这是一个使用jxcapture API录制音频和视频的程序。运行时出错。有人可以帮我解决这个问题。
import com.teamdev.jxcapture.Codec;

import java.io.File;
import java.util.List;
public class CaptureVideoFromWebCameraWithAudio {
public static void main(String[] args) throws Exception {
VideoCapture videoCapture = VideoCapture.create(VideoFormat.MP4);
List<VideoSource> availableVideoSources = VideoSource.getAvailable();
System.out.println("availableVideoSources = " + availableVideoSources);
if (availableVideoSources.isEmpty()) {
throw new IllegalStateException("No external video sources available");
}
VideoSource webCamera = availableVideoSources.get(0);
System.out.println("webCamera = " + webCamera);
videoCapture.setVideoSource(webCamera);
List<Codec> videoCodecs = videoCapture.getVideoCodecs();
Codec videoCodec = videoCodecs.get(2);
System.out.println("videoCodec = " + videoCodec);
EncodingParameters encodingParameters = new EncodingParameters(new File("WebCamera.MP4"));
encodingParameters.setBitrate(500000);
encodingParameters.setFramerate(10);
encodingParameters.setKeyFrameInterval(1);
encodingParameters.setCodec(videoCodec);
System.out.println("Available audio recording sources:");
List<AudioSource> audioSources = AudioSource.getAvailable();
for (AudioSource audioSource : audioSources) {
System.out.println("audioSource = " + audioSource);
}
if (audioSources.isEmpty()) {
System.err.println("No audio sources available");
} else {
AudioSource audioSource = audioSources.get(0);
System.out.println("Selected audio source = " + audioSource);
videoCapture.setAudioSource(audioSource);
List<AudioCodec> audioCodecs = videoCapture.getAudioCodecs();
if (audioSources.isEmpty()) {
System.err.println("No audio codecs available");
} else {
System.out.println("Available audio codecs:");
for (AudioCodec audioCodec : audioCodecs) {
System.out.println("audioCodec = " + audioCodec);
}
// Enable and configure audio encoding
AudioEncodingParameters audioEncoding = new AudioEncodingParameters();
AudioCodec audioCodec = audioCodecs.get(0);
System.out.println("Selected audio codec = " + audioCodec);
audioEncoding.setCodec(audioCodec);
encodingParameters.setAudioEncoding(audioEncoding);
}
}
System.out.println("encodingParameters = " + encodingParameters);
videoCapture.start(encodingParameters);
System.out.println("Recording started. Press 'Enter' to pause.");
System.in.read();
videoCapture.pause();
System.out.println("Recording started. Press 'Enter' to resume.");
System.in.read();
videoCapture.start();
System.out.println("Recording started. Press 'Enter' to stop.");
System.in.read();
videoCapture.stop();
System.out.println("Done.");
}
}
错误
Run:

虽然您很久以前就提出过这个问题,但请尝试将此maven依赖项添加到您的项目中:
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
<version>1.7.25</version>
</dependency>
如果您不使用maven,请从此处获取jar:https://www.slf4j.org/download.html
