안녕하세요..전 이번에 자바 프로젝트로 인터넷 동영상 메일을 구현하고 있는 학생입니다. 다시 말해서 일반 메일 서버와 같은 기능을 하면서 자신의 컴퓨터에 있는 동영상 화일을 데이터베이스가 있는 곳에 저장하여 수신자가 들어오면 그것을 애플릿으로 보여주는 것입니다.
그래서 SUN사에서 SimplePlayerApplet.java 라는 소스코드를 받아서 실행해 본 결과(물론 JMF2.0을 설치했구요)
동영상이 나오지 않습니다. 사운드는 나오는데요...
아무리 해봐도 결과는 같습니다.
(클래스 화일과 동영상 화일은 같은 디렉토리에 있습니다. html 코드드요. 그리고 애플릿 뷰어로나 IE에서 같은 결과 입니다)
컨트롤 바까지 나오는데 동영상이 나오지 않는 이유를 모르겠습니다. 알려주세요..
참고로 전 win98, IE 5.0을 쓰고 있구요...아래 제 컴에 있는 autoexec.bat 화일과 SimplePlayerApplet.java화일 넣겠습니다.
