Metadati multimediali comuni utilizzati come parte di MediaInformation o per descrivere una sezione multimediale come parte dei metadati del container.
L'elemento della coda che include questa sezione multimediale.
Pertinente solo se utilizzato nelle sezioni del contenitore e sono presenti più elementi multimediali per il contenitore.
sectionDuration
(numero o non definito)
La durata della sezione multimediale in secondi. Necessario solo se i metadati descrivono una sezione del file multimediale con un valore di durata diverso.
sectionStartAbsoluteTime
(numero o non definito)
Un modo alternativo per indicare l'ora di inizio della sezione per i contenuti multimediali dal vivo.
Fornisce l'ora di inizio in secondi.
sectionStartTimeInContainer
(numero o non definito)
Lo scarto in secondi relativo all'ora di inizio della sezione multimediale all'interno del contenitore.
Se non viene specificato, si presume che sia lo stesso dell'offset nel media.
sectionStartTimeInMedia
(numero o non definito)
L'ora di inizio della sezione multimediale all'interno del file multimediale in secondi.
Questo valore può essere negativo se una sezione è iniziata nel file precedente.
