爲活動源過濾器創建媒體樣本時間戳？

Question

我試圖寫一個UDP流媒體應用程序與directshow打算在局域網環境中工作。直到客戶在尋找時纔開始遇到凍結問題，情況變得很好。

這裏是我做過什麼：

服務器

客戶

在服務器端，我有兩個變換濾波器，一個對於視頻和一個音頻。在這兩個過濾器中，每個過濾器創建一個讀取MediaSamples並執行多播而不修改時間戳/標記的線程。同時，視頻轉換過濾器只是將媒體樣本傳遞給解碼器。音頻轉換過濾器也會這樣做。

在客戶端。實時源過濾器只是從UDP端口讀取視頻和音頻MediaSamples。在這裏，我執行一些簡單的時間戳的計算是：

MediaSample開始時間=當前流時間+ 40毫秒

的視頻流會在局域網環境就好了。但是，當我找到時，我發現客戶端會凍結一會兒。當我檢查渲染器時，它會顯示很多幀被丟棄。我猜測時間戳導致幀丟失。

我也注意到，無論何時執行搜尋，初始幀通常都有負面郵票。如果我不發送這些幀到客戶端，客戶端不會凍結。但有些框架會被打破。我猜這是因爲這些消極的框架是導致尋求位置的關鍵幀。如果他們錯過了，圖像將被打破。

做一些研究之後，我嘗試這樣的做法：

1. 設置第一個樣本的時間戳當前流時間。

   T1 =流時間。

2. 使用此第一個樣本的時間戳作爲基準。

   基地= T1

3. 每個樣品後的計算公式爲

   Tn的=流時間+ Tn的 - 基本

其中也沒有工作。我猜這是因爲服務器和客戶端的時鐘不同步。但是，我認爲它可能會起作用，因爲在服務器端的每次查找後，時間戳都會從0開始。

我想弄清楚下一步該做什麼。 我真的很感激，如果有人可以給我一些建議。

羅馬，感謝您的幫助。我試圖與在http://social.msdn.microsoft.com/Forums/windowsdesktop/en-US/c1c762a0-af92-4987-b084-f0d194766999/is-a-video-sample-with-negative-timestamp-a-preroll-sample

1. 客戶提及的方法變基時間戳通過檢查IMediaSample :: IsDiscontinuity
2. 如果發生不連續檢測不連續性，設置基線（B）所接收到的時間戳
3. 然後每時間戳被計算爲

TS - 接收時間戳TC - 計算時間戳

TC = Current Stream Time + TS - B + 40ms 

，我用CRefTime和StreamTime（）

獲取當前流時間作出上述變動，當我開始流之後，客戶端的視頻移動緩慢一段時間並最終凍結。在停止服務器發送數據後，客戶端的屏幕再次活動約半秒鐘。

我在這裏做錯了什麼？是關於時鐘頻率？

繼羅馬的建議下，我能夠通過，讓我檢查從SourceFilter的到來時間戳的SourceFilter後加入具有通濾波器來找到我的時間戳錯誤視頻輸出引腳。

但是，現在我在尋求時遇到了另一個問題。在客戶端，儘管所有幀都能正確顯示，但在開始更新新幀之前，它會遭受巨大的延遲。

我檢查了這些框架，他們是預導幀，導致我的查找位置的幀。我通過將媒體樣本中的預卷標誌設置爲false並讓它播放來確認它。看起來，圖表正在客戶端以正常速率處理這些預卷幀，但在服務器端，這些預卷幀處理更快。

有沒有辦法避開這個延遲或者它只是我必須處理的事情？

這些是我通過過濾器捕獲的樣本。

尋求包括暫停和重新啓動流媒體：你有時間上的不連續衝壓。您必須在發送端自動重新分配時間戳以恢復連續性，或者在客戶端檢測此時間戳並重新設置時間戳。或者，另一種選擇是，客戶端會刷新隊列並繼續新鮮。
