You can experience one of these issues while using Adobe Flash Player:
- Video does not display
- A black or white box replaces the video
- Colors are splotchy
- There’s a green line splitting the player in two
- The seek/navigation bar is missing or displaying incorrectly
- The video stops playing when you change the resolution (especially in full screen mode)
Flash Player 10 and later can use your system’s graphics hardware to accelerate video decoding. Flash Player 10.2 and later can also accelerate video presentation on some sites, accelerating all aspects of video playback. If you are experiencing video playback issues in Flash Player, it is possible that your video adapter driver software has incompatibility issues. Follow the steps in this article to troubleshoot these issues and help provide Adobe with information that can be used to improve Flash Player.
See the following videos in an HTML5 supported browser.
If you can see the HTML5 video properly, but can’t see the non-HTML5 video, there could be an issue with Flash Player. If you can’t see both the videos, it can be an issue with your device drive.
If you experience problems when playing back video, follow these steps:
Try disabling hardware acceleration. Right-click the Flash Player logo below, choose Settings from the context menu. Deselect Enable Hardware Acceleration (on the Display tab), then and click Close.
See the sample stage videos from the Adobe site.
If disabling hardware acceleration solves the problem, it's possible you have a video card driver-specific issue. To help Adobe address the issue, follow the directions below to report the issue.
After updating the driver (and restarting your computer as needed), reenable hardware acceleration in Flash Player (following the steps above). Check to see if the video playback issues have been resolved. If it has not been resolved, follow the directions below to report the issue.
By filing a report or bug, you can help Adobe work with driver manufacturers to address issues. Follow the instructions below to provide your video adapter driver information. Also provide a clear and detailed description of your issue with the information that Adobe requires to investigate.
Go to the Start menu and type "dxdiag" in the search box. Or select Run and type "dxdiag" in the text entry box that appears.
When the DirectX Diagnostic Tool has launched, click Save All Information to save the diagnostic report to a file named "DxDiag.txt". Save this file to your Desktop so that it is easy to locate. (Optional: If you would like to quickly view your video card name, manufacturer, and driver version, you can select the Display tab.)
Attach the DxDiag.txt file to your bug report, as described below.
Select the Apple icon to expand the menu and select About this Mac.
Choose File > Save to save the system information to a file. If you would like to view your driver version number, select Graphics and Displays.
