1. A file parser for providing a video bitstream based on a set of tracks of a file signaling a coded video sequence, each of the set of tracks representing a sub-stream of the video sequence, wherein the file parser is configured to derive from descriptive data within the file a subset of tracks of the set of tracks complying with a predetermined operation point, forward the sub-streams of the subset of tracks in the video bitstream, wherein the file parser is configured to derive from the descriptive data within the file an operation point entity group syntax structure describing the predetermined operation point, the operation point entity group structure identifying the tracks of the subset of tracks which are associated with the predetermined operation point, and derive from the entity group syntax structure the subset of tracks, wherein the operation point entity group syntax is stored in the file on file level outside of the tracks.
