Comment (by heleppkes):

 specifying level only adds constraints, it does not lift them. So if you
 don't specify a level, it'll use the highest required for your content.

 That means that if you want to encode 5.2, there is no need to specify a
 level, since it'll automatically pick one.

 The only reason to specify a level is if you want to constraint yourself
 to a specific level and not accidentally go over it.

 The lack of th 5.2 level in nvenc_h264 should still be fixed, but its not
 necessarily required to specify it.
