Intel Engineer Ports QuickSync Video Decoding to FFDShow
 

An Intel engineer by the name of Eric Gur started an AVSForum thread indicating he had begun work on enabling Quick Sync support in FFDShow's video decoder. Quick Sync is typically known as Intel's hardware accelerated transcoding engine found in Sandy Bridge, however there are both encode and decode aspects to the engine. Gur's work focuses on the latter.

To access Intel's hardware video decode acceleration application developers typically turn to the DirectX Video Acceleration (DXVA) API. Sandy Bridge's hardware decode engine interfaces with DXVA and can return decoded frames not run on the x86 CPU cores. As we've lamented in the past, open source DXVA decoders haven't typically worked all that great for Sandy Bridge (or previous generation Intel GPUs, for that matter). FFDShow users have often avoided DXVA solutions as they can't be used with any custom post processing FFDShow filters.
