 Replying to [comment:7 thx4ever]:
 > 1 - Yes i have tried HEVC HW Encoder and it Works but when try software
 encoder the final result are garbage of colors, it seems something is
 wrong with ffmpeg
 > 2- Sorry for that but doenst matter what BRC i use, CQP-AVB-VBR on HW 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
 > 3- Yes sample encoder Works but i use alot ffmpeg right now

 Could you please share your sample encoder and sample multi transcode
 command line?

 I checked MediaServerStudioProfessional2017 release guide, it is said

 MAIN10 profile encoding/decoding and range extensions profile encoding can
 be done only with system memory at input and output on linux (SDK/driver
 limitation for video memory frames allocation)

 Thus means probally you should remove the "-hwaccel qsv" to make it is
 working in sytstem memory:

 ffmpeg-v verbose -c:v h264_qsv -i tikect_8065/sample_AVC.264 -vf
 vpp_qsv=format=p010le -c:v hevc_qsv -load_plugin hevc_sw -profile:v main10
 -preset:v veryslow -g 240 -refs:v 6 -bf:v 3 -flags -cgop -gpb 0 -q:v 18
 -vframes 5 -color_primaries bt709 -color_trc bt709 -colorspace bt709

 Please tried it and update the status.
