Comment (by Balling):

 What? YUVView? Why?? Just use ffplay.

 Yeah, there was some bug in h264_qsv, because if you will try your command
 now, and will then ffplay p010 file with:

 {{{
 ffplay -video_size 1280x720 -pixel_format p010le -f rawvideo -i
 P010_out.yuv
 }}}

 it will play fine (except that it defaults to BT.709 matrix with sRGB
 primaries, as no metadata in the yuv file, but it is correct!! the avc
 bitstream will have the same values).

 On the other hand AFAIK my old CPU does not have modern QSV stuff. I am
 not sure. In that case just omit -c:v h264_qsv or add instead -hwaccel
 cuda.
