Youtube videos wont play after using Quicktime (which changed my preferenaces) how to fix?

I played a video in Quicktime on my pc (against my better judgement). Quicktime went through my FF & changed everything to be played in QT, now online videos, specificallt Youtube, wont play in my FF browser (3.6.14).
I get sound but no picture.
What do i change back to fix this?I have changed everything to either WMP or VLC to try & get it to play with no luck so i must be missing something?

I had this problem and searched it and came up with a solution that works for me.
First, I only started having this problem for the last few days, this came after a multitude of updates from Adobe and Windows.
The videos would only play (though the sound kept playing) if I kept moving the mouse cursor over the video.
My solution, I went into Tools \ Options \ Advanced \ Network ... and simply cleared the Cache Web Content. I might have also deselected Override Automatic Cache Management ... but regardless, this is the solution that is still working for me.
I should also add that when FireFox gets flaky that's where I always go and that seems to solve any strangeness. Just passing this on.
EDIT ---- Just now I experienced the same thing. I obviously did not fix this issue. Sorry for this unnecessary post.

Youtube video stops playing after 11 seconds

Mac Pro / Mountain Lion 10.8.2 / Flash 11.4 - YouTube videos stop playing after 11 secs. Only just started happening last week - around time when I installed latest Lion upgrade but this may be a red herring. Tried uninstalling Flash and reinstalling with no change. Checked/emptied cache.

There are several topics with similar symptoms, but I don't think anybody has found an answer yet, as it only occurs on some few systems.
What I would try if I encountered the same problem:
try disable Hardware Acceleration (http://forums.adobe.com/thread/891337)
try update the graphics drivers (http://forums.adobe.com/thread/945765)

Why do some YouTube videos stop playing after a short time?

Since sometime in October, 2013, I have noticed that more and more YouTube videos stop playing within a minute of starting. Most that stop do so in 15 or 16 seconds. The playing stops because the download stops. I watch this on a network activity monitor I always have running. Not all videos do this, but the problem is becoming more and more frequent. Some videos which played correctly for me in the recent past are now exhibiting this problem.
Other than installing the latest Firefox updates I have NOT changed the software on my machine. I run Linux by the way. I do not think this is a Linux problem because (1) it was all working before and (2) my son who runs both Mac OS X *and* Windows is also seeing the same problem. We both use Firefox as our browser on all our platforms.
I should also note that I am NOT seeing this problem with any of the other video websites I use, only when I go to YouTube. That leads me to believe that the problem is not in Firefox; if it were it should affect videos from all websites.
Additionally the problem occurs whether or not I log into YouTube.
I have not run Firefox in safe mode because all the extensions I use did not affect the download of Videos before, so I don't expect unchanged extensions to suddenly start causing problems.
So, anyone else see this problem? (There was another note which talked about the same problem but it was disabled.)
Also -- pardon my paranoia, but -- I need to ask: Since YouTube is owned by Google and Google has its own browser it wants you to use, Chrome, is it possible that Google is intentionally causing some YouTube videos to fail if it sees that they are being sent to Firefox?
(That is not so outlandish I think. Microsoft WAS at one point caught mangling web pages going to certain web browsers other than IE. And these days Google wants to dominate the Internet just as badly as Microsoft does, so why not pull dirty tricks too?)
If this keeps happening I am going to have to try Google's Chrome to see if it somehow manages to play YouTube videos correctly while Firefox does not. But I really do NOT want to install Chrome because I trust Google about as much as I trust Microsoft, which is to say Not At All.
Thanks in advance.

Hello,
There have been some issues with Flash 11 in the recent past. This could be a manifestation of that issue. Kindly check this response below to see if this helps you in viewing Flash videos.
Also, if you want to check if this is a flash problem and specifically on youtube, you can try the HTML5 version of Youtube. In this, there are no plugins involved, and the browser natively renders the videos. You can signup for the HTML5 trial by visiting http://youtube.com/html5. Please try that and check if the issue goes away.
Also, in this case, Google might not be doing anything sinister - they generally try to be standards compliant too. You can definitely try installing Google Chrome and test this issue, but we definitely would want you to continue to be a Firefox user :)
<hr>
Some problems with Flash video playback can be resolved by disabling hardware acceleration in your Flash Player settings. (See [[Flash Plugin - Keep it up to date and troubleshoot problems|this article]] for more information on using the Flash plugin in Firefox).
To disable hardware acceleration in Flash Player:
#Go to this [http://helpx.adobe.com/flash-player/kb/video-playback-issues.html#main_Solve_video_playback_issues Adobe Flash Player Help page].
#Right-click on the Flash Player logo on that page.
#Click on '''Settings''' in the context menu. The Adobe Flash Player Settings screen will open.
# Click on the icon at the bottom-left of the Adobe Flash Player Settings window to open the Display panel. <br/> <br/>[[Image:fpSettings1.PNG]] <br/>
# Remove the check mark from '''Enable hardware acceleration'''.
# Click '''Close''' to close the Adobe Flash Player Settings Window.
# Restart Firefox.
This [http://www.macromedia.com/support/documentation/en/flashplayer/help/help01.html Flash Player Help - Display Settings page] has more information on Flash Player hardware acceleration, if you're interested.
<hr>
Also, try this one too
Recent crashes of certain multimedia contents (this includes Youtube videos, certain flash games and other applications) in conjunction with Firefox are most probably caused by a recent Flash update and/or a malfunctioning browser plugin such as Real Player.
In order to remedy the problem, please perform the steps mentioned in these Knowledge Base articles:
* [[Flash Plugin - Keep it up to date and troubleshoot problems]]
* [[Flash 11.3 crashes]]
* [[Flash 11.3 doesn't load video in Firefox]]

How to stop youtube videos from playing after restart

every time I restart firefox (currently 24.1.1 or 14.0.1) any tabs with youtube videos start playing and I have to wait until after restart is complete before I can find it/them.
is there a way to stop this?

I don't know of a way to stop auto-play on restart only. There are some extensions that can stop auto-play in general (i.e., all the time). I haven't tried any of them myself, but it looks as though these might help:
* [https://addons.mozilla.org/En-us/firefox/addon/smartvideo-for-youtube-mytube/ SmartVideo For YouTube]
* [https://addons.mozilla.org/En-us/firefox/addon/stop-youtube-autoplay/ Stop YouTube Autoplay] (updated version not yet reviewed)

The video player mentioned in your opening remark is for a QT player, not a Flash, so for that you would not be using those Flash .swf files.
<OBJECT CLASSID="clsid:02BF25D5-8C17-4B23-BC80-D3488ABDDC6B"
Farther down I see a banner .swf, but that's NOT the video in question is it?
Also, you are using 2 different paths, one in the <object>:
<PARAM NAME="src" VALUE="../Video/../Video/Mitel_Unified_Communicator_Advanced.mp4" >
and a different path in the <embed>
<EMBED SRC="../Video/Mitel_Unified_Communicator_Advanced.mp4
You didn't mention what browser/s you have tested in and you didn't mention if you are testing the videos directly (click on mp4 file and open directly in QT) or if you tested in a browser locally before uploading to server.
Does the Browser you are testing in have a QuickTime pluggin? if not, the video will not display
Quite a number of variables.. for more help, please post a link to the actual page.

Lollipop Update 5.0.1 Yoga Tablet 2 10 YouTube videos wont play on Facebook

since lollipop update yoga tab 2 ten inch. no youtube videos work on facebook on broswer mode. i dont use the spyware app just the broswer version.
Admin edit; subject edited to be more descriptive

I found an article which suggests the following workaround:
"This has worked for some people so it’s worth a try. Go to Settings > About tablet or About phone and tap the Build number seven times. This will unlock Developer options in Settings. Scroll down until you see an entry under Media that says Use NuPlayer (experimental) and try disabling it. Now restart your device.

Please let me know if this resolves the issue.

hello,

I tried the following :
1. Clear the cache and cookies only from websites that cause problems. - Didnt work

Try disabling graphics hardware acceleration. You might need to restart Firefox in order for this to take effect, so save all work first (e.g., mail you are composing, online documents you're editing, etc.).
Then perform these steps:
*Click the orange Firefox button at the top left, then select the "Options" button, or, if there is no Firefox button at the top, go to Tools > Options.
*In the Firefox options window click the ''Advanced'' tab, then select "General".
*In the settings list, you should find the ''Use hardware acceleration when available'' checkbox. Uncheck this checkbox.
*Now, restart Firefox and see if the problems persist.
Additionally, please check for updates for your graphics driver by following the steps mentioned in the following Knowledge base articles:
* [[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]]
* [[Upgrade your graphics drivers to use hardware acceleration and WebGL]]

When I play a youtube video in one tab, then scroll up and down in any tab, the audio from the youtube video gets choppy and cuts out for a second. How to fix?

I just want to be able to go on other websites and scroll while playing music (smoothly) on youtube in another tab.
I don't think this happened until after I updated my firefox to 13 and my shockwave flash plug-in to 11.3.300.257
How can I fix this cutting out and choppy-ness in youtube videos when I scroll?
Thanks so much!

Try to disable hardware acceleration.

TA21328 youtube videos stop playing after few seconds

While watching videos on youtube, sometimes the videos are stopping or freezing after few seconds of play. How can I fix this?

If you have a slower connection and try to watch hd then your computer won't be able to keep up. Could that be the problem? If it is, just click on the quality wheel, and watch at a lower quality, say 480.

Youtube videos wont play

hi!
i have the new ipod touch 16 giga and whenever i try to watch any video on youtube it sais:
"this video could not be played"
any suggestions ?

This isn't a typical problem for Touch, but others have had the same problem. YouTube offers support here:

Uninstalling and reinstalling Flash seems to work on several platforms.

Videos wont play after publishing

I have imported several .flv videos into my project, and they all play well when I do a preview, but once I publish the project the videos just come up as a blank frame. The video files seemed to be automatically placed in the same folder as the swf, so I don't think that is the issue.
Does anyone know why this might be happening?

Hi Drakier,
Try a small test. Create a new project with the same dimensions of your existing project. Copy and paste 2-3 slides from your project that contains the flv videos and then publish the project.
Observe that now are you able to play the project perfectly fine or not.
Also if it does not play in the test project then add the test swf in the Flash Trusted Location. After adding the test swf in the trusted location if it plays fine then try to add your existing swf in the trusted location as well.
Hope it helps
Thanks

Videos wont play after syncing on ipad

i have a tv show that i converted from an avi file to a mp4 file. I imported it into itunes, and then did a sync with my ipad 2. when i select video on the ipad all i get is a black screen. there is another movie that i synced as well that was working yesterday now none of it works. any ideas what i might be doing wrong?

My guess is that the format is not fully compatible with the iPad. I would delete it from the iPad. I would first try using the Create iPad and Apple TV Version in the Advanced tab of iTunes.
How (what program) did you convert the video and what were the specifics of the format you converted to?

My video wont play after frame 1 but plays sound! can anyone help?

it's only one video that I have imported - all the others work fine..?

If you move the volume up and down button, does it show that it's in headphone mode?

Youtube videos wont play after using Quicktime (which changed my preferenaces) how to fix?
