YouTube and videos slow on Firefox

Hi, I have tried to resolve this on my own, but i couldn't so please, help me.
I'm having BIG troubles trying to reproduce any video in YouTube. When i try to watch something, the video goes terribly slow, with continuos jumps and hangs, however the audio still is being reproduce perfectly.
I have the last Adobe Flash Player version installed, if i go here http://helpx.adobe.com/flash-player.html it says it. But the animation i should see in that page to check if everything is ok, is really slow, and it has those jumps, the same than youtube.
I have tried to unistall, and install it again, but it doesn't work.
My computer is: Windows 7 64 bits, AMD FX 6300 6 core, GTX 650, 8 Gb RAM, motherboard ASRock 980DE3/U3S3 i'm using Firefox 35. and last version of flash player.
By the way, if i tri to use Chrome, it works I believe it's because Chrome has it installed by default, so the problem it's just with Firefox (or games than nead Flash player installed)

It sounds like you have an excellent workaround available.
You can try to resolve the issues in Firefox by taking a look at our video troubleshooting guide:
Video playback issues
If that doesn't work, your best short-term option is probably to use Chrome.

So, the upload time will vary on internet connection. If there is an issue with how fast it is uploaded you can check if prefetching is turned on, but this does not really affect uploading [https://developer.mozilla.org/en-US/docs/Controlling_DNS_prefetching Controlling DNS prefetching]
If you search for solutions, you will see a bunch of tweaks as well that may be helpful to your specific computer. [[Upgrade your graphics drivers to use hardware acceleration and WebGL]] to make sure you are all up to date as well.

Youtube and videos keep downloading so that the lecture stops and goes on by "increments"each 2 seconds

Youtube and videos are not running fluently the way they did. It goes on downloading each 2 seconds. What can I do to solve the issue ? Thank you for your help.

Most YouTube content requires the Flash plugin. Sometimes it's necessary to uninstall then reinstall that plugin.
Uninstall the Flash plugin then reinstall new > Troubleshoot Flash Player | Mac OS
Very important to uninstall the currently installed plugin first.
Now launch Safari and try a video.
If you have the ClickToFlash extension installed, that can prevent Flash based video from streaming. It can also be installed as a plugin in /Library/Internet-Plug-Ins.
And check to see if Safari is running in 32 bit mode. Right or control click the Safari icon in your Applications folder then click Get Info. If the box next to: Open in 32 bit mode is selected, deselect, quit then relaunch Safari.
You may also need to delete the cache associated with Safari .
Open the Finder. From the Finder menu bar click Go > Go to Folder
Type or copy/paste: ~/Library/Caches/com.apple.Safari
Click Go the move the Cache.db file from the com.apple.Safari folder to the Trash.
Quit and relaunch Safari. Try a video.

Youtube and videos

i have recently been unable to view videos (youtube and other site) on safari! the site loads up but the video does not show up or play!
how do i resolve this?

First thing is to always try a reset, then a restore.
Remember that sometimes YouTube "goes down", and sometimes (if viewing over Edge) you will have such poor reception that videos will not play (other things can still load but video needs a better bandwidth in order to play). However, if you are connecting via wi-fi and they do not play the reset/restore is always the first thing to try.

[SOLVED] sound and video issues with firefox

I decided to change my browser due to some problems with the last chromium update (https://bbs.archlinux.org/viewtopic.php?id=182218).
I'm using the last version of firefox but I can't watch any videos in this browser. I'm having two main problems:
· There is no sound at all in the videos played. But there is sound if I play something with Clementine or mplayer
· The videos stop after a few seconds automatically. The videos keep loading, but they are not played anymore.
This is a weird thing. I can't use a browser! Please some help!
PS: I change the player on youtube to HTML5 and it's working now

Hello,
While the whiteboard itself doesn't have an upload command,
the FilePublisher can upload images into the Cocomo room. From
there, your clients can download the image and display it (say,
through an image component). The SharedWhiteboard can have its
backgroundAlpha set to 0 - try myWB.setStyle("backgroundAlpha", 0).
As far as your audio is concerned, it seems as though you're
compiling against the FP10 cocomo.swc, but aren't requiring player
10 in your Flex project (check Project Properties->Flex
Compiler). I'd either use the FP9 swc, or require 10.0.0 or higher
in the project.
hope that helps

[SOLVED]Youtube and Video Codecs

Hey guys
Ok basically today i went to make a screen recording for a friend. and i got this command line of the internet, youtube itself actually. i do remember the guy on the video saying he converts it later
The recording went fine. better than fine, x11grab is impressive
But when i uploaded the video to youtube, youtube failed to process the video, saying it couldnt read the codec
ffmpeg -f alsa -ac 2 -i pulse -f x11grab -r 30 -s $(xwininfo -root | grep 'geometry' | awk '{print$2;}') -i :0.0 -acodec pcm_s16le -vcodec libx264 -vpre lossless_ultrafast -threads 0 -y output.avi
So im wondering how i'd go about converting the file into a format that youtube will accept
i did try this, it convers the video itself but with no audio
mencoder output.avi -o test.mp4 -oac copy -ovc lavc -lavcopts vcodec=mpeg1video -of mpeg
due to this error
mencoder unknown audio format assuming mp2/3 use -fafmttag
I did try searching the arch forums and google. i couldnt find a solution or whats happening with the audio situation with mencoder

If you want to tweak a few parameters along the way:
ffmpeg -i 'input-file.avi' -r 25 -s 640x368 -aspect 16:9 -b 988k -vcodec libxvid -vtag xvid -metadata title='Metainfo Title' -acodec libmp3lame -ac 2 -ab 128k 'output-file.avi'
or to purely copy video as is and transcode audio:
ffmpeg -i 'input.avi' -sameq -vcodec mpeg4 -acodec libmp3lame -ac 2 -ab 128k 'output-file.avi'
man ffmpeg
for more info and other options

IWeb questions - Youtube and Videos.

Hi,
A few quick questions
1) How do you put a link into a page so that visitors see the movie (let's say it's on Youtube) but are not directed to the actual page. Here is a link to a website that accesses one of my Youtube videos, yet it doesn't bring the visitor to Youtube.com. http://starsneverfade.com/callowayConcert.htm Here is another example of how someone access a video on my website without visiting my site. Both of these have my permission... but how was it done? http://www.davidgeist.com/rhapsodyinblue.html
2) is it possible to put a Flash movie into Iweb? I have a few people grumbling that they cannot play Quicktime movies. I hear .flv movies are more compatible with Windows based computer... augh! Why doesn't everyone just buy a Mac and make my life easier?
3) Is it possible to copy protect a video? What I'm asking is once I post a video is there a way to prevent people from downloading it?
Thanks!
Gary

I have a large collection of sample pages with video: QuickTime, Flash Video, Windows Media, DivX, Real.
http://web.mac.com/wyodor/iFrame/
You use the object/embed code and paste it in a HTML Snippet.
I usually use a separate custom HTML page to embed with the [iframe HTML element|http://htmlhelp.com/reference/html40/special/iframe.html] or [object HTML element|http://htmlhelp.com/reference/html40/special/object.html].
I have a few people grumbling that they cannot play Quicktime movies. I hear .flv movies are more compatible with Windows based computer... augh! Why doesn't everyone just buy a Mac and make my life easier?
It's not Win or Mac. It's what you want. Flash Video has advantages over QT. And DivX has advantages over Flash Video. And Vimeo has advantages over YouTube. The samples will show you.
3) Is it possible to copy protect a video? What I'm asking is once I post a video is there a way to prevent people from downloading it?
If I can watch it, I can download it.

Hello ssk2301, sometimes a problem with Firefox may be a result of malware installed on your computer, that you may not be aware of.

Why is Firefox 4 and 5 slower than firefox 3 in Mac OS X Snow Leopard?

You told me Firefox 4 was fast, so I upgraded from the latest release of 3.xx. Immediately I started seeing a pinwheel mouse cursor when I had more than about 5 or 6 tabs showing (the pinwheel is the Mac OS X equivalent of the Windows hourglass, at least in Snow Leopard). I have the latest release of Firefox 5 and I'm still seeing pinwheels.
This happens several times a day, but not every time Firefox opens. It usually takes a few minutes for the pinwheel to show up. When it gets to where the pinwheel appears to be permanent, I Force Quit Firefox and restart it, and that helps for a while.

Did you want me to re-post this in that forum or can one of the mods from here move it?

Ping and download slow in Firefox/ not IE or Chrome

I've reinstalled, created new profile, tried safe mode, ran virus checks and malware checks, disabled Protected Mode in Flash. The first try after shutting off ProtedtedMode gave good results. But now it's back to twice the numbers I get from Chrome and IE. DSL provider had me ping from the command prompt, and all is OK. What else can I try, so I can stay with Firefox?

Which tests are you running (i.e., URL please)?
I assume these are pure Flash tests; do you have any comparison data from Flash 11.3 to know whether it's something new in Flash 11.4?
In Safe Mode, Firefox's native hardware graphics acceleration feature is disabled, but you also could disable it in normal mode as there occasionally are conflicts with display drivers which create performance problems.
You usually 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.).
orange Firefox button ''or'' classic Tools menu > Options > Advanced
On the "General" mini-tab, uncheck the box for "Use hardware acceleration when available"

I use Adobe Flash player version 11.7.700.225 why do my YouTube and other videos keep stopping

I use Adobe Flash player version 11.7.700.225 which is the latest version. can anybody tell me why my YouTube and videos stop and I cannot view them I have a macbook pro with retina display late 2012 and I am running OSX 10.8.4. Do I need some other flash to view or what thanks for your time.

noelenefromashford,
I'm in the same boat. Safari 6.0.5, stalls, and stops playing video (youtube, vimeo, etc). I tried the same videos with Firefox and they play fine!
Running 10.8.4 on Mac tower.
I just switched from an older Macbook Pro 15" with the same OS version and browsers , and never had that issue. What gives?

Audio/Video Slow Down

I've been using Windows 7 since August and installed an X-Fi Titanium about two months ago with no incidents. ?For unrelated reasons, I had to reformat about a week ago. ?This leads to my current problem:
Whenever I playback a video source, be it streaming, on my hdd, or dvd, my audio and video slow way down, about 0% of the normal speed. ?The video slow down only affects these sources, games and windows explorer work normally at full speed, but the audio is still at the same slow speed. ?Only a full system restart seems to fix it. ?
Strangely, this problem doesn't seem to affect .divx files (note .divx, avi's encoded with divx still causes the slowdowns).
I've installed the newest video and audio drivers; updated my codecs; tried multiple browsers and media players; rolled back to older drivers; tried the various modded drivers on the forum; tried streaming media on a VM, slowdown still happens; restarting device via device management; used windows 7 auto update drivers; scanned for spyware/virus; another reformat; removed stick of ram (brought down to 2gb from 4); ran chkdsk; and in total, spent about 0 hours googling possible fixes.
My system specs are as follows:
Windows 7 Pro x64
AMD Phenom 9600 2.3 GHz
Sapphire 4870 gb
4gb DDR2 Ram
Asus M3A32-MVP Deluxe Mobo
2x 32gb patriot ssd (System Dri've)
320gb WD Hdd?
Logitech 5. speakers Connected via analogue
PS3 connected to Optical In
If anyone could shed some light on this, it would be greatly appreciated. ?I'm just about at my wit's end here and I currently don't have the funds to buy anything different for my system. ?Thanks for taking the time to read this.

you want a video to play at something other than its native framerate?
if yes, you can't easily do that with an flvplayback component. you'll need to separate the audio and visual parts of your video and had them to a movieclip timeline. then you'll need to customize the playback speed of that movieclip.
you can use the following to play any movieclip (forward or backward) at any speed:
function playF(mc:MovieClip, m:int, n:int, fps:int):void {
    var playFFF2:Function = function(mc:MovieClip):void {
        trace(getTimer(),mc.currentFrame);
        if (mc.m<mc.n) {
            mc.nextFrame();
        } else {
            mc.prevFrame();
        if (mc.currentFrame == mc.n) {
            clearInterval(mc.int);
        //updateAfterEvent();
    mc.m = m;
    mc.n = n;
    mc.fps = fps;
    mc.gotoAndStop(mc.m);
    clearInterval(mc.int);
    mc.int = setInterval(playFFF2, 1000/mc.fps, mc);
// and to stop it:
function stopF(mc:MovieClip):void {
    clearInterval(mc.int);

Choppy/Slow streamed videos on both Firefox and Chrome

I have a 2010 Macbook Pro that was recently turned off for two weeks while I was on vacation. When I turned it back on and tried to watch videos online (youtube, Netflix, streamed videos) the videos are choppy and slow to load. This was never a problem before turning of the computer for the two weeks. I have tried both Google Chrome and Firefox and the problem happens on both. When viewing the Activity Monitor while attempting to watch the videos the CPU usage is fine for the first 20 seconds or so and then Chrome or Firefox take on 80-90-over 100% of the CPU usage, a majority of the usage is from the system (in red) and the videos become untwatchable. I have uninstalled and reinstalled both browsers and have disbaled all the extensions. I have uninstalled and reinstalled Silverlight for Netflix and have uninstalled all unused versions of Adobe Flash player. There are no problems with video when I watch a DVD. Help! I want to watch videos again

having same problem since mac os x 10.6 upgrade, but was never issue prior... have tried everything i can think of, new flash players, reinstalling players, reboots of computer and router... to no avail. since this was never an issue for me prior to upgrading to Mac OS X (10.6.8), i believe its the os software.

Several problems continuous since first installing Firefox. Personal google search settings don't save; remember me options on web sites like Facebook aren't remembered; Youtube and Flixy videos don't play despite removing/reinstalling/upgrading Firefox s

Several problems continuous since first installing Firefox. Personal google search settings don't save; remember me options on web sites like Facebook aren't remembered; Youtube and Flixy videos don't play despite removing/reinstalling/upgrading Firefox several times; upgraded the latest flash plugin today, but no difference, symptoms are black play box with youtube and white box with Flixy. Disbale AV and antimalware makes no difference either.

Videos won't stream (eg youtube) and safari very slow

Hi, I have 2 problems and would really appreciate any help
1 - safari very slow to open pages and has been like this for weeks. I have seen a solution to change to 'opendns' under System preferences > network > advanced tab but I cannot see an option for that. I think this may be my problem as Google always opens quickly. Can anyone elaborate on this solution?
2 - Videos won't stream and just hang with circle (e.g on sites like youtube) which started about 1 week ago. Only thing I have done differently is watching megavideos on unknown site. I have tried the solutions given under other threads (e.g. deleting cache files and uninstalling and reinstalling adobe flash). This seemed to help slightly the first time I tried it but still took approx 60s to stream 1 minute video. Has now reverted back to not streaming.

To set up a test account, open System Preferences > Accounts, click on the padlock icon to unlock it, then click on the "+" sign, name the account "test" and leave the password field blank, since you don't need the account that long; you can delete it later.
Quit System Preferences, log out of the regular user account and into the test account, then try using Safari to load pages and videos to see if the problem continues there.
Other things you can try in your regular user account that may help your problem or solve it are this:
1. Go to Home/Library/Caches/com.apple.Safari and delete the contents of that folder.
2. Go to Home/Library/Caches/com.apple.Safari/Web Page Previews and delete the contents of that folder.
3. If you don't want to use the Top Sites or Cover Flow features, open Terminal and paste in this command:
defaults write com.apple.Safari DebugSnapshotsUpdatePolicy -int 2
then press Enter or Return and quit Terminal
4. Go to Home/Library/Caches/Metadata/Safari and delete the contents of that folder.
5. Go to Home/Library/Caches/Safari and delete the contents of that folder.
6. Go to Home/Library/Safari and delete these files (if you have them):
Downloads.plist
History.plist
Form Values
LastSession.plist
WebpageIcons.db
Then Repair Permissions, restart Safari and see if the speed is improved.
