Description

Before this commit https://github.com/FFmpeg/FFmpeg/commit/4cfb01d6ae545cec4a507113a6cbcf3b6e727e94 we could encode MXF files containing a timecode track to MP4 with:

$ ffmpeg -i 0002PW.MXF -sn -dn -y test.mp4                                                                                                                                                                                                                                                          [13:43:43]
