Could not initialize class org.bytedeco.javacpp.avutil Linux x86_64

[Wangxy013]

Hello, I tried to use javaCV to call ffmpeg for audio transcoding, and an error was reported when initializing FFmpegFrameGrabber: Could not initialize class org.bytedeco.javacpp.avutil. It is normal for me on the windows10 platform, I have this error when I push my code to the linux server I understand that this is a relatively common problem, and the answer is generally like https://github.com/bytedeco/javacv/issues/1206#issuecomment-493274635> "You'll need to put all the JAR files in your class path for this to work". I have repeatedly checked my dependencies and tried to adjust the version, but it has not been resolved.

public class AudioConvert {
	public static Map<String, Object> convert(byte[] inputBytes, int audioCodec, int sampleRate, int audioBitrate,
	                                          int audioChannels) {
		Map<String, Object> resultMap = new HashMap<>();
		byte[] outputBytes = null;
		Frame audioSamples = null;
		FFmpegFrameRecorder recorder = null;
		ByteArrayInputStream inputStream = null;
		String fileFolderPath = "/abc";
		File fileFolder = new File(fileFolderPath);
		if (!fileFolder.exists() && !fileFolder.isDirectory()) {
			fileFolder.mkdirs();
		}
		String outputFile = fileFolderPath + RandomStringUtils.randomAlphanumeric(10);
		//ByteArrayOutputStream outputStream = null;
		inputStream = new ByteArrayInputStream(inputBytes);
		//outputStream = new ByteArrayOutputStream();
		FFmpegFrameGrabber grabber = new FFmpegFrameGrabber(inputStream);

		if (start(grabber)) {
			recorder = new FFmpegFrameRecorder(outputFile, audioChannels);
			recorder.setAudioOption("crf", "0");
			recorder.setAudioCodec(audioCodec);
			recorder.setAudioBitrate(audioBitrate);
			recorder.setAudioChannels(audioChannels);
			recorder.setSampleRate(sampleRate);
			recorder.setFormat("mp3");
			recorder.setAudioQuality(10);
			recorder.setAudioOption("aq", "10");
			if (start(recorder)) {
				try {
					while ((audioSamples = grabber.grab()) != null) {
						recorder.setTimestamp(grabber.getTimestamp());
						recorder.record(audioSamples);
					}

				} catch (org.bytedeco.javacv.FrameGrabber.Exception e1) {
					System.err.println("抓取失败");
				} catch (Exception e) {
					System.err.println("录制失败");
				}
				stop(grabber);
				stop(recorder);
			}
			try {
				outputBytes = Files.readAllBytes(new File(outputFile).toPath());
			} catch (IOException e) {
				e.printStackTrace();
			}
		}
		resultMap.put("outputBytes", outputBytes);
		resultMap.put("outputFilePath", outputFile);
		return resultMap;
	}

I tried to adjust the version of javaCV and ffmpeg, my maven dependency is:

The error I get on the linux_x86_64 platform is:

hope to get help, thanks~

NoClassDefFoundError means that some other class could not load. The cause of the error is going to be logged with that other exception, so please look for other errors in your logs, and that should tell you why it's failing.

Also, to get more information, make sure that the "org.bytedeco.javacpp.logger.debug" system property is set to "true" or that "org.bytedeco.javacpp.logger" is set to "slf4j" with your logger set to its debug level.

Please try again with JavaCV 1.5.6!
