我已经看到了一些有关使用此API(网络摄像头捕获)的视频捕获的代码,但仅限于视频图像捕获,即无音频的视频(例如,下面记录的Encoder.java示例文件)。我正在开始一个需要此功能的项目,我认为此API非常轻巧且有用。有人可以通过在此类中添加代码(或显示一个新代码)来帮助我,以便它可以同时捕获视频和音频并写入同一文件吗?
public class Encoder {
public static void main(String[] args) throws Throwable {
File file = new File("output.ts");
IMediaWriter writer = ToolFactory.makeWriter(file.getName());
Dimension size = WebcamResolution.QVGA.getSize();
writer.addVideoStream(0, 0, ICodec.ID.CODEC_ID_H264, size.width, size.height);
Webcam webcam = Webcam.getDefault();
webcam.setViewSize(size);
webcam.open(true);
long start = System.currentTimeMillis();
for (int i = 0; i < 50; i++) {
System.out.println("Capture frame " + i);
BufferedImage image = ConverterFactory.convertToType(webcam.getImage(), BufferedImage.TYPE_3BYTE_BGR);
IConverter converter = ConverterFactory.createConverter(image, IPixelFormat.Type.YUV420P);
IVideoPicture frame = converter.toPicture(image, (System.currentTimeMillis() - start) * 1000);
frame.setKeyFrame(i == 0);
frame.setQuality(0);
writer.encodeVideo(0, frame);
// 10 FPS
Thread.sleep(100);
}
writer.close();
System.out.println("Video recorded in file: " + file.getAbsolutePath());
}
}
