I have a 1600x1200 4Mbps H264 video stream. When I use the sample_decoder.exe from MediaSDK 2012 to decode this video file, and add the "-hw" switch to the command line, decoding is still dispatched to the CPU software (according to GPA Media Performance window). I even checked by MFXQueryIMPL and it returns MFX_IMPL_HARDWARE. If I play this video file in media player, I can see in GPA that it's decoded by GPU HW. If I use sample_decoder.exe on a smaller video (e.g. 1920x1088), it's scheduled to GPU.
Doesn't MediaSDK support hw decoding of large frame size?Since media player can use GPU HW, how to enforce hw decoding of this video stream in MediaSDK?
