錄製並顯示視頻JMF

我想從網絡攝像機錄製視頻並查看我在屏幕上錄製的內容。單獨地，我可以在需要網絡攝像頭的屏幕上看到它，或者錄製視頻，但不能同時看到它。當我錄製時，jpanel不會更新。它根本沒有報告錯誤。我該如何解決這個問題？非常感謝你。對不起我的英語不好。錄製並顯示視頻JMF

當我寫player.start（）;在processor = Manager.createRealizedProcessor（processorModel）之前;視頻記錄，但jPanel不會重新繪製，它始終是白色的。當我寫player.start（）; after processor = Manager.createRealizedProcessor（processorModel）;我看到了什麼記錄網絡攝像頭（jPanel repait），但是當我打開avi文件時，它是空的。 Plese幫助我任何人。我做錯了什麼？ – user2366175

嘗試使用jmapps jmstudio源代碼，在那裏有很好的代碼。它關於數據接收器和文件類型描述符。

理念：從通過捕捉設備源的記錄，你需要一個數據接收器那裏，然後在系統，存儲裝載到一個文件並加載從文件的球員。

如果您沒有從播放器中的文件中讀取它，它在JMF中不起作用。已經在線14.5年，JMF直播視頻沒有問題。
