Thanks. Worked like a charm. If only it were this easy to do this on Windows...
How about my second question below? Is there a way to know whether openh264 was used rather than libx264?
>I did NOT use either --enable-gpl or --enable-nonfree. I had been using libx264 up to now but want to make sure I will be using Cisco's OpenH264. The way I select H264 is with the code      avformat_alloc_output_context2 (&oc,NULL,"mp4",NULL);
      oc->oformat->video_codec = AV_CODEC_ID_H264;
