屬性詳細資訊

len

屬性
public var len:Number

語言版本: ActionScript 3.0
執行階段版本: Flash Player 10, AIR 1.5, Flash Lite 4

streamName 中指定之串流的播放持續時間 (以秒為單位)。預設值為 -1,這表示 Flash Player 會播放即時串流直到不再有即時串流,或播放已錄製串流直到此串流結束。如果您將 0 傳遞至 len,Flash Player 會播放從已錄製串流開頭算起第 start 秒的單一影格 (假設 start 等於或大於 0)。

如果您將正數傳遞至 len,Flash Player 會在即時串流可用時播放長達 len 秒,或播放已錄製串流長達 len 秒 (若此串流長度不到 len 秒,在串流結束時即結束播放)。

如果您將 -1 以外的負數傳遞至 len,Flash Player 會將此值解譯為 -1。

相關 API 元素

offset

屬性 
public var offset:Number

語言版本: ActionScript 3.0
執行階段版本: Flash Player 10.1, AIR 2, Flash Lite 4

伺服器在不同位元傳輸速率串流之間切換,以便進行 Flash Media Server 動態串流處理的絕對串流時間點。當結合 NetStreamPlayTransitions.SWITCH 轉場模式呼叫 NetStream.play2() 時,就會使用 offset 屬性。共有兩種切換模式:快速切換與標準切換。offset 的預設值為 -1,即為快速切換模式。請撰寫 ActionScript 邏輯,以決定何時使用快速切換及何時使用標準切換。

快速切換

在快速切換模式中,Flash Media Server 會直接切換到新串流,而不會等待播放緩衝區中的資料。過去 offset 從舊串流中緩衝的任何資料都會被清除。快速切換比標準切換快,因為從舊串流緩衝的資料不必結束。

offset 的預設值為 -1,即為快速切換模式。當 offset 為 -1 時,切換會發生在 netstream.time + 3 之後的第一個可用的關鍵影格,大約比播放點晚 3 秒鐘。您也可以將 offset 屬性設定為大於 netstream.time 的任何值。例如,若要在播放點後快速切換 5 秒,請將 offset 屬性設定為 netstream.time + 5。如果 offset 的值小於 netstream.time,則會傳送 NetStream.Play.Failed 狀態事件。

注意:offset 屬性是絶對串流時間,不是與播放點相差的偏移值。例如,若要自播放點切換 5 秒,請將 offset 屬性設定為 netstream.time + 5,而非 5

標準切換

若要使用標準切換而非快速切換,請將 offset 設定為大於 netstream.time + netstream.bufferLength 的值。

當用戶端具有高緩衝區位元傳輸速率,並且由於頻寬中斷 (不是 CPU 問題或丟棄影格的因素) 而想要切換為較低的頻寬時,請使用標準切換。用戶端可以隨意結束較高的位元傳輸速率,並在緩衝結尾時切換到較低的位元傳輸速率 (就如同在標準切換般)。

如需詳細資訊,請參閱 Adobe Flash Media Server Developer's Guide 中的「在串流之間快速切換」。

相關 API 元素

oldStreamName

屬性 
public var oldStreamName:String

語言版本: ActionScript 3.0
執行階段版本: Flash Player 10, AIR 1.5, Flash Lite 4

舊串流或從中轉場之串流的名稱。當 NetStream.play2() 只用於播放串流 (未執行轉場) 時,這個屬性的值應該是 null 或 undefined。否則,請指定要從中轉場的串流。

相關 API 元素

start

屬性 
public var start:Number

語言版本: ActionScript 3.0
執行階段版本: Flash Player 10, AIR 1.5, Flash Lite 4

streamName 的開始時間,以秒為單位。有效值為 -2、-1 和 0。

start 的預設值為 -2,這表示 Flash Player 會先嘗試播放 streamName 中指定的即時串流。如果找不到該名稱的即時串流,Flash Player 就會播放 streamName 中指定的已錄製串流。如果找不到即時串流和已錄製串流,Flash Player 會開啟一個名為 streamName 的即時串流,即使其中沒有發佈內容。一旦有人開始在該串流上發佈,Flash Player 即開始加以播放。

如果您將 -1 傳遞至 start,Flash Player 只會播放 streamName 中指定的即時串流。若找不到該即時串流,而 len 設為 -1,Flash Player 將無限期等待;如果 len 設為其它的值,Flash Player 便會等待 len 秒,然後再開始播放於播放清單中的下一個項目。

如果您將 0 或正數傳遞至 start,Flash Player 只會播放名為 streamName 的已錄製串流,從串流開頭算起第 start 秒開始播放。若找不到已錄製串流,Flash Player 將立即開始播放於播放清單中的下一個項目。

如果您將 -1 或 -2 以外的負數傳遞至 start,Flash Player 會將此值解譯為 -2。
