Choppy streaming video lag

Despite what browser I use, I am getting choppy streaming video - this has never been a problem.
Can not figure it out to save my life right now. I do have the latest software update and flash,
any help?
thanks in advance

  • Choppy streaming video

    Whenever I try to stream online video, such as from youtube, I get extremely choppy video content.  The audio usually works fine, but the video will lag a few seconds each frame and skip quite a bit.  I know that it is not my internet connection, as I have tried streaming the same video's on different computers on the same network (with no problem), as well as tried my macbook on different networks (with the same problem).  I have seen this similar issue in different threads with no clear-cut resolution (and I have tried many of the suggestions from those threads). 
    My issue started about three weeks ago completely randomly.  Since then, I have tried a few things to fix the issue.  I have tried different browsers (firefox, chrome, safari) as well as made sure my adobe flash was updated.  I have updated from Snow Leopard to Lion (was going to anyways, but hoping to fix this issue gave me the final push).  I have repaired my disk through Utilities and also run cleanups through Onyx.  My computer runs completely fine at all other times, but as soon as I try to stream video, the video becomes choppy and my computer becomes as slow as molasses.  Through activity monitor, I have noticed that while streaming (and shortly after) my computer goes to about 0% CPU Idle, with most of the CPU power going something called kernel task, which will run between 100-150 % CPU when the lagginess occurs. 
    Are there any suggestions at all?
    My specs are:
    2.4 GHz Intel Core 2 Duo
    4 GB 1067 MHz DDR3
    Mac OS X 10.7.2

    Through activity monitor, I have noticed that while streaming (and shortly after) my computer goes to about 0% CPU Idle, with most of the CPU power going something called kernel task, which will run between 100-150 % CPU when the lagginess occurs.
    Do you have Activity Monitor set to show"All Processes" instead of  its default of "My Processes?" If not, that leaves the "usual suspects" well under the radar. The "Show"option is in the toolbar of the AM window--this image is from 10.6--might be slightly different in Lion:
    The other items re using AM to find a culprit are:
    1) Use the computer normally for a while before checking AM's status. Items that tend to clog teh system may not show right after a restart.
    2) Close all user applications so the computer is basically "at idle."
    3) Highlight the "%CPU" column to bubble the worst offenders to the top.
    I also like to quit any Dashboard widgets before this test to eliminate clutter; widgets that have to "phone home" can skew the results. To save having to restart the computer to turn off active widgets, get the widget "DashQuit":
    http://www.apple.com/downloads/dashboard/status/dashquit_berenguierduncan.html
    Handy little rascal to have when troubleshooting. Once installed, the Dashquit widget is simply a button that turns off all open widgets.
    If viewing YouTube via Safari, be aware that there are a lot of Safari extensions that might interfere. Try turning off extensions in Safari.
    Let us know what you find.

  • What causes choppy streaming video?

    I have a problem with playing streaming video on my powerbook. The video is choppy but the sound is fine. What exactly causes that? I have a 6 Mbps DSL connection at the house, so I figured it was something internal with the Powerbook. Would this be a graphics card, RAM, or processor issue?? I'm not quite sure. Or is it just a matter of changing a setting?

    Hi BJ,
    Not to state the obvious, but video requires significantly more bandwith than audio.
    What app are you using to stream? What is its internet connection speed set at? What speed does the stream show it's streaming at?

  • EA6500 AC1750 - choppy streaming video

    I have an excellent internet connection - 100Mbps dn and I put a new EA6500 router on it and got all my devices connecting and speedtests showing 40 - 60Mbps on 2.4 band, higher on 5ghz, couple different computers and operating systems throughout my house.
    Invariably on all devices I would get choppy video, cnn, youtube, any streaming video would be start, stop, start, stop at random and for between 1 - 20 seconds and start and stop...
    I switched over to an Asus RT-AC68U and I don't have this problem anymore.  So, now what do I do with my 45 day old Linksys?  I have been watching the forum and it seems unique, obviously I should have figured this out within 30 days and took it back but I figured surely there'll be a simple firmware update or something. 
    Anyone else seeing this?  Can't only be me?

    Does the choppy connection occur on wired or wireless? Or both? Changing wireless channels might help resolved this. You can also adjust the MTU size. Try checking out these links:
    Top causes of dropping wireless connection on a Linksys router
    Resolving dropping wireless connections
    Determining and setting up the correct MTU size
    This router has an Auto update feature. If you have not enabled it, you may download the up to date firmware from this link: http://support.linksys.com/en-us/support/routers/EA6500

  • Is it normal streaming video lagged through AirPlay?

    I just got new iPad and new AppleTV, I played streaming video on my iPad, (which is an app using wi-fi bandwith), I also turn on AirPlay on iPad and mirror to TV through AppleTV2. The router is AirPort, I believe the mirroring also use wi fi bandwith, the result is that the video is lagged so much and can't even watch.
    However, if I use AV cable connect directly from iPad to TV, the streaming video is normal, play perfect, so is it case normal? I don't know if streaming and mirroring use the double bandwith to cause the problem, any advice??
    Thanks
    ziwy

    Mirroring always works fine for me, your network may have a problem such as interference.
    Interference can be caused by other networks in the neighbourhood or from household electrical items.
    You can download and install iStumbler (NetStumbler for windows users) to help you see which channels are used by neighbouring networks so that you can avoid them, but iStumbler will not see household items.
    Refer to your router manual for instructions on changing your wifi channel or adjusting your multicast rate.
    There are other types of problems that can affect networks, but this is by far the most common, hence worth mentioning first.

  • Streaming video lags while Audio continues normally when switching tabs

    It only happens if I go from a streaming video tab to another tab or browser screen/software etc. anything that switches the main view of my screen from the video and back will cause this problem.
    it will play fine at first, but once I look at facebook or bring up itunes etc, and switch back (usually doesnt occur right away, but once the video is a minute or two in it will 100%) the video will start to lag horribly and will never get back on track. the play buttons on youtube/netflix even stay as pause buttons even though I can click play and pause back and forth functionally, and the audio will never skip a beat, but the video will stop dead, lag a few frames and stop dead again and will never correct unless I refresh the page. I can't recreate this in chrome, I've cleared my history and caches, upped the storage size on the main cache and tried updating various things like flash and firefox (19.0) but nothing is solving it!

    You can check for problems caused by recent Flash updates and try these:
    *disable hardware acceleration in the Flash plugin
    *disable protected mode in Flash 11.3 and later (?)

  • IPad streaming video lags when any bluetooth speakers or headset used

    Cannot even watch a Netflix movie or YouTube with any bluetooth device or the streaming video will begin to lag and buffer.  iPad also lags with streaming music, like Pandora.  As soon as I turn off bluetooth, everything works fine.  Why???  I heard it's because bluetooth and Wi-Fi share a antenna which causes a signifcant decrease in performance.  That the same chip is used to decode both signals.  So when both bluetooth and Wi-Fi are being used at the same time the process slows down for both signals.  Is this true???

    I'm in the same boat, I thought it was because I have a ipad 2. It's since the ios 7 update.  Although tonight there was a 7.3 update so you never know they might have fixed it.

  • Choppy streaming video FMS 3.5

    All,
    I'm new to the streaming video world but I do have FMS 3.5 up and running and have encoded some wmv and mp4 videos to flv using adobe encoder CS4.  I followed the tutorials and have created the swf files in flash CS4 and the videos are streaming as expected.
    The primary issue I am having is the videos tend to be choppy at times.  They pause, run slowly, audio pops and just overall; glitchy.  Typically at the beginning but some times throughout.  The test files at the FMS admin page stream fine without issue from the same server.  We have tested the site/streams from multiple providers all at cable modem speed or above.
    We are running FMS 3.5 developer version and wish to purchase the full version but I really need to fix this issue to prove it's value.
    As a bit of background we are running/testing FMS 3.5 from a server with the following specs:
    Redhat EL 4.6-32
    SuperMicro X7DBU Intel Xeon QuadCore DualProc Sata [2Proc]
    Intel Xeon-Harpertown 5420-Quadcore [2.5GHz]
    OEM 4GB ECC FB-DIMM DDR2 
    Mainboard \ Onboard \ SATAII Controller 
    (2) Western Digital WD Caviar RE 16 WD2500YS  
    Uplink speed 10 (Mbps)
    Bandwidth allotment 2000 GB(Virtual Private Rack)
    Any input regarding how to test to identify the issue or past experiences with the same issue will be GREATLY APPRECIATED.  If there are any experienced individuals out there that could get us up to speed quickly we could discuss that offline.
    Thanks!
    Keith

    Hi Jay,
    Answers to your questions:
    1. What bitrate (audio+video) are your files encoded at?
    FLV output file from original wmv: using On2 VP6, 638x480, framerate 29.97, stereo audio 128kbps, video bitrate encoding VBR, encoding pass one, 1,500kbps, undershoot 90, quality: good.
    2. When you experience this choppy playback, how many clients are consuming video from the server at that time?
    1 or 2; we're only testing now and there is almost no load
    3. What is the bufferTime set to in your client side code?
    I'm not sure what this is set to; I know we haven't adjusted it.  Where would I find this code?
    4. Is the server in a datcenter, or is it running on a residential or commercial ISP line?
    server is in the Seattle Softlayer datacenter
    Thanks so much for the help!

  • Choppy streaming video. help

    Hello,
    I have a problem watching streaming video. When ever i try to watch a video online it is very choppy and then when i get to the exact half way point of the movie it just stops. It is very weird and i have no idea what to do.
    Thanks for all the help!

    Are you watching the movie in a web browser (Safari, Firefox, Mozilla) or in a program (Windows Media Player, RealPlayer, Quicktime)?
    Is your software all up-to-date?
    Is your Internet slow in general, or do you only have problems with online videos?

  • Airport express and choppy streaming video

    I am running AX with a DHCP router from my service provider. Up until recently I watched streaming video (Adobe Flash Player) with no problems.  Now the video seems to stutter and have to rebuffer often and it seems to happen when Airport  is "Looking for new Networks".  This means the video stutters every 30 seconds or so.  Is there any way to avoid this?  My connection does not actually drop, it's just the streaming video that gets broken up.
    So far I have tried to
    manually stick to one channel
    reset the airport express to factory settings (which actually helped a bit; stutters from every 10 seconds to every 30 seconds)
    fiddled with interference robustness
    Any suggestions?
    AC

    I'm not sure of the exact length restriction, but I have used a 100' cable with my AirPort Express Base Station (AX) to connect to the stereo and it worked just fine.

  • Streaming Video Lag

    Hi,
    I have iTunes 11 and I'm trying to watch the iTunes Festival. As soon as I Full Screen about a minuite later once the quality improved the video updates 1 frame per second, the lag is unwatchable although the sound stays fine. I tried it on my laptop and different internet connection and the same happens. Any ideas
    Thanks

  • Choppy streaming video from CBS?

    Hello,
    Can someone help me.
    I was watching a CBS stream last night and noticed that the picture was not smooth, but seemed to jump scenes.
    I have Verizon DSL.
    Is this the fault of the IMAC monitor?
    I do not know were to go to test the DSL speed and what speed it should be for smooth video.
    Maybe it is a CBS problem.
    also is eyetv good over slingbox? I have directv and a dvr and just want to use the imac as a tv also.
    Thanks
    Frank

    The problem is most likely with the CBS server being overloaded or under capacity. I have the same problem with them and their news podcasts in iTunes are of very poor quality and available online rather erratically. It looks like Internet video at CBS is still just someone's hobby.

  • Video Lagging/Choppy videos on Macbook Pro

    Hello,
    I am having a problem while watching videos online: video lagging/choppy videos. Sometimes the video is stuck in a certain frame although I still have the sound on the background; sometimes the video slows down completely (frame+sound). It started around one month ago, and exists in several different websites, I couldn`t solve it by myself. I am not very good with computers. I tried to uninstall/reinstall flash player, as well as disable hardware acceleration, and the problem is still there. Also somedays the videos are working fine, and somedays they are all bad independent of websites. I tried to use different browsers (chrome/firefox/safari), but the problem persists.
    I am using a Macbook Pro and bought it in the beginning of January this year (right now it is running OS X 10.7.4) with flash player version 11.2.202.235.
    I would very much appreciate if you can help me.
    Thanks.

    mellskucukoglu, uninstall all adobe products then install Adobe Flash Player, Adobe Reader, Adobe Air, Adobe Shockwave Player. Make sure to select the operating system correctly behind the link. Turn off your antivirus till you finish installation as suggested below the webpage. If it still doesn't work check for OS X 10.7.4 updates.
    If it still doesn't work then go for Adobe Live chat in this link http://www.adobe.com/support/chat/ivrchat.html . Sometimes they are busy. If they can't help. Think about any changes that you made before this issue like installaling any new apps. Uninstall them. If it still doesn't work then install Adobe Flash Professional CS 6. After installing check for adobe updates and update them all. It should work at this point.  If not ,watch this

  • My computer will no longer stream videos? The videos are choppy and show static?

    Hello! My macbook pro just recently stopped streaming videos from facebook, youtube, hulu, etc... The videos are choppy and show static. The sound play back is fine but the picture is definitely unclear. I was hoping that there was a simple solution to this as I have never had an issue with this computer before.
    Thanks,
    Charlotte

    Thanks, Lawrence. I figured that was what I was going to have to do in the end. I have a few games with quite a few hours invested, and I worry that I'll lose the progress I have as they do not save to the cloud. I may have to bite the bullet, and just take the plunge to resolve this. I just want a way to easily transfer my "Home Computer" for my iPhone. My laptop is years old and in need of being replaced, and it's about time to upgrade my phone. These life events piling up are making me consider switching to a friendlier OS. I'm not using this as a threat. I just hope some apple high up will read this, and realize that we need alternatives. Life happens.
    Thank you both Paul and Lawrence. I clicked "This helped me" not knowing it would remove the option to choose "This fixed my problem" too. For anyone else reading this thread. Using the guide provided has done both. It has helped me and given me a fix to my current problem. Lawrence has also provided me with the last bit of information I feel is missing from wjosten's guide. That syncing will completely erase all of your data and reinstall it in one fell swoop. It's a great fix. Even if it isn't the exact one I wanted. Thank you again!

  • All streaming video with my Firefox browser is choppy and constantly stutters and stops and starts. This does not happen with Internet Explorer. Help!!

    Any streaming video that I view on Firefox stutters, is choppy and very irritating to try and watch. I opened up Internet Explorer and found that I don't have those issues. This occurs on YouTube, Facebook, and all other videos that I attempt to watch.

    I've tried both things, but video still stutters.. Have also tried removing profile, and complete reinstall of firefox.
    I'm on 24 Mbit cable and the only user atm. IE and Chrome seems to work without stuttering.
    I've having this stuttering every ~5th second, like a small "1/4 sec buffering".
