Problems mirroring the iMac on television during video playback using VLC Player

At the end of 2015, I bought a 4th generation (32 GB) Apple TV and an iMac with OS X El Capitan 10.11.6

When I try to reflect my screen FRO my iMac to the TV using Apple TV video (playing through VLC) is nervous and rambling. I talked to Apple Support and they conclude that video game through VLC was the problem and VLC should perform updates to the new Apple TV. I was told that Quicktime was the only guarantee program to watch the video through, but a lot of file formats I have are not compatible with Quicktime. I know that Quicktime converts the files now, but sometimes they take forever and some files won't convert. Apple Support guy told me to another way to convert the files, but I don't remember what he says now! I did the latest VLC and am finding it's really frustrating because it was the reason why I bought the Apple TV in the first place. Any suggestions on a faster way to work around this problem? Thank you!

When air time and performance is compromised it is usually an interference of the network rather than a software problem, a

  • Keeping the backlight on during video playback with alarm does not not with OS 4.7 round

    I am developing an app that plays the video using the alarm, like this:

    player_ = Manager.createPlayer(url);
    VideoControl_ = (VideoControl) player_.getControl("VideoControl");
                    videoControl_.initDisplayMode(VideoControl.USE_GUI_PRIMITIVE,                 "net.rim.device.api.ui.Field");

    The duration of the video is longer than 2 minutes. On OS 4.6 device such as the curve, the video plays without the screen goes black.

    However, on the circuit of 4.7 OS, screen goes black even if I try to activate the backlight on regularly, like this:

  • Media Center crashes during video playback of need to hard reboot.

    Hi, any help would be greatly appreciated as this has been driving me crazy for several days of attempted troubleshooting, Googling, try many things to fix it... first of all let me apologize in advance for the length of my post but I wanted to give as much information as possible to help anyone trying to rule out things...!

    OK, so the problem...

    I installed Windows 7 Ultimate 32 bit as a clean install on my HTPC, after the first do a complete 1 & 0 format of the hard drive that had previously installed Vista Home Premium, installation went well and I proceeded to install all updates to Windows, and then update drivers for all my hardware.

    The system is used only as a HTPC, it's my only TV and video playback device, (so reliability is essential for me) and it is connected to a defintion of Sony, 44 "Widescreen Rear Projection TV Standard, via S-video, with audio goes to a system DD/DTS 5.1 Surround Sound Speaker Logitech z5500, via a sound card by using the optical cable (specifications of the complete system below).  The system worked flawlessly more of one year using Vista SP1 32 - bit, until I upgraded to Windows 7 Ultimate on the hardware configuration identical.

    Since installing Windows 7, it worked fine for the first week, not a single problem, I am housebound are disabled so that the system is in continuous service 24/7 and he had no problems in the first 10 days, however all of a sudden I'm getting now random freezes requiring a hard reset , but it occurs during video playback of any of my 3 hard disks, or when you try to play a DVD in Media Center. Which led me to think it is associated video (problem of driver or hardware fault) card, disc or HARD associated.

    Frost can occur sometimes, after a few minutes of reading, or sometimes after a few hours, requiring a restart of the hard to get the sytem to answer.

    Reading of the TV via the TV Tuner card is not affected, its only when playing of stored content (MPEG2, h264 .mkv .avi files or DVD) are all media SD HD and all played fine for the first few days.

    Intermittent freezes occurring could block the system completely freeze the image and audio and all activities, nothing would work at all, I tried windwos keyboard, ctrl alt del, nothing at all, to do a reboot hard to recover the system, it can then be either minutes or sometimes an hour before the same thing happens again. I tried to use different video files in the case of the corruption of files, different DVD to exclude damaged disks, same result.

    System includes:

    All of the above software has been installed by using the latest available versions downloaded from the manufactuer sites, which claim to support Windows 7 and all have been updated regularly since its installation.

    I have tried many of the suggestions I've seen posted to try to solve this problem, including:

    1. Uninstalling and reinstalling Media Center and WMP
    2. Disabling subtitles in Media Center
    3. Disable unused mobo onboard devices in the BIOS
    4. Update BIOS
    5. Updated all drivers

    12. Tried playing files AVI of HDD separated to avoid a HARD drive problem - same problem occurs on all readers
    13. I tried change graphics card for an ATI HD4850 with the latest ATI drivers - same problem.
    14. Tried to change the audio output S/PDIF instead of Xonar Soundcard onboard - same problem occurs
    15. Tried the Windows 7 repair facility - problem persists.
    16. Tried to uninstall all updates of Windows -same problem
    17. I tried the system restore to before the occurrence of the problem started - no help
    18. tried to re-downlaoding all hardware drivers updated and re - install in the case of a corrupt driver download - no chance even problem

    Essentially none of the abvoe helped to solve this problem, and it becomes really frustrating to have to restart the PC again and again trying to watch a recorded video file or DVD.

    After remove all the above I can only assume that it is a problem with Windows 7, needing a fix of the millisecond.  At least I think that I've exhausted everything I can try... ???

    With what is my HTPC, if I can't perform reliably, I have to reinstall Vista, Vista was not the best OS, but at least it was reliable for me in terms of my HTPC.

    I was really eager to get Windows 7, I used the RTM version on my netbook for some time before I made the decision to purchase the full retail version for my HTPC, and never had any of these problems with my installation of netbook that I used for playback of media files from an external USB HDD.  So I'm really disappointed to have these problems after doing all that I could to make sure that Windows 7 would work OK.

    If anyone can give me any suggestions of what I can try, anythign I can too watching, or if someone has hada similar problem and found a solution for him... Please, please, post more details, because I am really at my wits end now and have to resort to watch the recordings on a 10.2 "screen of my netbook with some speakers of the small laptop usb, after spending so much money on my system and surround sound Setup HTPC, its devastating to think that I'll have to go back to Vista...

    Absoultely ANY suggestions would be appreciated...

    Thanks in advance for any help and once again, I'm sorry for the length of the post, if there is more information needed I've not provided above, please let me know and I will try to publish as soon as POSSIBLE...

    After the forum of scouring and reding of countless discussions, it seems, there is some sort of problem with Media Network Sharing tha could be the cause of this problem, as many people have reported that disabling wmpnetwk.exe in the Services.msc solves the problem.

    It's not an ideal solution for me, as I have a HTPC in the room that I play media from the main HTPC downstairs and all the hype MS seemed to suggest that Win 7 is it is much easier to achieve, and has been one of the main points of sale used in one of their commercials for the operating system.

    This my MS you need to pay attention to this problem and work towards a solution and allow users to know when the solution has been provided, probably have a service that must be disabled to let the operating system work reliably is quite counterproductive.

    Nobody seems to answer my post above with other suggestions and wmpnetwork.exe disable workaround was published last November, all the while still there is no permanent solution...?

    EDIT: Just to confirm this wmnetwork.exe Netwrok disabling media sharing in the services, as well as disabling the media streaming in the Netwrok Sharing Center > advanced sharing Options, solved the constant crashes for me.

    So all the MS speak of 3rd party drivers for the cards video and other material or material defects are to blame, it's total BS, the only problem is to do with Windows and Windows Media Sharing, lets hope, they decide to do something to fight it... !!

  • I have a thumping sound during video playback.

    I have a computer Dell Inspiron 1545, 64-bit laptop, equipped with Windows 7 family Premium SP1. During video playback, streaming online or a video on my computer, I get a noise very loud from time to time. It is almost an audio feedback effect. Sometimes the video hangs at the noise. I've updated the audio drivers; I deleted the audio driver in the Device Manager and rebooted I tried another card sound and different speakers. Nothing works; I always get the noise and the occational of freezing. I read a lot of articles online from other Windows 7 users, indicating the same problems, so I have to believe that this is a problem with Windows 7 itself. If you go on Bing and just type in Windows 7, this site and others coming, talking about sound and freezing problems. What is the problem with Windows 7 and what is Microsoft going to do to correct the problem? I often have to connect my laptop to my TV for playback of movies, but the noise is very discouraging. Help!

  • STOP the iMac conversion of RAW video files to import

    I use iMac OS X Version El Capitan 10:11:6 and working in Lightroom CC.  I shoot video Time lapse on NIKON D500, in RAW and when I connect the camera to my iMac to import video files, the video file convert .mov files and that's it.  I want to change using Lightroom and LRTimelapse 4 Pro, and I need the file raw like blow, NOT a conversion. I can't understand how to solve this problem.  I think I should be able to disable the automatic import on my iMac, and then load the files video raw directly in LRTimelapse.  However, I can't have a way to disable the automatic import on my iMac.  Can anyone enlighten me here?  I'm going around in circles and it becomes very frustrating! Thank you!

    Jay anneb97695892 says:

    In fact, I had pretty good stuff in Aperture priority, emphasizing locked. I knew something, but not enough! Day was simple and turned out great. I tried to capture the Sunrise with a subject well lit at the forefront. Nothing is more difficult! I thought I'd try editing to fix. When I said automatically, I just wanted to say that I used the easiest way to create, (there is no Auto Mode on the D500), I was referring to using the time parameter. In any case, I feel educated now, so I can't wait to try it!

    I use LRTimelapse, and basically, you have two choices here:

    • The Time Lapse movie for your D500 parameter will create an all over time in camera. It is the best way to create a period of time, especially if the camera is good to smooth out changes in exposure. But if you use this option, there is very little Lightroom can do, and nothing LRTimelapse can do to change this time, because the film is already over.
    • Setting the interval for your D500 can save raw images full size, instead of compressed video images. You can load those in LRTimelapse for editing and management in Lightroom. LRTimelapse is a great software, and it allows you to apply the full power of changes at the level of the Lightroom raw to a sequence of time. This works best if you are already experienced with Lightroom processing raw and library functions. If you use this method, I strongly encourage you to read the tutorials on the LRTimelapse site because the steps must be followed closely. If you do this, you can be rewarded with some smooth, spectacular results and much more flexibility than if you did it all behind closed doors. (For example, the ability to add the reduction of noise of Lightroom and local adjustments, or pan a 2K or 4K of cultures throughout the entire framework believed). I am an experienced user of Lightroom and it still took me a while to learn the ins and outs of LRTimelapse, but if you need power and options LRTimelapse is well worth learning.

    If you are just getting started with the time, the best thing to do is to use the setting of film time in camera for awhile. See how you like it and make a list of things you wish you can change. Then start practice with the interval of definition, loading of raw in Lightroom and LRTimelapse images and make changes to your sequence before generating the final film. Just be aware that generate the previews of LRTimelapse and the final movie can take a lot of power, disk space and processing time.

    Depending on your problem, you can try to convert the types of video files supported in WMP 11 to read the files.

    For more information, you can consult the following article:

    Play an audio or video file: frequently asked questions

    Note: This also applies to WMP 11 in Windows XP.

    You can use your favorite search engine to download and install third party converter to play the video.

    Note: The use of third-party software, including hardware drivers can cause serious problems that may prevent your computer from starting properly. Microsoft cannot guarantee that problems resulting from the use of third-party software can be solved. Software using third party is at your own risk.

  • Windows Media Player - no audio during video playback

    Windows media player

    I am running Windows XP.  Windows Media Player opens successfully, I have audio but not video.  I tried to reinstall, update etc.  Still nothing.

    Hi jeffwebs,

    1. did you of recent changes on the computer?

    2 when was the last time it was working fine?

    3. you receive an error message during playback of video files?

    4. What if the problem occurs with all video files read using Windows media player?

    It is likely that the codec is correct / encoder is not installed or is installed but has been corrupted by another program.

    A codec is a software to compress or decompress a digital media file, such as a song or a video. Windows Media Player and other programs use codecs to play and create digital media files.

    A codec can consist of two components: an encoder and a decoder. The encoder performs the compression function (coding) and the decoder performs the decompression function (decoding). Some codecs include both components and some codecs only one of them.

    Follow the steps listed in the section below to download codecs for this problem.

    NVIDIA has a new driver from 3 March, do not know if you have it.
    If you do not have this version, please download and install the current version of the driver.

    If you already have the current version, it would be more useful to run a boot for

  • Windows 7 64 bit computer crashes when loading flash games or during video playback, forcing a manual reboot.

    My computer freezes completely at random times while playing the flash games or watching videos. In this case the mouse and keyboard stop working. If this happens during the video with sound, it makes a noise very loud signal blocked by speakers that continues until I restart the computer. The only way to recover is to manually restart the computer with the reset button.
