Thanks for the suggestion, I've extracted duplicated code to amfenc.c file,
but can't extract the whole smart_access_video option, because there are
some differences between av1 & hevc/h264 encoders while set low latency
mode.
In addition, I've added a more detailed description for SAV option, I hope
it will be enough for understanding.
