Could you please provide some additonal info regarding the version of Media SDK, Media Checker and Intel driver you are using. Have you made any other hardware configuration changes to your machine, such as enabling or adding discrete graphics card?
Some things you could try also:
- Try running sample_decode.exe to decode a stream without using a batch script or Media Checker. Look at the information regarding the decode operation that gets printed right after starting decode. "MediaSDK impl" should tell you if it is running in HW or SW. What do you get?
- Try uninstalling Media Checker then run the workload again. Media Checker may be interfering with Media SDK
from the information you provided (thanks!) it certainly looks like this is a Media Checker issue.
Did you try to uninstall then reinstall Media Checker?
If that does not work I suggest you contact the Software Partner Program support that is responsible for the Media Checker product and please report your issue there for them to debug. http://www.intel.com/partner/support
