Component:  avformat                             |     Version:  git-master
 Keywords:  avi aac after av_write_header        |  Blocked By:

-------------------------------------------------+-------------------------
 Source (mp4/aac):
   Duration: 00:00:58.40, start: 0.000000, bitrate: 1154 kb/s
     Stream #0.0(eng), 159, 1/32000: Audio: aac, 32000 Hz, stereo, s16, 46
 kb/s

 Copy stream to mov or mp4:
     Stream #0.0(eng), 0, 1/32000: Audio: aac, 32000 Hz, stereo, 46 kb/s

 Copy stream to avi:
    Stream #0.0(eng), 0, 4/125: Audio: aac, 32000 Hz, stereo, 46 kb/s

 Output AVStream->time_base:
   before av_write_header() - 1/32000 (good)
   after  av_write_header() - 4/125   (wrong)
