Symptoms: Click on a video, browser goes to that youtube page, get the little white dots going around in a circle on black background. White dots freeze, video starts playing, sound works OK, video stays black with the circle of white dots.
I un-installed Flash Player and re-installed 10.2 (IIRC). That seemed to help IE for a moment, but now the symptoms have returned.
We’re running AVG Anti-virus and it is up-to-date, so I don’t think it’s a virus.
Tried YouTube help but (aside from the Flash Player re-install) didn’t find anything helpful.
(the reason I didn’t immediately associate the symptoms with the changes I had made was because there had been an interval between the tweaking and the next time I happened to try watching online video).
Are you positive that the video in question hasn’t been blocked by youtube, or overwritten with a black one for some reason? Can a friend view this video? Can you view other videos?
I had the same problem a while back. It turned out to the result of a corrupted profile in my browser (Firefox). I uninstalled FF, making sure to tick the box to delete the profile/preferences, and did a clean install. I then finally got YT working again.
For the last couple of weeks, I get no video at all on the regular settings of YouTube, although sound comes through fine. (YouTube videos embedded elsewhere, or viewed on the creator’s channel, are totally normal.) Has YouTube changed their settings somehow?
Fear Itself - I think that Apollo’s tip was for those of us who got a blank white screen (with sound) on YouTube’s website, but could watch YouTube videos elsewhere. Or at least, that was my situation, until I took his/her advice.
My wife’s computer just now developed the same problem. Movie simply doesn’t load. The symptoms are the same in Firefox and Internet Explorer. It’s as if the computer has simply decided it doesn’t want to load anything from YouTube’s movie server.
She followed a tip online that fixed the problem to connect via https instead of http. For some bizarre reason this fixed the problem.
I’ve been crashing my Flash Player in Firefox for the last few weeks. I just tried the Apollo method and the vids appear to be working fine now. Thanks, Apollo!
The problem is that the latest Flash player has a lot of bugs in the updater. It seems to work perfectly well if you do a fresh install, but if you’ve used Flash before, it’s a roulette.
This is why I always recommend not to update Flash right away when they go to a new full version. I have yet to see a website require 10.1, let alone 10.2.
And, yes, the hardware acceleration in 10.2 is somewhat broken. I think it used to fall back to not accelerating if it wouldn’t work, but now it doesn’t, so you have to manually shut it off.
Finally, YouTube does their videos a little different than everyone else. On the actual website, they don’t directly embed the video, but stick it inside a container. That’s probably why some people are only having problems with YouTube, and not anywhere else.
BTW, there’s one more problem you can have with YouTube, but it would be hard to accidentally do. There’s an HTML5 version you can opt into, but it’s still in beta and thus has problems. I wouldn’t use it unless you just hated Flash. (I believe iPads either use their own program, or use it automatically.)
