writePlayer("html5");

Example for changing the player to flash:

api.writePlayer("flash");

Recently YouTube began showing "▶" when the player was playing a video. YouTube Center should make an option to remove this from the page title.

Just updated to the 2.0 Release, Thanks for the upgrade!

Unfortunately, the Disable Auto-Play isn't working for me in this version
And my options didn't carry over (But that's trivial)

It doesn't seem to matter how many times I save my settings, the "Thank you for installing YouTube Center" message always shows in embedded videos.

Change the top one to the bottom using a setting. This would be great for larger screens.

Videos don't buffer in their entirety after disabling dash playback in settings. The previous build didn't have this problem.

I was trying to watch a live video but there was no player, until I disabled the extension.

I use "Feather" to cut all the crap. It's basically just the nav bar, video, and description.

So, I have in my bookmark in firefox the link on youtube to go directly to my subscriptions (youtube.com/feed/subscriptions), until yesterday it was fine, but today the new videos of the channels I'm subscribed sometimes appear and sometimes they don't, I need to keep refreshing the page until I got the new videos to watch. How can I fix this issue? Also, I installed YouTubeCenter yesterday.

On each YouTube video, in the source code you can see the tags being listed inside a "meta keywords" HTML tag. These tags used to be listed after the description in the old layout, but after the update they were removed from there. Can you add them back in their place?

I've used YouTube HD Suite (I think that's the right name) months ago which also had these resolution thumbnails and since I sometimes listen to huge playlists (almost 200 videos) it used to file too many requests to youtube, which left me with entering a captcha almost every 3rd video.

It seems your script does not cause me to enter a captcha but it slows down the loading of the page only to find "Error!" and "Too many requests!" on video thumbnails.

I can think of a few ways to solve this:

1. Cache the data so you don't have to request it every time. This is a bummer for playlists with 200 videos so the cache should be about 240 entries long or similar.
2. Provide separate thumbnail options for playlists (or just make it the default with >50 videos in the list) where one could choose to only load data on mouseover when the thumbnail is in the playlist. This is because I still like to see the thumbnail info on related videos which are only about 15.
3. Don't load thumbnail info in playlists at all.

Btw, your solution for this is really awesome (regarding configurability and displaying), I like it a lot. Kudos.

Im on Firefox 24 at the moment but the same thing happened on FF 23.0.1 using YTC 2. I am unable to watch pop up embedded FLASH youube videos. HTML5 videos work just fine. I am able to watch videos with res on reddit which im guessing YTC doesn't handle.

Some people are experiencing that when prevent auto buffering is enabled that the preview is shown but the video is still playing. I'm currently investigating this issue. So if you have this issue you can go to http://userscripts.org/topics/128076 to read more about it.

I guess you remember the old days when the currently playing playlist used to show up at the bottom and you could access the next 3 videos immediately (on larger screens). Also it didn't cover valuable space of the video player and you could still watch a video while browsing for the next one.

What do you think about bringing that back (mostly manually coding I guess)?

We'd have to find a better solution for scrolling though, maybe a horizontal scrollbar and loading videos and thumbnails late/delayed could already help.

For some reason whenever I disable Dash Playback in the settings panel, it won't buffer the whole video anymore. It was working just fine last night. Do you guys think you can fix it?

I've just installed youtube center 2.0, and the settings cog doesn't appear. I've uninstalled and reinstalled, so that's hopefully not the problem. Screenshot attached.

It would be cool to have an option for the player size to automatically match the video quality (resolution), so if the video is 720p, the player width would grow to 720 pixels while a video that is only 480p would be displayed in a player with a width of 480 pixels.

By the way, thanks for the great userscript. It's really appreciated!

Thanks for the greatest addon!
Can i please have an option to always have the video player visible, even if i scroll down comments/suggested videos area.

Hi, awesome plugin thanks..

Version 1.34.0 installed.. when I click play on videos embedded in Google+ I see the following image:

The text says I need to configure the add-on.. but I've certainly already done that it works nicely.. I dont see the same behaviour on videos embedded in Reddit (for example)

Thank you for creating such a marvelous Chrome extension. I noticed that the embed feature isn't working on some websites, for example the videos embedded on Khan Academy website. This is one of the examples:
https://www.khanacademy.org/partner-content/stanford-medicine/tuberculosis/v/what-is-tb
The highest quality of video embedded is 720p but unfortunately, regardless of the settings set on Youtube Center's Embed Auto Resolution, it won't set the resolution to what I prefer, i.e. 720p or higher.
It works pretty well on some other websites, for instance:
http://www.androidpolice.com/2013/09/14/new-app-dynamic-keyboard-alters-key-sizes-as-you-type-now-available-in-free-and-pro-versions/

I hope you can look into this when you have a chance. Thanks!

Youtube Center 1.34.0
Chrome Windows x86_64 Version 30.0.1599.37 beta-m

For example:
*_Video only has up to 480p resolution
*_option is ticked
**Auto-Resolution is set at 720p

**switch resolution to 480p

Thanks for developing the best and only YT tool!

• We are unable to disable script for embed videos. "Enable Embeds" option doesn't work. Script work regardless of this option.
• "Enable Auto Resolution" option doesn't work. Quality is always changed to selected one.
• Dash Playback can't be disabled. While with the same video and quality it can be disabled on YT page.
• When "Prevent Auto-Play" is checked and "Prevent Auto-Buffering" is unchecked. Playback problems are quite common. Only audio is playing or even only progress bar is moving. We can see "null video decoding" in YT stats.

None of this bugs are present on youtube page. It's only on embeds.

I will provide logs and every other info if needed. But I think you will be able to reproduce those issues. I know I reported this on userscripts.org, but I think this is better place to do this :)

EDIT:

Would be great if we could force HTML5 also on embeds, but I think there is other open issue for that.

If you're using Scriptish for Firefox the Signature Decipher doesn't work.

A TypeError is thrown when the GM_xmlhttpRequest function is called to contact the javascript file on one of YouTube's assets domains. The GM_xmlhttpRequest function works perfectly when trying to contact userscripts.org.

There is no information about the TypeError, which was thrown.

When Page Centering and Resize are disabled, youtube ends up broken. It should result in a page that behaves like the default youtube page for layout and sizing. When changed to the large player while watching a playlist, the top bar is the correct size, but the video does not extend as far as it should.

Also, when resize is disabled, the youtube guide is not clickable which makes youtube unusable

When i try to watch this video with Youtube Center available the player will show a "This video is currently unavailable" error. Disabling youtube center will allow me to watch the video just fine.

Youtube center 1.34.0 and google chrome 29.0.1547.66 m

Here's the console output without youtube center:

I'm not sure if the option already there but I can't find it anywhere.

Youtube used to have this option where you can show all videos from the same uploader without leaving the page. It would be cool if we can have that back! Thanks

I'm seeing abnormally high CPU usage by Flash Player when I play a video with the extension enabled. When I disable it all is fine. (Is this caused by some option I set?)

I'm on OS X 10.7, Chrome 29.0.1547.62, YouTube Center 1.34.0.

Activity Monitor when playing back video with extension disabled:

When I enable it:

When on a channel and then selecting another channel from the bar on the right hand side (i.e. 'related channels' or favourited channels) the banner image at the top of the channel page does not update. The second channel still displays the banner image from the first channel.

When resizing is enabled, scroll bars appear and cover up the video player controls.

When resizing is disabled, only the vertical scroll bar is shown.

YouTube Center doesn't work on YouTube channel videos.

Let users a way to download Playlists.

On the YouTube home page and search pages the YouTube menu is visible on the right-hand side.

However, when you are watching a video the menu disappears completely and cannot be accessed.

Hi,
I found regression in 2864937 some embed videos doesn't load properly. Only black box is shown.

http://www.wykop.pl/wpis/4924149/ Click on [zobacz film z youtube.com] should load the video. Was working fine before 2864937

This happens only on this site. Generally embed videos works fine. You should be able to reproduce this easily, but if not I will provide more info :)

Hi,
It seems that for me, toggling DASH off does not have the desired effect, "If Dash Playback is turned off YouTube will load normally where you can pause the video and it will buffer to the end of the video and you can jump around in the video as much as you like.". Youtube still buffers in blocks, and pausing the video will not let it buffer to the end. I don't think it even caches the blocks that have already been buffered, although I may be incorrect in that.
I've also gone over the code (the Chrome extension) but wasn't able to find out the implementation of toggling this. Probably because I didn't understand most of the code anyway! Is it a parameter that is passed to the flash player?

Thanks for this awesome script/extension!

Hello,
I´d like to know why I can't watch videos with 1080p resolution anymore. Is it an bug in this application or it's a issue in my brownser? Thanks

I´ve just downloaded this app a few days ago, and I do not use nothing the I don't use any other complements besides this one, Firebug and AdBlock Plus, so I don't think its a incompatibility issue.

I use the Firefox version 23.0.1
Win8 64bits
YouTube Center 1.34.0

The "Recommended for you" video suggestions on the right hand side on view pages annoy the everliving crap out of me, due to it showing me videos I have absolutely no interest in watching, based on videos I watched a year ago or that my friends have watched or shown me whilst logged into my account. Any option to hide these would be great.

Something like:

var matches = document.querySelectorAll("span");
for(i = 0; i < matches.length; i++) {
    if(matches[i].innerHTML == "Recommended for you") {
        matches[i].parentNode.parentNode.removeChild(matches[i].parentNode);
    }
}

...I'd make a pull request but I can't make sense of what you got going on here.

Excellent userscript!

Please document "Shuffle" from UI > Video Thumbnail as I don't know what it does:

A search for "shuffle" turned up no usable results.
I love the extensive documentation you guys have for every option, it's just missing this one new item for me to be called perfect.

My settings got reset with the latest update:

No biggie, I went through and customized everything again.

A userscript, not an userscript:

As per the pronunciation of "user", the article in front of userscript needs to be "a", not "an". Example:
YouTube Center is an userscript designed to expand the functionality of YouTube. ✗
YouTube Center is a userscript designed to expand the functionality of YouTube. ✓

Can I please be a contributor for YouTube Center? I can help manage the wiki and stuff. And I'm very good with English too.

For some users the YouTube Center doesn't work on embed videos.

As you can see in the two photos, I have the latest YouTube Center build installed and enabled (it is the latest build, even though the version number says 1.34.0) but the settings cog won't appear.

Attempted to use beta version linked (in issue #15 ) but it 404ed.

When I click any of the related video, the video seems to be realigned to left side of the page and overlap with the guide links.

It appears that the realign to center fix is not applied on loading related video
