The stream offset is used to calculate the presentation time of a metadata object when reading and later when playing, to calculate the current presentation time to decide whether to send the metadata to the output. Accordingly, the presentation time of a pending metadata that has been calculated with a given offset needs to be recalculated when the stream offset changes. #minor-release PiperOrigin-RevId: 472499943 (cherry picked from commit 5a1223777c4d4ee2faa4043be2079971e44093a9)
