Youtube video playback is jumpy.

Youtube was working fine for me a few days ago. Now, when I play videos they are jumpy and shaky. The audio is fine. I have already tried a software update, flash update, and rebooting. What can I do to fix it?

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.

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!

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
FlashUtil9k.exe
FlashUtil10e.exe
install.log
unintall_activeX.exe
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.

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.

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 .

Acrobat X Pro video playback is jumpy

I have created an interactive PDF from InDesign, placing an FLV file which will play back in the PDF. When I preview this on my new iMac 27" it works fine. However when viewing on a Mac Mini (bit old) it is very jumpy if it works at all.
Is this a machine capability thing? If so, does anyone have any idea why doing the same thing with other videos was not an issue? Also why the movie plays fine if opened directly in Adobe Media Player?
Is there anything I can do about it?
Thanks in advance

I'm having the same problem. TV shows played great on itunes 6, but they are unwatchable on itunes 7.
My computer is only an AMD Sempron 2500 with 512mb of Ram. However, x264 plays great full screen.
The problem is itunes and its new DRM.
My solution for now is to stop buying TV shows from itunes until apple fixes this problems.
Since my computer plays x264 video without problems, I'm not going to upgrade my computer to compensate for apple's bad software programming.

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

Sorry, I didn't mean to put this as a reply to your problem. now I don't know how to remove it. Message was edited by: got2monkeys

Play a YouTube video in JavaFX?

Moderator action: deleted rant and cleaned up what remains.
I am trying to make this code play an FLV video, and it doesn't show any video. Only Music. How can I convert, for instance, a YouTube video, to play in JavaFX? If I download a YouTube video, how can i encode it?

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();

Why is the video playback on safari so slow?, why is the video playback on safari so slow?

Recently my Safari is not keeping up with youtube video playback anymore. Firefox on the other hand works just fine. Has anybody else had this problem, or maybe a solution even?

Isolate. New user (follow http://support.apple.com/kb/HT1199). Safe Boot (follow http://support.apple.com/kb/HT1455). Test to see if Quicktime has the same issue by watching videos at http://www.apple.com/findouthow. Is your Flash player up to date? Visit http://www.adobe.com to check. Let us know.

Safari Cannot Load Complete YouTube Videos

Hello everyone,
A couple days back, I've been facing the problem with playing back any YouTube videos properly in Safari. All the videos just stop loading a few seconds before the end, and their playback is therefore interrupted prematurely. Now I'd like to note that I already tried to fix the issue using various methods:
uninstalling the current version of Flash player and installing the latest version provided by Adobe
clearing Safari's cache
disabling hardware acceleration in Flash
disabling HTML5 mode in YouTube
None of these actions had any effect; the problem persists relentlessly.
It's quite frustrating: I'm quite new to OS X, as I bought my iMac only a month ago. Through the whole time, however; I really can't say I would ever notice Safari getting YouTube right. The problems with YouTube video playback have been there all the time; the one described above is the only existing one currently, the others having disappeared with the previous version of YouTube's website.
Any help to be wholeheartedly appreciated.
Thanks in advance,
Mike

Quit Safari ...
Open System Preferences > Flash Player then select the Storage tab. Click: Delete All
Relaunch Safari. Try YouTube.

Youtube fullscreen playback a little jumpy.

Youtube seems to playback a little jumpy when in the fullscreen mode.
I am sure this processor can handle it, how is it for your powerbooks???

Sorry for the double post,
Apple forum's servers seemed to be having problems and kept giving me errors.
I have found a solution to the problem i asked about, it seems that flash does not support hardware scaling of video in fullscreen mode, but a new beta version that adobe has just released includes this.
http://www.adobe.com/shockwave/download/download.cgi?P1ProdVersion=ShockwaveFlash
If u are finding youtube or other flash based video a bit jumpy or having 'splits' across the screen in fullscreen mode, download this beta (at least until they make it an official release).
I guess kick *** new processors relied on power to display the video well.

Jumpy video playback from iPhone 5 to Mac Book Pro

Hi
I recently took some footage on my iPhone 5 and downloaded onto my 2007 Mac Book Pro via iPhoto. Unfortunately, mid download iPhoto became unresponsive and I had to Force quit.
After restarting iPhoto I saw that the videos had not been downloaded so I started the process again. It was a seemingly successful download so I deleted the videos from my iPhone.
Upon playback all the video's are jumpy. Other older video's all ready in the library are fine.
It seems all the info is in there as each time I play a video back I see different parts of the video ie: the jumps are not all in the same place each time.
Is it a playback 780 v 1080 issue?
Can anyone help?
Thanks
Mark

Video playback in YouTube just fine but not Facebook

Video playback in YouTube just fine but in Facebook very choppy. Why? Any fixes?

hi Brandonacker, you probably need to install the adobe flash player plugin for those sites to show video content, which you can download from https://www.adobe.com/products/flashplayer/distribution3.html (use the windows exe-installer for plugin based browsers)

YouTube Videos Stop Playing/Loading During Playback

Can anyone tell me how to fix my iPhone4? When viewing YouTube videos with the App over wifi, everything is good until after a random amount of playback, the download bar stops loading and the video stops playing. This happens on most videos.

I was about to post the same problem - many YouTube videos either won't start downloading to my iPhone 4 or download about 15% then stop. Here's an example of a video that won't start downloading:
http://www.youtube.com/watch?v=EfdK6H9d6J0&feature=youtube_gdata_player
I'm on a very fast cable internet link and ten feet from my Airport Extreme base station. I'm on iOS 4.3.3.
This happens on WiFi or 3G links, everything else works fine.
Recall that the original iPhone ads touted the ability to download and watch YouTube materials. Not so much anymore.

Youtube video playback is jumpy.
