녹화와 사진캡쳐 기능을 넣었다.
물론 내가 한건 아니다.
Xuggler Library가 다했다. 라이브러리가 근데 너무크다 38MB
Xuggle-Xuggler 5.4.jar 파일인데 Xuggler란 영상을 디코딩, 인코딩 하는 라이브러리라 한다.
아무튼 내가 만든것!
만든것이라 보기보다는 라이브러리 사용한것! 이라는게 맞겠지만.. ㅎㅎ

필요한 라이브러리중 가장 대표적인게 xuggle-xuggler-5.4.jar 파일인데
https://mvnrepository.com/artifact/xuggle/xuggle-xuggler/5.4
위의 링크 들어가서 jar 누르면 파일이 다운된다. 다운받아서 사용하면 됨
