VPP HW impl blurs text image during color conversion from BGRA to NV12

[Ramashankar]

With reference to my previous post: https://software.intel.com/en-us/forums/intel-media-sdk/topic/657754

VPP HW implementation is blurring text images when I convert BGRA (RGB32) frames into NV12, whereas VPP SW implementation works fine in same scenario.

This issue can be easily reproduced with Intel Media SDK Samples 2016 6.0.0.142 and Intel(R)_Media_SDK_2016.0.1 also. Use following command lines:

1. sample_vpp -i VppIn.bgr -sw 1920 -sh 1080 -scc rgb4 -dw 1920 -dh 1080 -dcc nv12 -lib hw -o VppOut_HW.nv12

2. sample_vpp -i VppIn.bgr -sw 1920 -sh 1080 -scc rgb4 -dw 1920 -dh 1080 -dcc nv12 -lib sw -o VppOut_SW.nv12

Source frames, comparison results and environment details are attached here.

As per discussion on my previous post, root cause was diagnosed at intel driver, but there are no further updates after that. So please update.

Hi,

Please let me know if above issue has been fixed or going to be fixed in any future release? I raised this issue initially around a year ago and it was reproduced by intel team also, but still got no final reply or solution. Please suggest.
