software encoder the final result are garbage of colors, it seems
something is wrong with ffmpeg

it Works but software is garbage, can u address this bug to ffmpeg
developers to fix this issue? This Works on sample_multi_transcode on
Windows 10 Pro x64 with git Media SDK

I tried and dont work, check this problem No hw context provided if i
remove hwaccel qsv option, maybe we need a option in ffmpeg to work in
system memory wit hwaccel qsv option on

I'm using latest Intel Media SDK from GitHub
This pull request [samples] Correct vpp output bit depth according to
FourCC #1416 from Intel Media SDK git did the trick for
sample_multi_transcode working in hardware to convert from 8 bit to 10
bit, check the pull request from Intel Media SDK
