YouTube videos won't run

Suddenly, YouTube videos won't run. Instead of the video you see "You need to upgrade your Adobe Flash Player". Followed the link and installed the upgrade but problem persists. Starting with add-ons disabled doesn't help. ???

Make sure that your firewall isn't blocking the plugin-container process.

Video won't run. telling me to update flash player. click on update for mac won't load?

video won't run, telling me to update flash player, click on update for mac won't update. do i need to load flash player and is it ok for mac?

Yes, it's fine for your Mac ...
Most sites such as YouTube require the Flash plugin.
Flash isn't a player per se, but a plugin.
Sometimes uninstalling the current plugin then reinstalling new can help.
Troubleshoot Flash Player | Mac OS
Make sure and uninstall the old plugin first then restart your Mac.
If you use Safari to view videos, from the Safari menu bar click Safari > Empty Cache
Now try a video.

Since upgrading to Lion, YouTube videos won't play

A couple of weeks ago I decided to update from Snow Leopard to Lion. I thought that would entitle me to free Mountain Lion Updates, since Apple had already announced the launch date, but it seems that isn't the case, which is odd.
In any case, I've been frustrated because ever since the OS update, a lot of YouTube content won't run. Most videos play, but a surprising number show a never-ending circular buffer icon. I have a 20Mbps Internet connection on a Mac Pro with 12Gb of RAM, so this behavior doesn't make sense. Vimeo videos play fine.
I rebooted, zapped the PRAM and tried other fixes without success. I would like to reset the video pref or other configuration files to see if that will help, but I'm not sure which files to delete. Does anyone know what steps I can take?

Hi,
Have you disable the adobe flash accerlator? or how about your wifi setting? is it a WPA? If yes, changed to WEP.

When I am on a Youtube video that is running and I want to switch to another tab, the Ctrl+ tab number does not work, is that intended functionality?

When I am on a Youtube video that is running and I want to switch to another tab, the Ctrl+<tab number> does not work, is that intended functionality?

This can happen when the video player (Flash plugin) has the focus.
In that case the plugin consumes all the key presses.
You will have to click with the mouse elsewhere on the page or in the user interface to make keyboard shortcuts work.

Youtube videos do not run on Safari 7.0.5

After new OS X update 10.9.4, Youtube videos do not run on Safari 7.0.5. It always give error "an error occurred, please try later. LEARN MORE". While I can watch the video using Google Chrome Browser on Mac.
I have tried resetting Safari, opted out of Google HTML5 player trial as well. I also updated Adobe Flash Player but nothing work. Please help me run Youtube videos on safari again. Thank you.

It should work on v10.9.4 and Safari 7.0.5 ...
Open System Preferences > Flash Player then select the Advanced tab.
Click Delete All under Browsing Data and Settings
Then from your Safari menu bar click Safari > Preferences then select the Privacy tab.
Click: Remove All Website Data
Then delete the Safari cache.
Open a Finder window. From the Finder menu bar click Go > Go to Folder
Type or copy paste the following
~/Library/Caches/com.apple.Safari/Cache.db
Click Go then move the Cache.db file to the Trash.
Quit and relaunch Safari to test.
If nothing above helped, troubleshoot Safari extensions.
From the Safari menu bar click Safari > Preferences then select the Extensions tab. Turn that OFF, quit and relaunch Safari to test.
If that helped, turn one extension on then quit and relaunch Safari to test until you find the incompatible extension then click uninstall.

Certain youtube videos won't play in Firefox

Firefox 20.0.1, windows 7, flashplayer up to date.
Certain youtube videos won't play. The advert beforehand plays, and then the video just displays a black screen, no loading, trying to skip to a later time in the video doesn't work. It seems to be certain youtube users whose videos won't play, users whose videos I was able to watch only yesterday. The featured video on the user's channel is watchable, but not when opened separately.
IE won't show the affected videos either.

In addition to these symptoms, I've noticed that I can view these troubled videos on my cellphone just fine, but neither my XP or Win7 machine, which have all software updated can view. So if it was on youtubes side, it wouldn't work on my phone either.

My youtube videos are only running for a few seconds, then stop. Is this an issue with my macbook?

Web page videos won't run

I have a brand new 27" iMac. When I try to run videos from the Yahoo web page or You Tube, nothing happens. Video won't run. However, when I go to the Apple web page, I can run the Apple videos without any problems.

Chances are very good it's an Adobe Flash issue. Apple no longer ships new computers with Flash on it, the solution is easy though navigate to:
http://get.adobe.com/flashplayer/otherversions/ then download it and install.
BTW you also have 90 days of free AppleCare service, you can call them and they will coach you through any other issues you're running into. You can find the phone number in your manual.

Videos won't run on certain sites

Why won't videos run on the O'Reilly Factor web site but will on the FoxNews site. Same with On the Record? I have uninstalled and reinstalled Flash Player several times. Deleted cookies and cache several times. FireFox won't run them. The Guest User used to run them but now won't. YouTube works great.

Ok, point given on the ad block plus, however all three systems have ad blockers installed.
Ad Block Plus (Firefox Only)
and Kaspersky Internet Security 2012 (Firefox & IE9)
both however were disabled on the two computers that are affected, to resolve the issue, I'll re-examine differences between the working and non-working computers.
The Kaspersky addon that blocks it hasn't worked/been updated to work with firefox 10/11
The computer that isn't affected has ad block plus enabled. and kaspersky is again disabled due to incompatability
All computers have 11.1.102.55+ installed

Every other Youtube video won't play

I am using Chrome so I don't know if this is the appropriate place to ask for help. Every other youtube video or other video I try to play will not load. I just get this constant spinning circle of white dots. I did see that I had accidently downloaded the extension for chrome flashplayer so it was competing with apples flashplayer. However, I unselected Chromes version of flashplayer and it did not fix the problem. Does anyone have any ideas on what may be wrong?


right click on the videos and they say Adobe Flash so i assume they are not in HTML5 but i am not sure. 
What does it say when you go to https://www.youtube.com/html5? 
Mine says The default player is currently used. which of course means I'm using Flash and not the HTML5 player.
Can you try to start Firefox in Safe Mode to see if Firefox works properly with no error? You can start Firefox in Safe Mode below:
*'''Windows/Mac''': Go to Help > Restart with add-ons disabled
*'''Linux''': Run ''firefox -safe-mode'' in the Terminal/Konsole
If Firefox opens up fine with no problems, it's probably one of your extensions that's causing the issue. You can re-enable your add-ons one by one until you find the one that causes the issue upon being re-enabled.

Help me please, games crash on launch, youtube videos won't play.

Whenever i start up sound blaster cinema it just crashes, it will be fine for about 10 seconds, then it just crashes, it will usually freeze up everything when it crashes only thing i can do is move my cursor around, it will unfreeze after 10 seconds or so as well.
I have tried to update sound blaster cinema but there are not updates available.
It would usually go back to normal after a shutdown or a restart but this time it wasn't having any of it.
Can anyone suggest anything that i couldn't think of?
The crashing first started a month+ ago, but today when I was playing L4D2 a boomer explosion crashed L4D2 and sound blaster cinema simultaneously and now sound blaster cinema won't stop crashing after launch.
(Edit)
I can't launch any games, i try to play the game osu! and it launches normally except the screen turns black and then it crashes. i try to launch steam and login but the login menu wont pop
I can't even play a youtube video, the background of the video will show but the video won't play, it's not buffering but the video is loading.
windows media player won't launch as well, videos on my computer will not play at all.

(FIXED)
I went and downloaded thee intel(R) driver update utility 2.0 went to find drivers and then to auto detect and updated my drivers.
This is the driver that helped me. vvvv
( Iris, irispro, and hd graphics driver for windows*7/8/8.1 version 15.36.19.64.41.70 )
Sound blaster cinema doesn't crash on launch anymore, neither does my game osu! and youtube videos now play.

YouTube videos won't play on Google Chrome anymore!

I noticed that today Google Chrome won't play YouTube videos anymore, even in HTML5. If I try to watch a YouTube video, the buffer bar appears for a split second, but then it vanishes and the loading takes forever! I'm using Google Chrome 33 on Windows 8. Is there some way to fix this? Here's a video I was trying to watch.
Never mind. It seems that embedded YouTube videos work fine here, but not on the YouTube site!

Hi!
I am having a similiar issue since the last update. But contradictory to what you said, i am able to see only videos on Youtube site and not the embedded ones.
Hope it gets fixed soon, for this is very annoying
Flash player: 12.0.0.70
Chrome: 33.0.1750.117
Cheers!

Certain video won't run.

The videos that won't run are on the top portion of the msn.com home page. (See screen shot).
The dotted circle continues to run and run and run....., but the video doesn't play. The other videos on the page run well. I have tried to run them on Lion (10.7.3) and Snow Leopard (10.6.8), but they won't run on either. I have tried to run on both Firefox 11.0 and Safari 5.1.5. Nothing! I have the latest Flash Player, Silverlight, and Quicktime Player installed. These videos DO run on my Windows Vista laptop, so the problem lies somewhere on my Mac Pro. Could it have anything to do with the graphics card (NVIDIA GeForce GT 120 512 MB)?
Does anyone know where the problem lies, and of any fix?
Thanks.

I'm sorry. I hope I don't sound too clueless, but when you say "account," to what are you referring? Setting up a new user account? I am running as the Admin. with root access, and the only user on this machine.
I deleted the FlashPlayer .plist file, but when I then tried to view the videos, the problem was still there.
Is there any way to identify a corrupted file? I've also repaired the the permissions on both drives, but that wasn't the answer either. Would a corrupted file be found and repaired if I ran disk utility Repair Disk? Is there an app. that can locate and repair a corrupted file?
As you can see, I'm blindly flailing around just trying to locate the problem. I appreciate your brainstorming this with me.

Certain Youtube Videos won't load anywhere.

Hello everyone.
Since a few days (I guess) I've encountered major problems with Youtube. Certain Videos won't load in Firefox. They just won't - they stay at the 0:00 mark and never move. I can see the first frame and I can even scroll through the frames, but it will never play. That isn't the case for every Youtube video, though. Most of them work fine, but a few of them have this problem. And the number of videos having this problem is raising fast. Even videos I could watch perfectly fine before simply won't work anymore.
And really - I am at my wit's end. I've tried every fix known to man (as far as I know). Cleared cache, cleared cookies, updated Flash, Firefox and every other program or plugin I know of, updated drivers, un- and reinstalled both Flash and Firefox completely, changing Flash's settings - but nothing works. These particular videos just never want to move.
And the funny thing is: It's is not even just a Firefox problem. It doesn't work on any other browser of mine. It doesn't even work on my other two computers. Not even on my Smartphone!! Once a video encountered this problem it is GONE FOREVER. I have no possibility to watch it anywhere. But it can't be the video. Because ~120.000 people have already watched it without having any problems.
Yeah, so why am I asking this in the Firefox forum? It's because Firefox was the browser which started it all and if Youtube would just work for Firefox - I'd be fine with that.
So if anybody can help me with this I'd be very, very grateful!
Regards, Megamag

After re-installing the software, did you perform a "hard reboot" on the machine? It could be that although you installed the updated version of Adobe flash player, the computer may not recognize the updated software until a cold reboot has been performed. Here is a link to a website I went to find this information:
[[Can't play Online Videos--Here's what to do|http://www.compukiss.com/videos/cant-play-online-videos-heres-what-to-do.html]]
Here is Adobe's website if you want to check to see if your adobe's Flash Player is updated:
http://get.adobe.com/flashplayer/
Performing a cold reboot on your machine will reset the adapters and clear out the memory which will also enable the PC to recognize the new software installed. To perform a cold reboot on your machine:
1.) Go to the "Start Button" and press ''Shut Down."
2.) If you have a desktop, unplug the power cord and leave off for 10 seconds. If you have a laptop, remove power supply and battery for 10 seconds. (I leave mine off for at least 20 to 40 seconds myself.)
3.) Re-install the battery(laptop) and plug in the power cord.
4.) Boot the machine on.
Here are the links I used for this information:
http://support.microsoft.com/kb/102228
http://www.ehow.com/how_2292987_cold-boot-computer.html
If this method doesn't work, then I would recommend going to your manufacturer's website and see if they can't help you resolve this issue with your videos not playing on your computer.

Non-flash youtube videos won't play on safari

Using the desktop version of youtube on safari - not the app.
The page loads, the screen is blank with the "Play" arrow button in the middle but then the video won't start/load/play. If I navigate away from the page, it will briefly show the first frame and then it disappears again. These are videos that were working absolutely fine up to last night with iOS 5. I have since done hard reset and installed iOS 5.0.1 but no luck. Any ideas what might be happening?
Thanks in advance

Using the desktop version of youtube on safari - not the app.
Swipe left on your Home screen then type: Youtube in the search field.
The app looks like this > It comes pre installed on the iPad so there's no way to delete it.
