Comment (by Pljushevij):

 I was replacing scale_qsv like this and now all works perfect:


 {{{
 ffmpeg-4.4 -init_hw_device qsv=hw -filter_hw_device hw -c:v h264_qsv -i
 sailboat.ts -filter_complex
 "movie=alogo.png:loop=0,setpts=N/FRAME_RATE/TB[mv];[mv]hwupload=extra_hw_frames=10,format=qsv[watermark];
 [0:v]format=nv12,hwupload=extra_hw_frames=10,scale_qsv=w=1280:h=720[temp1];[temp1][watermark]overlay_qsv=x=(W-w):y=(H-h)/2:shortest=1"
 -c:v h264_qsv -b:v 3M -maxrate 3M -c:a copy -y -movflags +faststart test-
 ffmpeg44.mp4
 }}}


 But may you can help me make this by VAAPI?
