Comment (by terran):

 The regression seems to be related to the following change:

 {{{
     x4->params.rc.i_qp_min                 = avctx->qmin;
     x4->params.rc.i_qp_max                 = avctx->qmax;
     x4->params.rc.i_qp_step                = avctx->max_qdiff;
 }}}

 became...

 {{{
     if (avctx->qmin >= 0)
         x4->params.rc.i_qp_min          = avctx->qmin;
     if (avctx->qmax >= 0)
         x4->params.rc.i_qp_max          = avctx->qmax;
     if (avctx->max_qdiff >= 0)
         x4->params.rc.i_qp_step         = avctx->max_qdiff;
 }}}

 I imagine there may be other related changes but removing these eliminated
 the bug for me.
