vlcj를 사용하여 여러 비디오 패널을 만들었습니다. 그때 내가 (동적되지 않음) 이러한 코드를 반복해야합니다 (8 개) 비디오 패널을 갖고 싶어VLCJ 여러 비디오 패널 만들기
factory0 = new MediaPlayerFactory();
mediaPlayer0 = factory0.newEmbeddedMediaPlayer();
mediaPlayer0.setVideoSurface(factory0.newVideoSurface(videoCanvas[0]));
mediaPlayer0.setPlaySubItems(true);
...
: 각 비디오 창을 위해 나는 코드를 추가해야합니다.
내 질문은 : 나는 MediaPlayerFactory 및 MediaPlayerFactory를 배열로 사용하여 코드를 단축 할 수 있으며이 코드는 Num_Video를 변경하여 동적으로 동작합니다.
완전한 코드는 다음과 같습니다. mainPanel에서 4 개의 비디오 패널을 제작 중입니다.
감사합니다. 나는이
EmbeddedMediaPlayer mediaPlayer[] = new EmbeddedMediaPlayer[Num_Video];
에 의해 다음 루프에서 달성 할 수 있어요
