For a transcode task, these bookmarks are of interest:
MARK_CUT_END and MARK_CUT_START define the part of the video/recording,
which has to be transcoded.
MARK_UPDATED_CUT indicates that someone else has updated the cutlist /
markuptable.
In this case, the ongoing transcoding has to be stopped and terminated.
