[Libav-user] How to set avcodec_open2 to set ((MpegEncContext *)(avctx->priv_data))->fixed_qscale = 1?

I'm trying to push a stream to a server with ffmpeg. I debugged the ffmpeg code, and found that when avcode_open2 returned, the ((MpegEncContext *)(avctx->priv_data))->fixed_qscale = 1. That to say, when video stream was handled, certain offset of avctx->priv_data pointer (just fixed_qscale field) was set to 1.
I tried to find which parameter would lead to this result, but failed. If fixed_qscale was not set to 1, program will not run to "Error evaluating rc_eq "<null>"" problem. Can someone give an advice?
Thanks for help
