Hello, I am hoping somebody at Intel can answer a few questions on a video research application. The following questions are in regards to QuickSync H.264 and MPEG2 decoding on the Sandy Bridge Gen2 processors. 1. I currently use a software based H.264 and MPEG2 video decoder which allows me to extract the stored per-macro block QP values. I have not found a way to do this using the Media SDK. Any suggestions on how I might use the Media SDK to do this? 2. In the Media SDK decoders, where does the bitstream parsing where QP first becomes available happen? On some GPU architectures decode bitstream parsing appears to mostly occur mostly on the host processor, so, in fact per-macroblock QP values first becomes available on the host-CPU, not actually in the GPU. Is this how Sandy-Bridge accelerated decoding works? Does the host CPU do the bitstream parsing to the point where per-macroblock QP is decoded? 3. Is there released source code for either H.264 or MPEG2 Quick Sync decoding using SB that would allow me to retrieve the per-macroblock QP values? I have been experimenting with the SDK on Sandy Bridge, and love the performance. Thank you for any answers to these questions. Cameron
