Abstract
A sequence of video images can be represented using multiple related timelines by generating a first timeline identifying a decode order associated with a sequence of video images and a second timeline identifying a display order associated with the sequence of video images, wherein the sequence of video images is comprised of one or more samples. The first and second timelines can be correlated based on an offset, which represents a time period by which decoding precedes display. The sequence of video images can then be played in accordance with the correlated first and second timelines. Additionally, the decode order in the first timeline can differ from the display order in the second timeline. A revised offset between the first and second timelines can be determined after the sequence of video images has been edited and the first and second timelines can be correlated based on the revised offset.
