I have come across a problem here. I have two machines a i7 2600k on which the hardware decoding is working fine but the same code on a i7 4770k seems to decode like just a quarter of a frame for each frame. I am using SDK 2013 R2.
Another thing I noticed is that on the i7 2600k machine the DecodeHeader() is returning different values as follows
i7 2600k - mfx.FrameInfo.FrameRateExtN = 240000 mfx.FrameInfo.FrameRateExtD = 9600
i7 4770k - mfx.FrameInfo.FrameRateExtN = 50 mfx.FrameInfo.FrameRateExtD = 2
The one information decoded by 4770k is accurate as the frames are interlaced but it dosent return entire frames on 4770k.
Can you please let us know what tutorial/sample you are using? That will help us help you.
If you are using the simple_6_decode_vpp_postproc, the VPP out params specifies the output should be quarter resolution:
VPPParams.vpp.Out.CropW = VPPParams.vpp.In.CropW / 2; // Resize to half size resolution
VPPParams.vpp.Out.CropH = VPPParams.vpp.In.CropH / 2;
Anyway, some more information about your code would be helpful
The problem I had is been solved. The Problem was in assigning the memory to the VPP surface's components (i.e R, G, B, A). due to which the data was lost and only Quarter of a frame was being displayed. But i still dont understand how could it perfectly run on a i7-2600k. Anyways thank you.
