[FFmpeg-cvslog] mxfdec: Ignore the last entry in Avid's index table segments

[Tomas Härdin]

ffmpeg | branch: master | Tomas Härdin <tomas.hardin at codemill.se> | Thu Jan 26 13:21:30 2012 +0100| [e24167aae6c6ce2839537356077faac5602694bc] | committer: Diego Biurrun

mxfdec: Ignore the last entry in Avid's index table segments

The last entry is the total size of the essence container.
Previously a TemporalOffset error would be logged, even though
segments like these are expected.
