Marka
EmsgEvent
yeni
EmsgEvent(emsgData)
Parametre
emsgData
Nesne
Değer boş olamaz.
Özellikler
endTime
sabit
(sayı veya tanımsız)
Etkinliğin sona erdiği saat (sunum zamanında).
eventDuration
sabit
(sayı veya tanımsız)
Etkinliğin süresi (zaman ölçeği birimleri cinsinden).
id
sabit
(sayı veya tanımsız)
İletinin bu örneğini tanımlayan bir alan.
messageData
sabit
(null olmayan Uint8Array veya tanımsız)
schemeIdUri değeri ile işaret edilirse ID3 meta verilerini içerebilen mesajın gövdesi. schemeIdUri "https://aomedia.org/emsg/ID3" ve "https://developer.apple.com/streaming/emsg-id3" her zaman ID3 meta verilerini işaret eder.
presentationTimeDelta
sabit
(sayı veya tanımsız)
İçeren segmentin başlangıcına göre etkinliğin başladığı ofset (zaman ölçeği birimi cinsinden).
schemeIdUri
sabit
(dize veya tanımsız)
Mesaj şemasını tanımlar.
segmentData
sabit
(null olmayan Uint8Array veya tanımsız)
EMSG'yi içeren ham segment verilerinin tamamı. Bu alanın kullanımdan kaldırılması planlandı. Bu alan yerine sağlanan EMSG etkinlik verisi alanlarının kullanılması önerilir.
