Comment (by jkqxz):

 From the code at
 <http://git.videolan.org/?p=ffmpeg.git;a=blob;f=libavcodec/qsvenc.c;h=5eb506fb76224d48e19bc66d3dc67fe9a5c86184;hb=HEAD#l361>
 it looks like this works, though I've no idea whether libmfx will actually
 respect the level you pass in for encode.

 However:

 > {{{
 > -level 4.1
 > }}}

 This wants the level_idc value rather than the human-readable string name:
 try 41.
