Answers for the questions raised during the April session of our Introduction to High Performance Application Development for Intel® Xeon® & Intel® Xeon Phi™ processors class have been assembled.  There were some duplicates and other questions we couldn't decipher, either because of the wording or because of implied context that was not spelled out.  We tried to address the rest, which appear below:

This tutorial transcode sample uses the same approach as the previous OpenCL* frame processing samples. But in this case the integration with Intel® Media SDK utilizes the SDK user plug-in concept to ensure asynchronous behavior for optimal performance.

For optimal performance, stream transcode and frame processing are both executed using Intel® HD Graphics, featuring efficient surface sharing via the OpenCL 1.2 Khronos DX9 Media Surface Sharing extensions.

This tutorial sample is similar to the “simple_6_decode_vpp_postproc” sample but instead of using VPP to post process the frames, the sample efficiently integrates with Intel OpenCL* SDK to enable custom frame processing executed on Intel® HD Graphics.
