Does your H323 terminal support AAC LC or AAC LD?
This thread is direct forward from Microsoft MSDN website: http://technet.microsoft.com/zh-cn/aa965245 Easlier in this month, I was researching hardware video encoding/decoding supports for Linux base environments, which involves Intel Media SDK & VA-API(libva). Happen to see this DXVA related post in MSDN, so I decided to copy it to my blog. […]

Performance tests of Intel Media SDK (4.0.024-HSW) – Multithread decode
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 […]
