我正在使用gstreamer庫進行Java項目,需要能夠從網絡攝像頭捕獲圖像。如何從網絡攝像頭捕獲圖像WHILST也已經使用Java Gstreamer從網絡攝像頭進行流式傳輸?
我已經有顯示攝像頭流的代碼,我只是無法弄清楚如何在按下按鈕旁邊的按鈕來捕捉圖像。
我已經搜索了互聯網,但只能找到顯示流或捕獲圖像的代碼片段,但都沒有說明兩個...我試圖合併這些代碼段,但沒有'我也爲我工作。
我需要做些什麼才能使其發揮作用?
public class WebcamPanel extends JPanel {
private static Pipeline pipe;
public WebcamPanel(){
String[] args = {};
args = Gst.init("Webcam", args);
pipe = new Pipeline("pipeline");
final Element videosrc = ElementFactory.make("dshowvideosrc", "source");
final Element videofilter = ElementFactory.make("capsfilter", "flt");
videofilter.setCaps(Caps.fromString("video/x-raw-yuv, width=320, height=240"));
setLayout(new GridBagLayout());
final GridBagConstraints c = new GridBagConstraints();
JButton takePic = new JButton();
takePic.setPreferredSize(new Dimension(50,50));
c.gridx = 0;
c.insets = new Insets(0,10,0,0);
add(takePic,c);
c.gridx = 2;
c.gridwidth = GridBagConstraints.REMAINDER;
c.insets = new Insets(0,40,0,0);
SwingUtilities.invokeLater(new Runnable() {
public void run() {
VideoComponent videoComponent = new VideoComponent();
Element videosink = videoComponent.getElement();
// This gives 2nd window with stream from webcam
// Element videosink = ElementFactory.make("xvimagesink", "sink");
pipe.addMany(videosrc, videofilter, videosink);
Element.linkMany(videosrc, videofilter, videosink);
videoComponent.setPreferredSize(new Dimension(320, 240));
add(videoComponent,c);
videoComponent.setVisible(true);
// Start the pipeline processing
pipe.setState(State.PLAYING);
}
});
}
}
