This is not clever, because i checked both libx264 and libx265 and both 
of them has same behavior like i proposed in patch.

Also explanation of this function is than wrong:
{ "forced-idr",   "If forcing keyframes, force them as IDR frames."}

There is nothing about disabled forcing keyframes at all.

So we have two options:
1. We should change it in NVENC
or
2. We should change it in libx264 and libx265
