In that case, why not set ffmpeg's default to 0, which would mean
"auto". As 0 is not possible as soon as inter frames are used, this is
easily identifiable. Unfortunately, all affected encoders using it (ie
except nvenc, which would use the same convention) must be modified to
detect and change that 0 back to 1.
