    i'm trying to use webcam in skype or win8 camera app but it's not working.
    the webcam led is on but instead of video picture i see black screen.
    i tryed to delete driver(21/06/2006, 6.2.9200.16420 by microsoft) installed automatically by win8 and reinstall it again after restart but still nothing.
    win8 shows that the driver was installed correctly and device manager says webcam is working properly and no need to update it.

    It was OK with Windows 7.
    There is no any camera driver on Compaq website, there is only Youcam software which I installed already.

    Please help

    Mine works in skype. Just not in the camera app from Windows Store. On 8, it worked whether I had the camera manufacture drivers/software installed or not.

    If I uninstall the driver, windows installs it automatically. I don't have any other driver If I remove the webcam it's installing again.

    I have the same issue with a Microsoft Cinema webcam. Yet the cheap creative cam built into the laptop works fine. I suspect it will take time to sort out driver issues.

    But if anyone finds some other solution please don't forget to come back and tell us!

    For all those having issues with the modern UI apps...
    Have you guys tried uninstalling them, and re-installing them from the Windows Store?
    It could be that they are not being auto-updated since Win8.1 isn't officially out yet.

    I have been investigating this. I don't have a solution yet.

    I think it might be a Codec issue. For Metro Apps Microsoft has replaced the normal Windows DirectShow Codec chain with Media Foundation which uses internal Microsoft Codecs.

    For power efficiency, Microsoft seems to prefer doing a hand-off to the video driver when it can which makes for yet another big mess.

    Windows Media Player should also default to using Media Foundation (but that can be changed unlike Metro apps) so Media Player can be a diagnostic in some cases.

    Microsoft is pushing for H.264 and AAC so those are implemented internally in Media Foundation. So my hypothesis is that they "tweaked" some Codecs for 8.1 and/or offloaded more of it to crappy video drivers to produce the current mess.

    Hence updating video drivers may help and also may not be of any help depending on the computer and the video formats being used.

    If anyone knows of a diagnostic tool for Media Foundation, please post...

    Further investigation...

    Fact:

    There is currently no method to update codecs for Windows 7 or 8 or 8.1 for any programs that directly use the Media Foundation API

    This has not previously had an impact on people because almost all programs that use media on Windows will have an option to use DirectShow which has the ability to search a graph of possible codecs installed by various codec packs etc.

    The Media Foundation ONLY uses codecs supplied by Microsoft.

    Individual apps that use the Media Foundation can provide a hook to use their own codec but it is only available to that app.

    All "Windows Store/Metro/Name of the Month for Windows App" Apps must use Media Foundation

    The "native" (i.e. most compatible) video format for Media Foundation is Container: MP4, Video Codec: H.264, Audio Codec: AAC or MP3 (Surround to be added at some future point)

    Speculation:

    1. The additional problems that seem to be surfacing with 8.1 are possibly due to the new Skype deep integration into Windows 8.1 which means that Skype for the desktop and possible other Microsoft products for the desktop will also bypass DirectShow and exclusively use Media Foundation

    2. There seems to be a stronger expectation by Microsoft that the computer will have a recent model video card and as part of extending battery life, the more efficient GPU is preferred for video rendering which at least in my single case causes Media Foundation to completely fail on my AMD 4870m laptop video.

    I have tried my camera with the Skype App, Skype for Desktop, and in my Logitech webcam software. All of which work. It is only the camera app that does not function. I will attempt to fix by uninstalling/reinstalling. That is if it is uninstallable.
