Answer 1

这是下面的解决方案；（Çözümüm aşağıdadır。）

// Gstreamer init - İlklendir
Gst.init(Version.BASELINE, "BasicPipeline");

// Create a named pipeline - sink isimli bir pipeline yarat.
pipeline = (Pipeline) Gst.parseLaunch("videotestsrc ! appsink name=sink");

// Create am appsink that refers to pipeline - sink'ten bir appSink nesnesi yarat
AppSink sink = (AppSink) pipeline.getElementByName("sink");

// Create GstVideoComponent object - gstVc objesi yarat.
GstVideoComponent vc = new GstVideoComponent(sink);
vc.setSize(600, 560);
vc.setVisible(true);

// main screen is a form screen that is public static and has a jform named panel_video  - vc'yi form'a ekle
mainScreen.panel_video.add(vc);

// play video - video'yu koştur.
pipeline.play();
