Does Sandy Bridge execute Media SDK decoder in GPU or in other device?Thanks.

For more complete information about compiler optimizations, see our Optimization Notice.


When the Media SDK session is initialized with option to allow hardware acceleration, and the Intel 2nd Generation Core platform includes properly installed graphics drivers that support the Media SDK API, supported video decode operations will be executed on Intel's integrated graphics adapter.


Hi Tony,

Thank you! Is Intel's integrated graphics adapter same as integrated graphics processor? Intel Integrated graphics processor includes multiple EU, is there a way to balance resource (computation) among the EUs?


Yes, 'adapter' is a Microsoft Operating system term. I've found that some think of 'processor' as only 'EUs' and the video decode task uses more than programmable EUs. Please see http://software.intel.com/en-us/articles/quick-reference-guide-to-intel-processor-graphics/ for a list of the many features of 2nd Generation Intel Core Processor Graphics (HD Graphics), including Intel Clear Video HD Technology.

For optimizing the balance of resources beyond the default behavior of the Intel Media SDK you may want to view this whitepaper:http://software.intel.com/en-us/articles/using-intel-graphics-performance-analyzer-gpa-to-analyze-intel-media-software-development-kit-enabled-applications
