我使用Xuggler,我已經使用了視頻文件的絕對路徑,當我在Netbeans中運行時,它完美地工作,但是當我從jar文件啓動它時,視頻不出來..這裏的代碼從JAR文件運行程序時視頻不起作用
File file = new File("C:\\qssinfo\\video\\Wildlife.avi");
decodeAndPlayVideo.PlayVideo(file);
這是DecodeAndPlayVideo類的代碼,(我從xuggler得到它,我編輯了一小)

請你能幫助我,我得到一個月X的堆棧(
堆棧? 「堆棧一個月」是什麼意思?你的意思是「卡住」嗎?如果是這樣,那麼這與Java問題有什麼關係呢? –
另外這個:'@SuppressWarnings(「deprecation」)'讓我擔心只是一點點*! –
當您嘗試運行此操作時,是否看到任何錯誤消息? –
