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.
