Comment (by jkqxz):

 Can you offer more detail about the platform you are using?

 The command as-is doesn't work for me with current libmfx on Skylake
 because AVBR without look-ahead isn't supported there.  Either re-adding
 the look-ahead or adding a maxrate both work (with AVBR+LA and VBR
 respectively), and have full hardware acceleration.

 Summary of the bug:
 QSV h264_qsv encodes via CPU instead of GPU (without HW accel.).

 In output "[h264_qsv @ 0x352d1e0] Encoder will work with partial HW
 acceleration"
 Test via Intel Media SDK passed OK.

 Problem is on version: N-83042-g107b306 (and some older)
 But in older version N-82007-g1a9513b qsv works fine (I see load in
 intel_gpu_top).


 How to reproduce:
 {{{
 % ffmpeg -y -v debug -i
 "udp://@239.255.0.103:1234?fifo_size=100_nonfatal=1" -map v:0
 -profile:v main -c:v h264_qsv -look_ahead 0 -an /a.mp4
 }}}
