Two additional ffmpeg code lines 3) and 4 for HEVC QSV follow. These are 
not correspondingly to 1) and 2), but working codes I have tested before.
Log files via email.

3)
1080i HDV-> HEVC_QSV
--------------------
ffmpeg -hide_banner -loglevel debug -hwaccel_output_format qsv -i 
hdv09_04.m2t -pix_fmt p010le -c:v hevc_qsv -profile:v main10 
hdv09_04_hevc_qsv.mp4 > hdv09_04_hevc_qsv.log 2>&1

4)
HEVC qsv decode + HEVC qsv encode
---------------------------------
ffmpeg -hide_banner -loglevel debug -hwaccel_output_format qsv -c:v 
hevc_qsv -i h265_yuv420p+opus.mp4 -c:v hevc_qsv 
hevc_yuv420p+opus_qsv.mp4 > hevc_yuv420p+opus_qsv.log 2>&1
