HI All,
I am posting this query here as I didn't find any separate forum for Vaapi based decode/encoders.
Actually, 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
https://01.org/linuxgraphics/downloads/2015q2-intel-graphics-stack-release
MY vainfo-
libva info: VA-API version 0.38.0 libva info: va_getDriverName() returns 0 libva info: User requested driver 'i965' libva info: Trying to open /usr/local/lib/dri/i965_drv_video.so libva info: Found init function __vaDriverInit_0_38 libva info: va_openDriver() returns 0 vainfo: VA-API version: 0.38 (libva 1.6.1) vainfo: Driver version: Intel i965 driver for Intel(R) CherryView - 1.6.1 vainfo: Supported profile and entrypoints VAProfileMPEG2Simple : VAEntrypointVLD VAProfileMPEG2Simple : VAEntrypointEncSlice VAProfileMPEG2Main : VAEntrypointVLD VAProfileMPEG2Main : VAEntrypointEncSlice VAProfileH264ConstrainedBaseline: VAEntrypointVLD VAProfileH264ConstrainedBaseline: VAEntrypointEncSlice VAProfileH264Main : VAEntrypointVLD VAProfileH264Main : VAEntrypointEncSlice VAProfileH264High : VAEntrypointVLD VAProfileH264High : VAEntrypointEncSlice VAProfileH264MultiviewHigh : VAEntrypointVLD VAProfileH264MultiviewHigh : VAEntrypointEncSlice VAProfileH264StereoHigh : VAEntrypointVLD VAProfileH264StereoHigh : VAEntrypointEncSlice VAProfileVC1Simple : VAEntrypointVLD VAProfileVC1Main : VAEntrypointVLD VAProfileVC1Advanced : VAEntrypointVLD VAProfileNone : VAEntrypointVideoProc VAProfileJPEGBaseline : VAEntrypointVLD VAProfileJPEGBaseline : VAEntrypointEncPicture VAProfileVP8Version0_3 : VAEntrypointVLD VAProfileVP8Version0_3 : VAEntrypointEncSlice VAProfileH264MultiviewHigh : VAEntrypointVLD VAProfileH264MultiviewHigh : VAEntrypointEncSlice VAProfileH264StereoHigh : VAEntrypointVLD VAProfileH264StereoHigh : VAEntrypointEncSlice VAProfileHEVCMain : VAEntrypointVLD
I tried to developed a decoder for only one I-frame using vaapi API based on this link.
http://cgit.freedesktop.org/libva/tree/test/decode/mpeg2vldemo.cpp
But my output is not coming proper. I am seeing blocky patches in output yuv...

Hi Sumit,
There is a forum for the linux releases from where you have downloaded the libva, driver and kernel at https://01.org/linuxgraphics/forum, you can post in the graphics installer discussion page, where open source projects and Intel graphics for Linux is discussed.
Thanks,
Surbhi
