1. A method, comprising:
generating a bitstream defining a presentation, the presentation comprising an omnidirectional visual media content and a first visual media component and a second visual media component;
indicating in the bitstream a first presentation timeline associated with the first visual media component;
indicating in the bitstream a second presentation timeline associated with the second visual media component;
indicating in the bitstream a switching mode with respect to the first presentation timeline associated with the first visual media component, or with respect to the second presentation timeline associated with the second visual media component, the switching mode being indicated dependent on a viewpoint of a user viewing the presentation;
wherein the switching mode provides an indication of switching to the first visual media component or to the second visual media component, the first visual media component corresponding to content captured from at least a first omnidirectional camera in a first location, and the second visual media component corresponding to content captured from at least a second omnidirectional camera in a second location; and
indicating in the bitstream a time offset variable that specifies a time offset to be used when switching to a viewpoint identifier.
