[Libav-user] How to set moov_size?

I'm trying to set the moov_size when recording to a .mov file, however I can't figure out how to do this properly.

For example this doesn't work:
  output_format = av_guess_format("mov", NULL, NULL); 
  output_context = avformat_alloc_context();
  output_context->oformat = output_format;
  codec = avcodec_find_encoder(CODEC_ID_H264);
  video_st = add_video_stream(output_context, codec, p->parent->parent);

  /* This does not work */
  av_opt_set_int(&output_format->priv_class, "moov_size",120000, AV_OPT_FLAG_ENCODING_PARAM);

At the moment I'll post process the movies with qt-faststart, but it would be nice if I can skip this step.
