    Hi Aii,
    i got a reply form this forum  that Intel Media SDK is not supported for NUC -Intel(R) Pentium(R) CPU N3700. So, I have taken libva 1.6, Kernel 4.2, vaaps-driver  from 
    I tried to  developed a decoder for only one I-frame using vaapi API based on this link.
    But my output is not coming proper. I am seeing blocky patches in output yuv.
    But my setup with kernel 4.2 and old Valib and Vappi is working fine.I am getting correct decoded I-frame.
    Even if  this I frame decode worked fine, how can i build a full decoder using only Vaapi Api. How  one will handel B-frame and P-frame in decoding,
    If you all have any parser code to extract header info at slice level then plz share.

  • Hi - this sounds more like a topic for the advanced forum, I suspect you'll have more luck there - I'll see if I can get this question moved there (or you could start a new thread there if you're pressed for time).
