With mediainfo I see, that I need "-profile:v constrained_baseline 
-level 4.1":

This profile is only available with VAAPI encoder, see 
libavcodec/vaapi_encode_h264.c
or amfenc  encoder, see libavcodec/amfenc_h264.c

So I tried:

Unknown encoder 'h264_vaapi'

It seems, I use the wrong syntax. What is the correct syntax for 
'h264_vaapi'?
