Choppy Youtube video playback on Lollipop

Hi Guys,
I've just got a new Z3 with Lollipop pre-installed and found that YouTube playback via the default app is choppy/stuttery.
I tried factory resets/ updating the YouTube app/clearing cache/turning the x-reality engine on/off, but of no avail.
The videos play perfectly fine on my much older Xperia s, so pretty sure this not on the YouTube end.
Please advise.
Cheers.

Youtube works fine on my Z3 settings/apps /YouTube uninstall updates .

Youtube video playback choppy

I know this is a problem many others have had, but I couldn't find anything doing a search.
I did a clean install of Windows 7 Professional a few weeks ago and now I am having problems with video and audio playback when viewing imbedded youtube videos. I tried uninstalling Flash 10 and installed Flash 9 as I read somewhere this may be the culprit. However, this did not help.
I am wondering if it is a video card issue. I have download the Windows 7 drivers for the card, but that didn't help either. I never had this problem until I installed Windows 7. Any ideas on what I can do? Do I need to update (buy a new one) my video card? I am using a Dell Dimension 8400 with 3gb of RAM which is a few years old but still very serviceable. The video card is an ATI Radeon X300.
Thanks for your help.

Thanks for the reply.
Flash folder contents:
Flash10e.ocx

Sometimes when I open Quicken there is a problem with the sound. Quicken normally plays a short melody when it opens. However, since I started having this problem, the melody sometimes stutters like the youtube audio. Because of this, I thought the audio card was bad and replaced it. However, it made no difference. I have no difficulty playing mp3 music files.
I have not seen any error messages regarding flash.

CHOPPY FLASH VIDEO PLAYBACK WITH ADOBE FLASH VERSION 10-11

I'm having a problem as described in a previous post re: Choppy flash videos, pictures, etc.. Youtube, megavideo any videos viewed online appear fine at first and then after 10-15 mins, start showing choppy. The audio was not a problem before, but I have noticed that it is being affected as well. I saw some posts on another forum a few days ago that recommended disabling flash player 11 in my chrome browser plugins and enabling verion 10 (which was available, but has since upgraded) and version 10 was working fine until it upgraded to 11 again. Now I have no options to revert to version 10 again.
My system info is below:
Sony:
OS - Windows 7
64 bit
Browser Chrome 16.0.912.77
Browser FireFox 9.0.1
Browser IE 9
Browser Safari 5.1.2
Flash Player 11,1,102,55
McAfee (came with the upgrade of flash player)
This is very frustrating. I've tried uninstalling and re-installing, rebooting the browser, my pc, deleting cache files and cookies...NOTHING IS WORKING. CPU usage is between 20-35% when a video is active in my browser. I think that is normal, but I know that the choppy playback is not and it's only getting worse. Please HELP!
I hope this NEW POST will suffice as per your requirements.

When the video is choppy, how much CPU and RAM usage is occurring? Do you have a graphics control panel that shows how much video RAM is in use when the video is choppy?
Do you have a list of sites and videos where the video is choppy?
If you don't want the McAffee add-on, remove it.

Youtube video playback freeze

Hi,
I've been experiencing a lot video playback freezing, I've noticed it happens on youtube. It is not my internet connection, the video freeze even it's already been downloaded. It happens with all video resolution from 360P to Full HD, I've tried all majors Internet browser: Firefox, Safari, Chrome.
I have Leopard, a 2.4Ghz Core 2 Duo with 2GB of RAM.
A 250GB HD with (at least) 10GB of free space.
It shouldn't freeze for so low quality videos.
Any help?
Cheers,
-- rafael

Do you have powered speakers or headphones plugged in?
If so, try unplugging them and seeing if it will play the video.
I started having this problem right in the middle of watching a video and it would freeze playback every time I plugged in my speakers. Internet searching yielded no results, but an OS software update from 10.6.2 to 10.6.4 fixed my problem. You say you have Leopard, so I am not sure if a software update is available for you, but check under the apple menu > Software Update. If there is an update related to the operating system, install that. It worked for me!

Choppy youtube video

I have a new 11 inch MBA running Lion. Youtube video unusuable. Choppy, video starts and stops while audio continues. I have the 1.7 GHz Intel Core i5 with 4gig of ram. Can't be the bandwidth of the network, because I can access the same video just fine with my wife's Macbook Pro running Snow Leopard. this laptop is a 2.53 Intel core 2 duo with 8 gigs of ram. The cpu came with Flash version 10,1,52,15 installed. Suggestions? fyi, a 27 inch imac in the same network is accessing the video just fine after running the Lion update.
Keith

Yes, the cpu in quesion is the the mba announced on July 20, 2011. I have run a few more tests and found the video works fine in Safari, the problem is in Firefox. I did install Java the first time I hit a web page that required it. I don't have any other plugins running in Firefox other than
Java 14.0.3
Quicktime 7.7.1
Flash 10.1.52.15
Now that I see using Safari is a fix, this solves my problem. I don't mind switching from Firefox when I require a youtube video. FYI, I saw no problmem on Vimeo.
My experience with setting up and using the MBA has been great. Love the light weight and cool bottom in comparsion to the macbook pro. Thanks for your reply.

Choppy HD Video Playback

Okay I have a 2.6 Ghz Core 2 Duo with 4GB Memory 17" Macbook Pro. I got my MacBook Pro about a month ago and I could watch 1080p trailers perfectly no choppiness or anything. But now I've noticed when I watch them the video gets choppy at points, even videos I've saved and watch in the past perfectly are now getting choppy. What can I do? Should I go to genius bar and see if they can do anything? I have no programs or downloads going on in the background and it still gets choppy, any suggestions would be great, thanks!

I had this exact problem and the cause was Perian.
If you have installed Perian, get rid of it! It's crap and really bogs down video playback.

Hi Def Youtube video playback is sluggish

Hi All
Just bought this Satellite L40D-B laptop with AMD A6 processor and 6G Ram. I updated the AMD video driver but upon playing back Hi Def 1080p or higher Youtube videos, the play back is not smooth but sluggish. Updated the Flash driver, but that did not help.
Please advise solutions. Thanks.
Moby

Open System Preferences > Flash Player then select the Advanced tab.
Click Delete All under Browsing Data and Settings
Not empty the Safari cache.
From your Safari menu bar click Safari > Preferences then select the Advanced tab.
Select: Show Develop menu in menu bar
Now click Develop from the menu bar. From the drop down menu click Empty Caches.
Now try a video.

Choppy YouTube video in ff/vista

By choppy I mean there are small stutters in playback, even when an entire video is downloaded. I've checked connectivity; cache takes care of that issue but I have plenty of available up and down. I checked processing power: plenty of cpu, a new graphics card, lots of memory. I updated to the latest version of flash player. And I can play avi and other videos just fine in winamp, including those at hidef, so it's not a general pc hardware problem.
just in firefox, just in flash videos, from youtube and from other streaming sites.
Suggestions?

Choppy iPhone video playback after upgrading to 10.5 + QuickTime 7.6.9

Hi,
I recently upgraded from 10.4 to 10.5 on my Powerbook G4. I used the "Archive and Install" option. After updating all software to the latest (10.5.8 OSX + 7.6.9 QuickTime), I noticed that the playback of the videos shot with my iPhone 3GS becomes extremely choppy (jumps combined with slow-mo). Based on the what's in "Previous System", I was using QT 7.6.4 with OS 10.4, which didn't have this playback issue.
I found several posts related to similar issues in the forum, and tried the following suggestions without success:
(1) removing all third party plug-ins from /Library/QuickTime;
(2) repair permissions with Disk Utility;
(3) installing Perian;
None of the above made a difference. Just for the heck of it, I tried "su" in Terminal and moved "QuickTimeH264.component" to "QuickTimeH264.component.bkp". Surprisingly this made the playback a lot better (all the iPhone clips are H264+ACC). So I'm guessing somehow the QT H264 component is not working properly for me, but what is QT using instead to play those videos after I renamed the component? It shouldn't be any of the third-party plug-ins since I tried removing all the third-party stuff at the same time, and the videos still played fine. I'd like to get to the bottom of this as I'm a little uneasy about re-naming the H264 component.
I hope someone more QT savvy can diagnose the problem based on what I've tried and make new suggestions. Granted my machine is a bit long in the tooth but it's still decently powered (1.67 GHz, 1.5 GB RAM, 320GB HDD) and the videos played fine before the "upgrade".
Is it worth doing a clean re-install of 10.5 as opposed to the "archive and install"? It's a pain obviously to have to re-install all the apps but I'm willing to try it if it could reasonably make a difference.
Thanks in advance!

The problem is that you moved your Mail application to a sub-folder in your Applications folder, and you are running an older copy of Mail.
From your crash report it shows your path is to a different folder then the default folder:
Path: /Applications/Mail Apps/Mail.app/Contents/MacOS/Mail
It also shows that you are not running the correct version of Mail (should be version 3.5 (930.3):
Version: 3.5 (929.4)
Check out this article:
http://support.apple.com/kb/TS2486
The short of it is that you may have two copies of Mail on your system. When 10.5.6 installed, it may not have updated Mail correctly. Look to see if you have another copy of Mail in your Applications folder, and if so run it and check it's version from the 'About Mail' menu option, it should be 3.5 (930.0). My recommendation is to remove any copy of mail that is not in /Applications (if there is no version of Mail in Applications, move the one you have in Mail Apps back) and run the Mail Update referenced in the article above.

Choppy flv video playback in Safari

Hello,
since a couple of versions now Safari has taken on the bad habit of playing back Flash video in a choppy fashion. No matter what site (Lynda.com, Video2Brain, YouTube etc.), Flash movies just chop, crackle and pop.
Why is that so? No problem in Firefox, Chrome/Chromium.
Thanks for any hints to solve this!

I've restored, but don't see anything else I can try. These problems (or vast majority thereof, e.g. video seeking problems) occur across every iOS device I own or have ever used that runs iOS 8. Are you unable to reproduce them? I'd be very interested to hear if not.
The only thing I've noticed is occasionally is the video screen will not close when pressing Done. I then have to force close Safari. As for poor video quality I haven't experienced that,

I usually edit w FCP7. And My computer never had playback issues w 422 Pro Res files.
CS6 Memory was before on +- 55% and even the single layer video was playing back choppy. So I changed it to 100% not realy knowing what that means. At least the single layer video is playing now fine.

Choppy HD video playback - FCP X

So,
I am trying to work on a music video project, downloaded the trial version of FCP X, and am importing 1080p AVCHD videos (60 fps). When editing the video, any time I playback it runs really choppy. I am running a 15" MBP, from 2009 I believe. It has the 2.66GHz dual core i7, 8GB DDR3 installed, and the 330M (512mb) graphics card. I mean, my computer knowlege tells me that this SHOULDNT be happening. I've run similar setups on older computers without issues with choppy video, so I'm looking for an answer. Also, whenever I just play the videos back (in like VLC or something) they play completely fine. Anyways, please help!!!

Flash Player 10.0.45.2 - Youtube Video playback

Hi guys,
My computer automatically downloaded the new 10.0.45.2 version of Adobe Flash Player sometime last night and now I am unable to play videos on the internet for longer than a couple of seconds - (At most about 90 seconds), I've tried removing flash player with the Adobe uninstall flash tool and then reinstalling it from the link provided on the adobe website but this still hasn't helped at all. I've also tried installing earlier versions of the player, but this hasn't worked either!! My Operating system is Windows XP and my preferred Web Browser is Mozilla Firefox.The problem also persists when I use Internet Explorer and I've noticed that if I stream an audio clip from a website, it will cut off after a period of about 60 - 90 seconds.
How can I make this problem stop??

The same thing happened to me today. Only when I tried to watch a youtube clip it said that my Flash Player was out of date. So...I clicked the link to
update my player and that started a whole bunch of other problems.
I was instructed to uninstall Flash Player Plugin etc. by using the FlashPlayer uninstaller program. I did that and then tried to install the player again. Now I can't because for some reason Internet Explorer keeps closing the tab and won't go back. I have followed links within the Adobe website to resolve this issue but in addition to ie8 closing tabs, I get this message when I click on any link on the website:
ProductMap_kbSmall.processor.importStylesheet:Could not retreive a valid progID of Class: MSXML2.FreeThreadedDOMDocument.3.0. (original exception: undefined)
Has anybody seen this before? I'm sure this is why I am unable to install Flash Player now, but I have no idea how to fix it.
Problem 1: Can't install FlashPlayer
Issue: Internet Explorer 8 keeps closing the tab everytime I click the download button.
Problem 2: The message in bold above. What is it?
Can anybody help me?
Thanks

After the question title has been cleaned up, I can see now that it relates to youtube video playback.
Just embed the youtube html5 video player in a webview and stream video from youtube.
This will work for videos that youtube has made compatible with their html5 player (about 30% it seems).
Here is a sample embedding a youtube hosted trailer uploaded by sony pictures.
import javafx.application.Application;
import javafx.scene.*;
import javafx.scene.web.WebView;
import javafx.stage.Stage;
public class YouTubePlayer extends Application {
public static void main(String[] args) throws Exception { launch(args); }
@Override public void start(final Stage stage) throws Exception {
    final WebView webView = new WebView();
    webView.getEngine().loadContent(
      "<iframe width=\"640\" height=\"390\" src=\"http://www.youtube.com/embed/IyaFEBI_L24\" frameborder=\"0\" allowfullscreen></iframe>"
    stage.setScene(new Scene(webView, 660, 410));
    stage.show();
}If you have any questions, you can read more about youtube embedding here: https://developers.google.com/youtube/player_parameters
