Video Not Playing? Check Your Overlay Options!

Intel Graphics Media Accelerator Utility

Intel Graphics Media Accelerator Utility

The problem: This recent discovery–rather, rediscovery– was the final straw, causing me to reformat and reinstall a fresh copy of Windows on my laptop. I had been meaning to do it for a long time (something like 2 years), but I never found myself in the mood. However, something came up, and I needed to play a video on my laptop, which hadn’t worked for a few months (sound worked, no picture). On previous occasions I reinstalled the graphics driver, I reinstalled all the required codecs, and I tried playing the videos on Windows Media Player, VLC, Windows Media Classic, and Quicktime. Flash based videos from Hulu and YouTube worked wonderfully, just nothing else. So, on this particular occasion, I decided that it was far more difficult to troubleshoot the video problem than to just wipe the sucker.

But, the problem returned. $%&#!!

The solution: In a rare moment of serendipity, I recalled the Intel driver for my laptop’s integrated Intel 915GM Express Chipset installs a utility. This utility, the Intel Graphics Media Accelerator, includes a interface for adjusting the color, contrast, and brightness of a hardware accelerated video overlay. Years ago, I had the same problem where I eventually discovered (likely serendipitous as well) that, for reasons unknown to me, the options for the video overlay had been set to zero, so the overlay would appear pure black. So, the picture had been there the whole time, it had just been blacked-out. Returning the values to default will set everything right.

Now, knowing what to search for, I’ve found that it’s a known issue with the latest version of the driver, and can be corrected by downgrading (meaning Intel no longer support the driver, and you’re stuck with it.).

For more information, see the official Intel support page.

  • Hi,

    thanks for that hint! Here it was even worse – the new version of the driver, which I had installed on my laptop caused the laptop to crash when changing to the “DVI output scheme” – I even reinstalled WinXP to solve that issue, no success. Now when trying to troubleshoot the overlay problems, I stumbled upon your hint and downgraded the driver – and it fixed the crashing as well! Nice!

    Cheers,
    Sascha

  • Yikes! What a hassle! It’s pretty annoying that we have to keep our laptops at a downgraded state because the newer drivers cause instability!

    I didn’t mention this in the post,but the overlay options would get set to zero when I used the shortcut to change the output (rather than the built-in control panel option for Windows display settings). I see your issue was worse (causing a crash!) when doing something very similar.
