Comment (by mliradelc):

 I found another workaround, this time it doesn't involve change the
 {{{config}}} file
 add this line when you compile ffmpeg:
 {{{
 '-gencode arch=compute_52,code=sm_52'
 }}}

 That will overwrite the default compute code version from 30 to 52, also
 can be changed to 35 to allow compatibility with older cards.
