Operating System : Windows 7
Hardware : i7 - 4770
ffmpeg sample code for hardware encoding is running fine.
But when I merge this code in my application h264_qsv takes only CPU power. It didn't use GPU.
Haswell is little bit old, I am not sure if runtime + media sdk combination can support the hardware. So either tell me the MSDK version or you get a new processor and try the latest MSDK to see if it works.
