HI,
I am working with libVA and opensource vaapi driver to create Mpeg2 decoder.
But, when i am using open source i965_drv_video.so driver my output has some blocky look. However if i use media SDK iHD_drv_video.so there is no such block look in output.
I have attached images and vainfo of my setup. Plz suggest what could be the wrong.

hst_input_frame238.png ->> input image
hst_decoded_NUC_Ubuntu_iHD--> decoded by IHD driver --> no blocky look.
{
vainfo-for this setup
libva info: VA-API version 0.35.0 libva info: va_getDriverName() returns 0 libva info: User requested driver 'iHD' libva info: Trying to open /opt/intel/mediasdk/lib64/iHD_drv_video.so libva info: Found init function __vaDriverInit_0_32 libva info: va_openDriver() returns 0 vainfo: VA-API version: 0.35 (libva 1.3.1) vainfo: Driver version: 16.4.2.1.39163-ubit
