ffmepg 为什么错误：无法写入核心转储

如何解决ffmepg 为什么错误：无法写入核心转储

我想实现一项功能，允许我将 RTSP 流另存为文件，使用 javacv 实现一个演示，但是有一个错误。我调试演示，执行'recorder.record(frame);'错误，“ulimit -c unlimited”没用，程序还是报错。查看源代码确实注意到了问题的原理。请帮帮我。

        File outFile = new File(filePath);
        FFmpegFrameGrabber grabber = new FFmpegFrameGrabber(streamUrl);
        if (!outFile.getParentFile().exists()) {
            outFile.getParentFile().mkdirs();
        }
        FFmpegFrameRecorder recorder = new FFmpegFrameRecorder(filePath,1080,1440,1);
        recorder.setVideoCodec(avcodec.AV_CODEC_ID_H265);
        recorder.setFormat("flv");

        try {
