Demuxing and Remuxing an h264 stream that uses frame doubling to pulldown 59.9401 to 30000/1001 causes media info to report the incorrect fps rate. File plays correctly but causes strange behavior in other players. When set to 29.976, media will play at 30000/1001 but media info will report a 15000/1001 rate

After playing around with this some more, I found out that mediainfo reads the video stream as half the framerate due to the frame doubling. In this case, tsmuxer should set the container framerate to half of what the video stream framerate is set to.
