vlcj - Ses Oynatıcı

Vlcj - Klavye Olaylarını İşleme bölümünü Ses Çalma özelliği ile güncelleyeceğimiz uygulamayı daha da geliştirelim. Video Oynatmaya benzer şekilde, bir Ses oynatmayı da kolay bir şekilde kontrol edebiliriz.

Bir Ses Oynatıcı Oluşturun

AudioPlayerComponent audioPlayerComponent = new AudioPlayerComponent();

Ses Yükle

Artık medyayı kullanarak, aşağıdaki sözdizimini kullanarak uygulamamıza kolayca bir ses yükleyebiliriz−

audioPlayerComponent.mediaPlayer().media().startPaused(path);

Ses Çal

Şimdi kontrolleri kullanarak, aşağıdaki sözdizimini kullanarak uygulamamızda bir ses klibini kolayca oynatabiliriz -

audioPlayerComponent.mediaPlayer().controls().play();

Misal

Eclipse'de Ortam Kurulumu bölümünde oluşturulan proje mediaPlayer'ı açın .

App.java'yı aşağıdaki kodla güncelleyin−

Dosyaya sağ tıklayarak uygulamayı çalıştırın ve Java Uygulaması olarak çalıştır'ı seçin. Başarılı bir başlangıçtan sonra, her şey yolundaysa, aşağıdaki sonucu göstermelidir -

Şimdi Ses Kontrollerinde oynat düğmesine basın ve bir klip oynamaya başlayacaktır. Duraklat düğmesine tıklamak sesi duraklatacaktır.
