Safari will not play Youtube videos!!!

The following answer worked for me 1YEAR after it was originally posted! It was the youtube html5 trial that I never knew I was a part of. I have tried so many suggestions from this discussion and others and nothing worked until I tried this SUPER SIMPLE fix. THANK YOU leejbarker32!!!! I have been going crazy over this for months!

Ok, I'll stop blaming flash and either blame Apple or YouTube...

I went to http://www.youtube.com/html5 and found that I was part of the HTML5 trial for YouTube and that YouTube videos should be playing via HTML5 and not Flash.

I left the HTML5 trial so that the video were being played by nasty old Flash... Guess what, it works.

Videos are now playing normally using Flash.

My suggestion is go to http://www.youtube.com/html5 and see if you are part of the HTML5 trial also, if you are, leave the trial and see how you go.

Hi! I tried doing both solutions: disabling my html 5 and joining youtube extension of @jon corry, still did not work. Any other solutions? Thank you!

I did this on Jan 1, 2013, and I've had no problems since:

Go to Safari/Preferences/Privacy and click the Cookies and other website data "Details..." button. Delete both the youtube-nocookie.com and the youtube.com cookies, quit and restart Safari.

Bruce, John, whomever, my wrinkles are these:

1. Neither Safari, Chrome nor Firefox play YouTube video on my mid-2009 Macbook Pro 3.06 GHz Core 2 Duo laptop w/8 gb RAM and running Mountain Lion 10.8.3 (nor, as it happens, in my iMac desktop). I desperately need YouTube videos for my classes

2. I most often get the empty black box in Safari; in Chrome or Firefox, I often get the "unable to play/Learn More" error dialog. The video seems to be triggered because the Pause symbol shows, but no video ensues

3. I have updated Flash until my eyes bleed; deleted it, reinstalled it, ad nauseum. No joy

4. My Safari is not in 32-bit mode

5. I have dumped Trash, cookies, everything. No joy

6. I was not in the HTML5 Trial, but I opted in, opted out, and shook it all about. No joy

7. I have deselected and selected hardware acceleration in Settings. No joy

I have no idea why none of these fine solutions, so successful for others (to my increasing dismay ...) are not effective for me.

That worked one time. The second video I tried to play returned the same error dialog. Any ideas?

Funny thing: starting this week, I was also UNABLE to watch YouTube videos. I could see the whole YouTube page(s) but I would just get a blackout video playback screen instead with no controls either. So I visited the above link as suggested while noticing I was NOT signed in the html5 try out program. So, I DID join the program and now I can watch the videos fine.

I am on a MacBook (2010), Snow Leopard 10.6.8, using Safari 5.19.

When I try to use you tube the videos will not play. The screen in black with a fuzzy line through. I have updated the iPad and still the same problem. Any suggestions?

You are so, so hilarious. You made me laugh so hard.

Im with DCR on this one...

I have tried, to no avail, getting flash content to work from every angle. It will load the player, but certain swf files that are used for interactive content are loading Ad Nauseum. Granted my issues are more with swf files and how they are being read "hit-and-miss" via Safari (and even Chrome), the same rules apply. I believe we have a trifecta of problems occuring: with the browsers treatment of flash, the latest flash update (as per late January), and with the programs creating this flash conent that I am using for educational purposes. I did have (some) success with other web browsers (IE, Opera, and Firefox - kinda), but here's my gripe:

• I tried working on the program that publishes the flash content, re-exporting, re-uploading, and re-connecting to the content. No bagel.
• I tried working with the browsers that display this content, adjusting settings, clearing data, restarting, on all 5 major browsers. No bagel.
• I even tried working with my computer's settings to see if there was anything interfering with the flash content remotely. No bagel.

Now here I am trying to contact all the developers of their respective software (Articulate, Adobe, Apple, Google, even our site admin YourMembership). Need to find this solution or at least a workaround before all the students using this educational material turn into an angry mob lol

So, any solutions yet?

The year is 2014 and FLASH STILL DOES NOT WORK UNDER SAFARI...

wow - when is Apple ever going to figure this out???

SERIOUSLY? WHEN?

YouTube doesn't support Safari anymore for no reason.

Uninstall and Reinstall Adobe Flash Player: http://helpx.adobe.com/flash-player/kb/uninstall-flash-player-mac-os.html

I Didn't even know I was enrolled into an html5 trial, or how I even get out of it.

youtube videos just lag and freeze, on any browser, tried it on about 3 different iPads and all the same. Even the YouTube app is starting to be all out of sync with the sound.

All it took was disabling the "Click to Flash" extension I had loaded an hour ago. Now videos play. I'm getting to hate extensions of all kinds.

Well deleting the YT cookie seems to work.

-------

However what I did, i took the big broom and swept off the Safari cache completely, restarted Safari and voilá YT works now.

I had earlier installed the HTML5 player extension for Safari, but without clearing the cache and a restart it didn't help.

- So much for my penny in this thread.
