Unfortunately, I'm not sure how to answer this.  Here is what ffmpeg
seems to report when it reads the input file:


Input #0, mpegts, from '4101_20110211115900.mpg':
  Duration: 01:06:02.95, start: 94093.518944, bitrate: 15680 kb/s
  Program 1
    Stream #0.0[0x21]: Video: mpeg2video, yuv420p, 1920x1080 [PAR 1:1
DAR 16:9], 14918 kb/s, 35.59 fps, 29.97 tbr, 90k tbn, 59.94 tbc
    Stream #0.1[0x24](eng): Audio: ac3, 48000 Hz, 5.1, s16, 384 kb/s


Also, is there a flag I can pass to ffmpeg to get it to suppress the
encoding progress messages?  The line breaks are non-standard and
causes my mythbackend.log file to be hard to read.  Or is there I way
I can get it to spit out the messages less frequently (say, once every
10 minutes)?

Thanks!
