I have a Linux box and would like to encode some videos with ffmpeg. I have heard that my CPU (a second gen core i5 processor) has hardware support for h.264 encoding.

Is it possible to get ffmpeg to use this, and if so how?

Just some general thoughts: Those processors are very new and for hardware support to be supported by software takes time. Compilers would need to support it and then later programs too. My Google skills could be bad, but I couldn't find anything on hardware support for Intel® Quick Sync Video on FFMPEG or GCC. –  AndrejaKo Mar 4 '11 at 15:40

No, it is not. FFMPEG does not support Intel's QuickSync technology. In order to use QuickSync a program has to go via Intel Media SDK which is not available for Linux.

other parts of ffmpeg are Windows only, so I suppose it could add support with enough effort –  rogerdpack Jun 11 '12 at 21:20

x264 access QuickSync without using MediaSDK. Intel reached them and they mutually helped each other to accomplish that (google for "x264 QuickSinc). It may be possible to capitalize on their effort and bring it to ffmpeg...
