獲取錯誤在xcode中集成dropcam庫

我是iPhone應用程序開發的新手，我想通過我的應用程序在iPhone中進行實況流式傳輸。請建議我如何在iPhone/iPad上開發視頻流。目前，我對RTSP視頻在iPhone流整合dropcam庫，但LIVE555，DecoderWrapper，在我的項目的ffmpeg和libswscale庫的整合之後，我已經得到15錯誤：獲取錯誤在xcode中集成dropcam庫

請幫我解決這些錯誤或請告訴我如何在iPhone/iPad上工作視頻流。

選擇項目>構建階段>擴大編譯源代碼>按+>添加libDecoderWrapper.m

或者刪除庫，並重新將其添加到Xcode的同時確保「添加到目標」複選框被選中自動將所有內容添加到編譯源代碼階段，Xcode 4.3中存在一個錯誤，使得該複選框未被選中。

感謝您的回覆，但是當我選擇我的項目>構建階段>按+>然後我得到框架和libDropcam.a庫列表。所以如何添加libDecoderWrapper.m文件。請給我建議。 – rajeev 2012-03-02 05:42:15
