Привет, друзья. На самом деле я разрабатываю свой собственный видеоплеер, используя библиотеки VLCJ, я использую холст поверх JFrame и панель параметров с кнопками для воспроизведения, остановки и т. Д. В этот момент видеоплеер и все кнопки работают, но это настолько медленный, а частота кадров такая низкая, я думаю, что использование холста - не лучший способ воспроизведения видео, или, может быть, мой код не оптимизирован.
Основной класс:
package vlcvideo;
import java.io.File;
import javax.swing.JFileChooser;
public class VlcVideo {
static JFileChooser filex = new JFileChooser();
public static void main(String[] args)
{
String rutaVlc = "C:/vlc64/vlc";
String rutaVideo="/src/vlcVideo/c.mp4";
File ourFile;
//seleccionar la ruta de instalacion del vlc
/*filex.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);//selecciona solo directorios
filex.showSaveDialog(null);
ourFile=filex.getSelectedFile();
rutaVlc=ourFile.getAbsolutePath();*/
/*
filex.setFileSelectionMode(JFileChooser.FILES_ONLY);
filex.showSaveDialog(null);
ourFile=filex.getSelectedFile();
rutaVideo=ourFile.getAbsolutePath();*/
System.out.println(rutaVlc + "ruta DLL");
System.out.println(rutaVideo + " ruta video");
//new MediaPlayer(rutaVlc,rutaVideo).run();
//MediaPlayer mediaPlayer = new MediaPlayer(rutaVlc,rutaVideo);
prueba pb = new prueba(rutaVlc,rutaVideo);
// reproductor rp = new reproductor(rutaVlc,rutaVideo);
