  1. Hello,

    I can't get to the bottom of this old problem, and I don't know what else can I try before reinstalling Windows. I've tried searching for solutions in vain, as similar problems are many, and all have various roots. So I turn to you for help:

    Symptoms:
    They change from day to day and from website to website. I can't explain it. On some days it works without problems, on others it behaves likes this:
    Vimeo: complete black, no sound, position marker not moving, system frozen for several seconds
    Facebook videos: either black and whole system frozen for a few seconds, or very dark, pixelated but playing, and then it turns to normal in ~5 seconds. (Example of playing, but dark video: http://imgur.com/V8bIafY )
    Youtube: not affected, or very rarely. 99% of the time it works, 1% black screen with sound, gets back to normal in ~15 seconds.
    other flash websites: some of them also turn black and back.

    System:
    Win10 x64, all browsers are affected.

    Additional info:
    I *think* it all started when I installed Potplayer. It might have installed some video drivers that could do this. I've tried clearing browser cache, different browser, disabling HW acceleration, removing and reinstalling the player, etc.

    Any idea of how to fix my codecs would be greatly appreciated.
    If you need any additional details to debug, tell me and I'll update with info.
    Thank you!

    How do I do that? Are there some plugins for all browsers? Don't they take care of themselves?

    did you try a boot up to safe mode
    and then system restore to a date when everything worked correctly

    also
    i've learned from experience to run an install monitor like Ashampoo installer/uninstaller
    for every install

    very helpful if some piece of software changes things,
    it records all file entries and regestry changes

    using the uninstall removes those changes and resets things

    sometimes saves the need for a system restore, or file replacement

    You can try ccleaner. It is free, and it can helps in such problems. If I were you I would at least try it.

    I've long since forgotten what I did to solve my online video playing problems.
    Just guessing here!
    Abobe Flash?
    ffdshow?
    VLC?
    x264vfw?

    I am hopeless. If all browsers are affected, there must be some major problem. Try install in firefox html5-video-everywhere add on. It supports sites you mentioned, so maybe it will help. But I really dont know.
    Sorry

  12. Thanks for your help so far!
    Can you recommend a forum where I could ask about this? Advanced video/codec stuff, how to debug it?
