[Platform_Windows]Slow motion playback
Problem Description: On the latest versions of Chrome, Opera and Internet explorer with Flash 11.2 installed for all browsers, higher quality YouTube videos and most videos on websites besides YouTube will play with the video in slow motion (smoothly though) and skip chunks of consecutive frames while the audio plays fine. The video and audio are not synced together, and the video lags behind the audio. This problem did not occur with Flash player 11.1, where higher quality video would have a lower frame rate but the video and audio would be synced. I noticed that with Flash Player 11.2, as I mentioned, the slow motion effect doesn't drop any frames, and thus videos that used to be choppy with 11.1 now are smooth in 11.2, besides the regular frame jumping. If the slow motion and jumping effects can be solved this may be a break through in getting older computers to play higher quality video smoothly.
Steps to Reproduce: Configuration: Athlon XP 3000+, 1GB DDR PC 2100 RAM, Radeon X1950 Pro AGP 512MB Video Card, Windows XP Professional 32-bit, Use the latest Flash Player and the latest version of Chrome, Opera or Internet Explorer. View a video at 720p or 1080p on YouTube.
Actual Result:Video is in slow motion, out of sync with the audio, and appears to jump chunks of frames as if to try and keep up with the audio (but doesn't very well if at all).
Expected Result: The video and audio should be synced, but with this processor I would expect a lower frame rate, depending on how intense the video is. At 1080p, YouTube videos barely even went past 2 FPS with Flash 11.1. With Flash 11.2, I get the same "slomo" performance with 1080p as I do with 720p, strangely enough.
Any Workarounds: I set the quality down to 480p to maintain a sufficient video/audio sync.

Impossible to watch video relating to my work. Productivity stopped. Need to fix this now! Whatever it is. Why not roll back and then work on it?

This is THE FIRST TIME I have ever taken the time to rant to a company about an online product or bug. This latest version of flash is driving me nuts! My wife and I used to enjoy pulling up shows off Hulu or YouTube as part of our bedtime routine, and it is now a total exercise in frustration. You have GOT to fix this!!! I spentall day today uninstalling and reinstalling a mish-mash of software trying to "fix" my computer, and then I get on her and see all these people with the same issue and you guys are talking about this problem NOT being a priority to fix... are you KIDDING ME!?! You do realize that for every person who knows how to get onto your website and leave comments and complain, there are probably a thousand people who just get pissed, give up, and mutter about how they hate your product now. That is NOT good for business.
And,here's another thought, send out an "update" that allows users to revert back to a past version of flash while we wait for the fix. THAT should be hard at all!
If I was Adobe's CEO I would fire whoever worked on this version of flash and make the fix-it team work non-stop until this issue is fixed... I'm not kidding, this is a product killing and company-reputation destroying problem. You guys think you're bullet-proof and that this issue isn't a priority? Yeah right, tell that to Lehman Brothers... Fix it, fix it, fix it, fix it... like the SNL skit, FIX IT!!!

TV programmes are becoming unwatchable online on Channel 4 (http://www.channel4.com/programmes/4od), and ITV Player (http://www.itv.com/itvplayer/), though Channel 5 (http://www.channel5.com/demand5) seems to be mostly unaffected: perhaps they use lower quality? BBC programmes mostly play reasonably well online, but many programmes downloaded for their iPlayer Desktop app, which uses Adobe Air, are so jerky that it's impossible to follow what's happening.

Same problem. Facebook videos terribly slow and out of sync. Most other websites slow as well. Please fix!
9:02:53 PM GMT+00:00 May 7, 2012
This bug is terrible, I used to get my daily mood refresh watching my favorite videos at Youtube but now I get the same problems as reported. I get more of this issue using Firefox 12 than when I use Internet Explorer 8.
8:53:34 AM GMT+00:00 May 6, 2012
This is a must fix.
This issue is horrible on live streams.
This needs to be fixed real soon!
7:01:15 PM GMT+00:00 May 2, 2012
Same issues! Cannot watch anything over 10 to 15 minutes with out it starting to bog down. It is useless to try to fix on my own because I don't know what the freaking issue is!
1:42:03 PM GMT+00:00 Apr 29, 2012
same problem. plzzzzzz fix
2:20:52 PM GMT+00:00 Apr 28, 2012
How long do people have to complain about the audio/video sync issues before you F***ING do something about it?! How about OFFERING THE OLDER VERSION ON YOUR DAMN SITE!

Same problem here.
Version 11.1 worked fine. Version 11.2 plays videos like in slow motion. What is interesting, when in full screen videos play fine!

Video's gone slow after update
10:33:47 AM GMT+00:00 Apr 16, 2012
I have the same problem. Flash movies used to work fine. Now only Youtube works well. All other movies are slow/out-of-sync. If I pause a movie the frames catch up with the sound for like a second behind a the darkend pause screen.

I have been having same issues on my machine (XP) since installing new build. Audio OK, video is in slow motion.
12:02:37 PM GMT+00:00 Apr 13, 2012
Similar problem as everyone else since the latest update. Slow motion playback and then will jump forward. Youtube seems to be the worst for me.

I'm having the same problem, after updating to the latest flash player, video/audio out of sync. I even updated my drivers and used the uninstall/reinstall player. But it didn't help. I tried to go back and install an older version of the flash player, but it wouldn't let me. It made me quit the install and offered me the latest version which I do not want.
11:35:05 AM GMT+00:00 Apr 12, 2012
After update to latest Flash, many web videos are slow refresh when at full screen.
8:14:11 PM GMT+00:00 Apr 11, 2012
As of April 2012, the player renders video really slow. Audio okay. Hint: Not everyone has Windows 7. Test bug code on XP to verify. A fix is needed soon, as this is really embarrassing for "Flash".

I have definitely experienced this issue for Flash Player 11.2 on my Windows 7 PC which uses AMD/ATI Radeon HD 4550 video card which supports H.264 video decoding. There's definitely a lot of lag in the video playback with dropped frames causing slow playback and video and audio sometimes are not in sync. Once I uninstalled 11.2 and installed flash player 11.1, the video played fine. I'm assuming this is a problem with the multi-threaded video decoding introduced in Flash Player 11.2, since threads are not always synchronized easily and perfectly.
this video lag with slow motion playback and dropping frames with Adobe Flash Player 11.2 is any flash player supported program on Windows 7, Windows Vista, Windows XP and is seen on any browser (IE, Firefox, Chrome, etc.). A good test would be play a full episode of any TV program on hulu.com and you'll see dropped frames and slow motion playback frequently. Flash player 11.1 doesn't have this problem.

Experiencing the same issue after updating to flash 11.
11:49:08 PM GMT+00:00 Apr 9, 2012
Having the same issues when playing video and on some games.
8:05:58 PM GMT+00:00 Apr 9, 2012
I am having the same issue, ever since I've upgraded to the latest flash player.
I've tried every possible solution. This is most likely adobe's issue. Hopefully it
can get sorted out pretty soon.
