+Minimum frame-level Lagrange multiplier for ratecontrol (default: 2.0).
+Lavc will rarely use quantizers below the value of lmin.
+Lowering lmin will make lavc more likely to choose lower quantizers for
+some frames, but not lower than the value of vqmin.
+Likewise, raising lmin will make lavc less likely to choose low
+quantizers, even if vqmin would have allowed them.
+You probably want to set lmin approximately equal to vqmin.
+When adaptive quantization is in use, changing lmin/lmax may have less
+of an effect; see mblmin/mblmax.

Constant quantizer /\: constant quality encoding (selects fixed quantizer mode).
A lower value means better quality but larger files (default: 0).
