I apologize.  The above should be:

   audio_time = audio_st->pts.val * av_q2d(audio_st->time_base);
   video_time = video_st->pts.val * av_q2d(video_st->time_base);
   while ( audio_time < video_time )
   {
      write_audio_frame(oc, audio_st, img);
      audio_time = audio_st->pts.val * av_q2d(audio_st->time_base);
    }
    write_video_frame( oc, video_st, img );

where img is the class container for audio and video.
