2. use mediasdk_sys_analyzer.exe says 1.8 HW not support
I use CPU: Intel(R) Core(TM) i7-3770 CPU @ 3.40GHz
so, which cpu should i update to ?
Some code is shared between the samples for Windows and Linux. The vaapi include files are part of Media SDK for Linux Servers and not part of the Windows releases. LIBVA_SUPPORT is not defined on Windows.
For mediasdk_sys_analyzer, the highest API level available for HW acceleration is 1.7 for this release. As is often the case with Media SDK, the software implementation comes first to provide a functional preview. Code can be developed for the SW implementation and in most cases it will run without changes when the HW implementation becomes available. Hardware support for 1.8 features is under development and will be part of a future release.
