Yosemite 10.10.1 causing Safari not to play YouTube videos...

My Youtube will now play videos...about an hour ago i was at home when i found out the issue,pretty sad about it..

Now i am at work,,i went again to the check youtube,,,hola..by Gods grace,,its working now..

I did not do anything,,,i just turned off my Macbook Pro 2012 13 in,then went to office,,,then power on the MBP,,now youtube works normally.

Using Yosemite update,,,

same problem here, impossible to play videos like a normal human being

SOLVED!!!!

After tying many methods, changing user agent was working but not what I wanted. (10h of work to solve this!)

I have experimented with many older versions of flash, but finally I found the one version that doen not cause any problems.

how I did that? stumbled upon a 9to5mac article ant tried the version mentioned there and it worked!!!!

so:

Uninstall flash. then install flash 14.0.0.145.

works flawless now!

No need to do anything at all. You can play Youtube video with no problems now. I guess that Youtube just sorted this issue themselves.

Actually I still had the problem until the install of flash14 30minutes ago. so... I won't upgrade any more!

Just checked once more. No problems whatsoever. Can see all videos on Youtube with no flaws. I have the latest version 15.0.0.223 installed. May be your OS X system or Mac itself is faulty.

Just as a comment. Flash is a power hog. A big drag on battery and CPU which is particularly onerous for laptop users off their power brick. That being said, one does not need Flash to view YouTube video. That's why one can watch Youtube on one's iPhone, video is delivered HTLM5. Chrome browser contains a Flash component. One need not have Flash installed to see view Flash video in Chrome. I don't have flash installed on my MBP. If I run across content which requires Flash, I launch Chrome. We need HTLM5 Anarchy...Job's said as much. Not sure if one still has to opt in to HTLM5, but your can go here to to sign up.

All OK now. I guess someone did some update.

Very bad advice! Older versions of Flash are riddled with security flaws. Any user should always be using the latest version. Secondly, this WAS NOT a Flash player issue. It was a HTML5 player issue which Google (YouTube’s owner) has now apparently resolved.

1. This was NOT an OS X Yosemite 10.10.1 issue

2. This was NOT a Safari 8.0 issue

3. This was NOT an Apple issue

4. This WAS a YouTube issue which has now been fixed. End of story.

Today no problems at all, perhaps google sorted it out.

You might be right. but at the time of the problem this solution solved my issues. strange as it might be.

It wasn't my first bad experience with a flash update, and such a big issue I wasn't expecting form google or youtube.

now it works with the latest version.

Downgrade of Flash Player definitely did not solve your problem, don't be so stubborn, the problem was solved by YouTube and it was just coincidence that your Safari started to play videos after "sorting" Flash Player.

I can bet, if you uninstall Flash Player right now or even update it to the latest version, your Safari will keep playing videos on YouTube. IT IS SORTED BY GOOGLE, not you, buy installing old, vulnerable version of Flash Player on your Mac.

Why do people ignore previous posts when they decide to comment?

Same problem here but mostly with my Comcast homepage video. I'm just wondering after all these people complaining of video problems why we haven't had one Apple representative intervene to give us the solution?
