Android：使用LAN下載播放mp4視頻文件可能嗎？

Question

我是一名Android開發新手，遇到這個問題我的客戶希望從他的攝像頭存儲流視頻文件到他的android手機只使用局域網連接..這可能嗎？現在我唯一能做的就是從手機存儲器中播放視頻並傳輸http或RTSP流視頻，但是可以在通過LAN發送視頻文件的同時流式傳輸視頻文件嗎？謝謝。

@ Androider-I對不予評論表示歉意，因爲我無法反正這是我現在的代碼，任何形式的幫助將不勝感激。 編輯：

而在它之後崩潰客戶端我發送，不確定是否s是一個錯誤，因爲我的服務器有問題....

@Androider -Sorry for late update，這是我的結果代碼，我現在能夠通過視頻文件，並通過位控制它，但問題是我的數據總是被損壞，因爲丟失了一個字節或類似的東西，現在我該如何傳輸它？我無法播放該文件，因爲它不完整？如果是這種情況，那麼字節控制的目的是什麼？我希望你能再次幫助我thx。

其實這是。您需要在應用程序中構建自己的套接字服務器並從中播放視頻。然後你將有控制字節輸入流和保存dowloaded部分文件，而同一部分將去mediaplayer
