Abstract
File format concepts for video coding are described. Embodiments allow for an efficient extraction of sub-streams from a video file. Further embodiments allow for a flexible switching between sub-streams of a video file. Further embodiments allow for a flexible handling of decoder initializations.
Claims21
1-21. (canceled)
File parser configured to:
- derive from a file switching information for a set of tracks, the switching information indicating samples of a first track of the set of tracks at which switching from a second track of the set of tracks is allowed provided that one or more preceding samples in the second track are available to a video decoder fed by the file parser from the file.
Non-transitory digital storage medium having stored thereon a file of a video, the file comprising:
- a set of tracks;
- and
- switching information for the set of tracks, the switching information indicating samples of a first track of the set of tracks at which switching from a second track of the set of tracks is allowed provided that one or more preceding samples in the second track are available to a video decoder fed from the file.
File generator configured to:
- provide a file with information for a set of tracks, the switching information indicating samples of a first track of the set of tracks at which switching from a second track of the set of tracks is allowed provided that one or more preceding samples in the second track are available to a video decoder fed from the file.
Method for processing a file, comprising:
- derive from the file switching information for a set of tracks, the switching information indicating samples of a first track of the set of tracks at which switching from a second track of the set of tracks is allowed provided that one or more preceding samples in the second track are available to a video decoder to which the file is provided.
Method for generating a file, comprising:
- provide the file with information for a set of tracks, the switching information indicating samples of a first track of the set of tracks at which switching from a second track of the set of tracks is allowed provided that one or more preceding samples in the second track are available to a video decoder fed from the file.
