Safari :: HTML5 Not Playing On Youtube
Apr 23, 2012
I'm having some YouTube trouble. When I play a video on YT, Little Snitch prompts me for "url..." at least twice before playing the video. But the video plays choppy until the entire video is buffered, and after playing about 25% it drifts out of sync anywhere from a half second to two or three seconds. It's really bad. Embedded videos on message boards etc play flawlessly.
Last night I got the 'No HTML5' message that others have been getting (as seen here) which kind of narrowed it down for me as an HTML5 issue. I am part of the HTML5 test group on YT but what made Safari suddenly stop dealing with YT's HTML5 is a proper manner?
I was one of the guys hit with the Flashback, could that have been a factor? I only noticed the problem after the two Safari updates from two weeks ago.
Info:Safari, Mac OS X (10.7.3)

i've been testing youtube's html5 beta on my aluminum macbook, 2,4ghz, 2gb ram, nvidia 6400m, OSX 10.5.8 after reading everywhere that it was less resource intensive than flash video, in fact, most of the things i've read said it was a huge performance boost. Nevertheless, after checking activity monitor I get Youtube with html5, around 95.0 CPU usage Youtube with flash video, around 65.0 CPU usage. So, whats the problem with my mac?? why do i get this results when lots of people are saying they get around 15% cpu usage with youtube html5 an safari 4?

How do I activate HTML5 to watch Youtube video's WITHOUT using Flash ? I have tried to find an answer but am unable to. I would prefer NOT to need to download and/or use Flash as I have read and heard that this can create security concerns on my mac. I am ABLE to play the same videos on my iPad though ( I know the iPad does not have Flash ) When I try to play the videos on my mac I get a message stating: But on my iPad, I AM able to play the SAME video.

How do you download videos from the HTML5 video player in YouTube? In the flash version it was sufficient to type alt-cmd-a to bring forth the activity window, then locate the .flv file in progress and double click it to start downloading to the local hard drive.
Now Safari (v5.0) does not seem able to do the same with the HTML5 videos. I imagine that there is maybe dedicated software for this, but I would like to know if there is a workaround with the Safari built-in functions.

I've found recently that when I'm watching a video on youtube through safari the video will suddenly stop around halfway into it. I end up having to watch it using another browser. This only happens with Safari.

Completed the Safari 5.1.4 update late last night and since then when trying to use youtube. Videos will play sometimes. Other times they will play but I have no control over volume, search bar, play buttons and the like. Also the biggest issue I am having is the like, share, add and other buttons don't work.

Recently I've noticed that my macbook pro is having a very hard time on youtube. The video player goes black but the audio continues. It freezes my computer. The video will sometimes play if I stop and reload the page multiple times in succession. I have a mid 2009 macbook pro running OSX lion 10.7.3

Since the new Air ships without Flash, this is a good time to mention these alternatives for Youtube videos. These extensions use HTML5 to play all Youtube videos, without gobbling up your battery like a buffet. Safari users [URL:...] Chrome users [URL:...]

Yesterdday 10.7.3 was released with new Safari and there is still NO fix for the Full Screen Sleep issue with HTML5 Video, whats wrong with you Apple, this bug is since Lion released with Safari,5.1 now 3 Versions later this small bug is still not fixed, but already known, i dont want to use Caffeine or such stuff, while Apple suggests the Web to use HTML5 why is the support for basic Features so bad?

Apple on Monday released Safari 5, the latest version of its desktop Web browser, with a 30 percent performance increase, the addition of Bing search and secure sandboxed extensions, as well as support for more than a dozen new HTML5 technologies. The update is available for download from Apple's website or via Software Update on Mac OS X. Safari 5 is a 39.1MB update. "Safari continues to lead the pack in performance, innovation and standards support," said Philip Schiller, Apple's senior vice president of Worldwide Product Marketing. "Safari now runs on over 200 million devices worldwide and its open source WebKit engine runs on over 500 million devices." Available for both Mac and Windows, Safari 5 includes improved developer tools and supports a number of new HTML5 technologies that allow developers to create rich, dynamic websites. The latest version of Apple's Web browser also includes Safari Reader, which makes it easy to read single and multi-page articles on the web by presenting them in a new, scrollable view without any additional content or clutter. When Safari 5 detects an article, users can click on the Reader icon in the Smart Address Field to display the entire article for clear, uninterrupted reading with options to enlarge, print or send via email. Powered by the Nitro JavaScript engine, Apple said Safari 5 on the Mac runs JavaScript 30 percent faster than Safari 4, three percent faster than Chrome 5.0, and over twice as fast as Firefox 3.6. Safari 5 loads new pages faster using Domain Name System (DNS) prefetching, and improves the caching of previously viewed pages to return to them more quickly.
Safari 5 adds more than a dozen powerful HTML5 features that allow web developers to create media-rich experiences, including full screen playback and closed captions for HTML5 video. Other new HTML5 features in Safari 5 include HTML5 Geolocation, HTML5 sectioning elements, HTML5 draggable attribute, HTML5 forms validation, HTML5 Ruby, HTML5 AJAX History, EventSource and WebSocket. The new, free Safari Developer Program allows developers to customize and enhance Safari 5 with extensions based on standard web technologies like HTML5, CSS3 and JavaScript. The Extension Builder, new in Safari 5, simplifies the development, installation and packaging of extensions. For enhanced security and stability, Safari Extensions are sandboxed, signed with a digital certificate from Apple and run solely in the browser. The details match a support document published over the weekend that suggested the release of Safari 5 for Mac and Windows was imminent.[ View this article at AppleInsider.com ]

Suddenly Safari either is very slow to load or doesn't load some pages at all. I have tracked it down to be pages containing html5 canvas element.
This happens only on iMac and Macbook Air. It doesn't happen on iPad nor on Safari on a Pc. It will happen on the Mac computer both when the pages are out on the internet and when the pages ar locally stored. It's driving me absolutely mad!
I've tried emptying cache both through Safari menu and by removing Safari's Cache.db, I've reset Safari preferences, restarted, and changed DNS to Open DNS (though it seems strange it should be an issue since the problem also occurs when I run the site on localhost). Â
If I open the page directly entering the url in the adressbar it works fine, it is when I try to access it from a link on another page on the site it doesn't load. If I press reload it will load fine. The link from other pages can be either an html <a href="url"> tag or javascript window.location or window.location.href neither works. The weird thing is it worked fine until just yesterday. And it works fine on every other machine except the Macintoshes.

My iMac has suddenly just stopped playing the videos in YouTube. Up until today I have been watching them no problem, now every single one i have clicked on says 'This video is currently unavailable'. However I can watch them over the same wifi connection on my iPhone4 no problem. I havent downloaded any new software or been on any sites other than Facebook, so can't imagine whats up with it. Please help I've only has it 5 days.

On Youtube there used to be a Subscription bar that would have all the recent video's by the people you have subscribed to in and you could skip to the next video in your subscription etc. Now it seems to have gone for me though and I don't see any way for skipping to the next video in your subscription without going back and clicking on subscriptions then choosing the video. Is it the same for everybody else or has anyone still got the subscription bar there?

Since yesterday, Youtube hasn't been working for me when I use Safari.
If I click on a video, the comments and everything will load, but the spot where the video itself should be playing is just a black screen. Researching this problem, it seems that it's usually a firefox issue, but I'm having it on Safari.
Youtube is working on Firefox, so it's not just Youtube being down or something. Also, I can't see embedded videos from Youtube on forums or anything.
Things I've tried and have failed:
- Resetting Safari (clearing cookies/cache)
- Logging out of Youtube
- Resetting my computer
- Turning off my ad blocker
- Changing my I.P. (probably stupid, but just in case I got super banned from youtube somehow)

Since I've upgraded to Safari 5.1.5 YouTube videos take forever to load, or never load at all.I do not see this problem in Chrome or Firefox.I've tried deleting my Flash Cookies (read online that it could help), but it hasn't changed anything.Anyone have ideas as to what's preventing YouTube videos from loading quickly as they have done in the past?I like Safari, and hope to continue using it; but at the moment it's simply unusable for my needs.

So I rebooted my Mac after installing some software updates. I then go to YouTube... but there is a problem, it looks funny. I can't watch any videos because it says "Hello, either you have JavaScript shut off or you don't have the latest version of Flash Player Installed"
1. I tried installing Flash again, nothing
2. Checked Javascript, same thing happened.
Firefox works well I guess.
