720P H.264 video decoding performance Yesterday I got two test H.264 ES stream files from one of my colleague. One was encoded by Main Profile, the other was encoded by Baseline Profile. Weired thing is decoding the Main Profiled file seems much more fast than the Baseline Profiled file. To […]
3 After finished my first phase of GPU – Intel Media SDK research, now it’s time to get into libva, my goal is to get a set of performance test report for both MSDK and libva, so that we can finally choose one of them, or both of them for product […]

It’s a test report of current/latest version of kdvcodec_msdkdec which based on the latest version of Intel Media SDK(4.0.024-HSW). There is a known issue, NV12 to YV12 (or YUV420P) conversion, which is very low in efficiency. Here are the details.

About The main motivation for VA-API (Video Acceleration API) is to enable hardware accelerated video decode/encode at various entry-points (VLD, IDCT, Motion Compensation etc.) for the prevailing coding standards today (MPEG-2, MPEG-4 ASP/H.263, MPEG-4 AVC/H.264, and VC-1/VMW3). Extending XvMC was considered, but due to its original design for MPEG-2 ?MotionComp […]
