Videos randomly sync and desync

This is not a CPU usage issue I checked. Video will play fine then at random intervals De-sync and stay that way I've done things like clear the cache the everything is fine but after some time has passed lets say 10-20 minutes it then De-syncs. Is there something i can do about this on about:config? Maybe there is something wrong with the cache what are the default settings on each option in about:config relating to this. I have already tried using reset Firefox on trouble shoot still persists. So the options should be set to default maybe a bug, a setting didn't get set right in reset?

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:

  • After upgrading, videos randomly stop and restart.

    Since upgrading to iTunes 10 purchased videos of TV shows randomly stop and restart. I've had these videos for years and never had a problem, but now every time I watch an episode it sill get around 5 minutes in and spontaneously start the episode over. Anyone else having these problems?

    Hi Fabrizio,
    why do you want to reboot your server every sunday?????
    If you reboot your SAP this often, you'll have performance problems every Monday. All
    of your SAP internal Buffers must be filled again after an reboot. If your DB is on the
    same Host, also your DB Buffer is empty.
    If this is an productive System, i highly recommend you that you not reboot your SAP System this often....
    (By side, thats the difference between an *nix and an Windows System.).
    What is the reason for doing that?
    confused

  • When I open Mail the screen flickers random blue and gray appeared on the screen. I took a video too. Will that happen again? Is it hardware problem? This ipad2 32GB was replaced yesterday and I think it is refurbished. Are replace product refurbished?

    I got my ipad2 replaced yesterday. And this new ipad started giving me problem by crashing aps. Then I restored the ipad twice but the problem was still there. I called apple and they fixed it by doing Reset All Settings. But now I have this weird problem. When I open Mail the screen flickers random blue and gray appeared on the screen. I took a video too. Will that happen again? Is it hardware problem? This ipad2 32GB was replaced yesterday and I think it is refurbished. Are replace product refurbished?

    There is no way for anyone here to know if your replacement iPad is a refurbished unit.  Per Apple's replacement policy, replacements can be refurbished units.  If you feel the unit is not working correctly, take it back, let them check it out and if found defective, they will replace that unit.

  • Possible to recover video after stupidly syncing and thus loosing backup file? :'-(

    I have been so stupid.
    My daughter of 3 managed to push 3 buttons on my ipad2 in the exact sequence needed to delete a most wonderfull video. In a panic, I ran to my imac and connected my ipad not realising that by doing so, it was syncing /backing up with itunes.
    In each case, the iOS recovery tool of Dr Fone is not able to see anything except for the videos that are still on the ipad ...
    And on the mac I can only find back one itunes file
    So my questions are:
    1) are these itunes backup files completely overwritten or is a new file made but the old copiy still somewhere on the mac yet made invisible?
    2) does the syncing process overwrite the 'empty space' on my ipad (where the deleted video must be) and is this the reason that the dr Fone software can not retrieve my video?
    3) is there any other tool out there more powerful out there to retrieve deleted files that have been deleted? like some forensics tools?
    Thank you so so much in advance,

  • Camera video preview - Random crashes and green screens

    Hello everyone,
    I am currently working on a Windows Phone 8.1 app and I need to preview video from the phone's back camera. For quite some time I've been struggling with random crashes and green screens. When these green screens appear, all camera apps become affected and
    the device needs to be restarted. Occasionally the phone freezes and only recovers after battery removal. I test the app on my Lumia 620.
    After some web search, I found references to the same problem by many users/developers of different apps. I'm really frustrated as I've tried many possible solutions with no avail.
    Here is part of my code:
    //in App.xaml.cs:
    MediaCaptureInitializationSettings settings;
    public static MediaCapture captureMgr;
    public static bool UnableToInitializeCamera = false;
    public async Task InitializeVideoCapture()
    DeviceInformation backWebcam = await GetCameraDeviceInfoAsync(Windows.Devices.Enumeration.Panel.Back);
    if(captureMgr!=null) captureMgr.Dispose();
    captureMgr = new MediaCapture();
    settings = new MediaCaptureInitializationSettings();
    settings.StreamingCaptureMode = StreamingCaptureMode.Video;
    settings.PhotoCaptureSource = PhotoCaptureSource.VideoPreview;
    settings.AudioDeviceId = "";
    if (backWebcam != null)
    settings.VideoDeviceId = backWebcam.Id;
    else
    var _messageDialog = new MessageDialog("Back panel camera not found");
    _messageDialog.Commands.Add(new UICommand("OK"));
    _messageDialog.ShowAsync();
    try
    await captureMgr.InitializeAsync(settings);
    captureMgr.SetPreviewRotation(VideoRotation.Clockwise90Degrees);
    UnableToInitializeCamera = false;
    catch
    UnableToInitializeCamera = true;
    Debug.WriteLine("HANDLED EXCEPTION: camera could not be initialized");
    var _messageDialog = new MessageDialog("Unable to initialize camera");
    _messageDialog.Commands.Add(new UICommand("OK"));
    _messageDialog.ShowAsync();
    protected override async void OnLaunched(LaunchActivatedEventArgs e)

    private async void OnResuming(object sender, object e)
    AppIsResuming = true;
    FinishedCameraInitialize = false;
    await Task.Delay(TimeSpan.FromSeconds(0.5));//this makes crashes less frequent
    await InitializeVideoCapture();
    FinishedCameraInitialize = true;
    if(WasPreviewingCamera)
    WasPreviewingCamera = false; //the following line allows time for SetupPage._captureElement to be assigned before video preview starts while (!SetupPage.CaptureElementSourceAssigned) await Task.Delay(TimeSpan.FromMilliseconds(1));
    SetupPage.CaptureElementSourceAssigned = false;

    Debug.WriteLine("trying to restart video preview");
    await captureMgr.StartPreviewAsync();

    await CleanupCaptureResources();
    TimeOfLastSuspend = DateTime.Now;
    FinishedCameraInitialize = false;
    GC.Collect();
    deferral.Complete();
    public async Task CleanupCaptureResources()
    if (SetupPage.PreviewingCamera)
    await captureMgr.StopPreviewAsync();
    WasPreviewingCamera = true;
    SetupPage.PreviewingCamera = false;
    else WasPreviewingCamera = false;
    if (captureMgr != null) captureMgr.Dispose();

    void OnSuspending(object sender, Windows.ApplicationModel.SuspendingEventArgs e)
    var deferral = e.SuspendingOperation.GetDeferral();

    Any help towards a solution will be greatly appreciated.
    Thank you

    I will also advice that you start by following the
    Windows Store app sample.
    Is this a Windows Phone app?
    The crash/green screen only manifests itself when I suspend my app and switch to the default camera app (could be any other camera app perhaps). It happens roughly 1 out of 8 times. That's why I posted the suspension and resuming handlers, which I wrote
    according to the msdn instructions.
    I found
    this page with a sample that demonstrates the MediaCapture API for Windows Phone. Some developers have reported problems similar as mine. Has Microsoft dealt with this issue?
    I've spent quite a few weeks trying to investigate this problem, without actually knowing if it is my code that needs to be debugged. That's why I'm asking if other developers are facing similar problems.
    Thank you
    Edit: It seems that the crash/green screen can appear when suspending/switching to any app (regardless if it uses the camera or not). Also, all works fine when the app is running on the debugger.

  • Cannot manually manage music and videos without erasing and syncing first

    I have an iPhone 3G bought new from the Apple store using 2.1. Using iTunes 8.0 and checking the "Manually manage music and video" checkbox, iTunes prompts me to "Erase and Sync", no other option is available to me. It was the same when using version 7.7 as well.
    I'm not syncing to another computer, it's the same MacBook I've had for almost a year. How do I get the Library Persistent ID in iTunes to match the iPhone. I have the ID from the iTunes Music Library.xml file. I just need to know where the matching file for the iPhone is so I can make them match.
    The ID doesn't match because I had to rebuild my drive a month ago and my question to Apple (actually Steve) is why can't I sync the other way from the phone to the computer.
    Why does my library on the phone have to be wiped out. Who had the warped thought to come up with this genius idea.

    I cannot express how disappointing this was for me to find out.
    I want my music to be mobile, I don't want to have to copy it to every computer I want to listen to it on. I want to listen to it from the device, and be able to buy a new album at work or at home. This is a major disappointment for me, as every other device I have owned including my iPod Touch had this capability. I could authorize 5 machines and manually sync, and the music on that device could be played and managed on those authorized machines. For example, my wife has her own music collection, and I have mine, but we have a media center connected to our flat-screen in the living room, that we use for playing music when we are entertaining guests, and with our old iPods and iPod Touch devices, we could unplug one of our devices and plug the other persons in and listen to music from both our libraries without copying the music to that computer, as long as we authorized that machine for the both of us. Now with our iPhones there is no way to keep our seperate librarys and be able to play music on multiple computers in our house and at work, which we have always been able to do until our iPhones. The whole point of the iPhone for me was to be able to combine two devices and now because of the lack of this feature I still have to keep all our iPods around too... Dumb. I almost took our phones back because of this, and if apple doesn't fix it, I probably won't buy another. They should have at least mentioned this little fact before selling the devices to us. I know it's a different device, but it's similar enough that you expect it to work the same as the iPod and iPod Touch. It's not like I am wanting to be able to copy music from the device to multiple machines, it's exactly the opposite... I just want to be able to copy music to the device and listen to it at home and at work... why all apples other devices do this, and the iPhone doesn't is completely perplexing to me, and a serious oversight on there part. This pill would not be so hard to swallow if I had been warned about this prior to dropping almost a grand for iPhones for myself and my wife, expecting what I saw as a more advanced device to work at least as good as the other similar devices I own did.

  • Catalog partially and randomly synced with disc. Have to find and sync A LOT.  Help!  :(

    I am just getting started with LR4.  After installation, the catalog is only partially and randomly synced with my hard drive. (Windows 7)  It seems I have to find and sync way too many files.  There are some files which don't appear in the catalog at all.  So I uninstalled and reinstalled the program and the problem is the same.  Did I miss something or do I have a corrupt program?  Can I find and sync my entire pictures file at once?

    Well, that's a clear indication that the files in question indeed are alreaday somewhere in your catalog; Lightroom is usually right about that. They might not be in the place you expect them to be though.
    You might want to look carefully through the folder structure in Lightroom and see if there are any strange folders you don't remember creating.
    One thing that might have happened during one of the imports is that instead of choosing 'add' in the import window, you had 'copy' selected. When doing that, files end up in the place defined in the right hand column of the import window. Depending on what was selected (or what was there as default), LR has created a folder e.g. with the date of the pictures as name, inside an other folder, etc.
    I encountered this kind of problem myself. An example of what happened:I have my files in folders named by date, in hierarchical year-month-day structure. Using the 'Import' function, I wanted to 'add' the '2011-05-12' to my '2011-05' folder, but erroneously selected 'copy'. Due to the selection I made last time I 'copied' files on import, the folder ended up in the folder '2011-04' - which I didn't notice at first. After the import, I couldn't find the 2011-05-12 folder, and when trying to import the whole 2011 folder with all of its subfolders, it told me that there are no pictures to import as all were already in the catalog. Like in your case, only unchecking 'don't include suspected duplicates' let me see the missing files.
    So try to see if you can find folders where they shouldn't be or folders with unusual names. If that's the case, remove them from the catalog, and your problems will disappear.

  • Videos with syncing, back ups and iCloud

    When you sync or back up does it make a copy or save the video (that you made)?  Does iCloud cover videos you make?

    It saves them in your back up file.
    When you sync or back up
    For the avoidance of doubt syncing and backup are not the same thing, your device will only back up to iCloud when back up is turned on, otherwise it will back up to iTunes when connected to your computer.
    Photostream does not save videos.

  • [Python pygame] Graphic equalizer - keeping sound and video in sync

    Hi!
    I'm writing a graphic equalizer in python and I want to use pygame for the video and audio output.
    The video display of the moving bars works great, now that I have a correct way to read samples and decode them.
    The problem now is: they're way out of sync with the audio playing in the background!
    At the moment my code, that draws the bars basically looks like this:
    # loop as long as we can get slice of the audio file for the fft
    for n_frame in range(0, len(framebuffer), fftframesz):
    clock.tick_busy_loop(t_loop)
    # t_loop was defined as fftframesz over total_frame_count
    # which means in words: t_loop is the amount of FFTs per second - or the cycles of THIS loop
    # grab the frames and perform the fft here
    ...numpy.fft.fft...
    # set the new bar heights and draw them
    for bar in bars:
    bar.update()
    # if playback has not started yet, make it so
    if not pygame.mixer.get_busy():
    musicfile.play()
    The way I'm thinking, this should be enough to keep sound and video in sync. Because we know the time that one cycle should take at most,
    we can set the clock to tick_busy_loop this time. This way we make sure that the video is not faster than the sound.
    But to me it seems that is is the other way round, i.e. that the video is slower than the sound. I already did some timing, but to no avail.
    Is there perhaps a more easy, more elegant way to make sure that image and audio are in sync?
    Any help is greatly appreciated!

    Thanks for your ideas. I assume you mean I should go with a $1200.00 final cut pro software. NOT.
    Sure the video will be on myspace and youtube but wether they are noticed or not is not as important as self satisfaction. I can easily split scenes into equal time zones as I said. Then drag them into clips and back all using the same camcorder. Multiple cameras and angles would be nice but this can be done on a low budget and still look good. I guess my original questions were not answered. Is there a way to determine the length of a transition and shorten the clip by that amount. Or the length of a still shot and do the same. Or perhaps they have been answered and the answer is NO WAY, and I am just not hearing it.
    I suppose reimporting a video would be great if I could use two timelines like in audio and then blank out what I don't want in the first. But I just don't think this is possible, or is it. I've been reading iMovie HD6 The Manual that should have been in the box. It's a help but doesn't take you from the beginning of a project to the final project. Exporting to imovie or idvd is not an issue. BTW I got the clips in sync as I said by leaving blank spots and placing effects over them. I could insert the proper length video in those spots but that can look silly without transitions. But then again so can transitions. This stuff is very fun and interesting and a great learning experience. If I stop now as you suggest then I am not pushing myself to the limit. But thanks for your reply.

  • Audio out of sync and Jumpy video

    I can't seem to get through a project without some sort of critical adobe issue cropping up. Either theres a problem in the editing, or theres a problem in the exporting. Today, its the exporting.
    I just did a large project (6 x 30 minute videos) for a client, and it is a roundtable discussion with slides. Inside premiere, everything plays back fine, but when I exported, the audio got out of sync and you'll see all the slides jump around.

    Anyone have the foggiest idea of whats happening? Its a 2012 rMPB with 8GB RAM and SSD. Exported down to 720p MP4 for review. Nothing else was running on the machine, I just let it render out last night while I was asleep.
    Please help!!

    Last night I exported a queue via AME and sent it to the same USB3 drive that the project was on.
    Today, I exported only one, straight from Premiere onto my Internal SSD and have the same exact issue.
