The following is my code: run at windows 10 ，result is success。

S3Utils s3Utils = new S3Utils();
InputStream is = s3Utils.getInputStreamFromS3(bucketName, key);  // fetch video InputStream 
FFmpegFrameGrabber frameGrabber = new FFmpegFrameGrabber(is,1000000);
Frame captured_frame = null;
FFmpegFrameRecorder recorder = null;
try {
            FFmpegLogCallback.set();
            frameGrabber.setOption("rtsp_transport", "tcp");
            frameGrabber.start();
            frameGrabber.flush();

            recorder = new FFmpegFrameRecorder("demo.mp4", 720, 405, frameGrabber.getAudioChannels());
            recorder.setVideoCodec(avcodec.AV_CODEC_ID_H264);
            recorder.setFormat("mp4");
            recorder.setFrameRate(frameGrabber.getFrameRate());

            recorder.setVideoBitrate(640 * 1024); 
            recorder.setAudioBitrate(192000);
            recorder.setAudioOptions(frameGrabber.getAudioOptions());
            recorder.setAudioQuality(0);
            recorder.setSampleRate(44100);
            recorder.setAudioCodec(avcodec.AV_CODEC_ID_AAC);
            recorder.start();

           while (true) {
                try {
                    captured_frame = frameGrabber.grabFrame();

                    if (captured_frame == null) {
                       break;
                    }

                    recorder.record(captured_frame);
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
            recorder.stop();
            recorder.release();
            frameGrabber.stop();
            frameGrabber.release();
            recorder.close();
            frameGrabber.close();
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            s3Utils.shutdown();
        }

The following is pom dependency: `

org.bytedeco javacv 1.5.6 org.bytedeco ffmpeg-platform 4.4-1.5.6 pom

`

Please try again with JavaCV 1.5.7.

Using javacv 1.5.7, the same error occurs, and windos10 also reports an error. If the following parameter 1000000 is removed,

FFmpegFrameGrabber frameGrabber = new FFmpegFrameGrabber(is,1000000);

Then windows10 runs successfully. The conversion of small files on Linux will be successful, and the following errors will be reported for large files (such as 27g). The Linux memory is 16g

If sounds like you're trying to use a format that doesn't support streams well. Please try to use another format.

FFmpegFrameGrabber frameGrabber = new FFmpegFrameGrabber(is, 0); Set the parameter maximumsize to 0 and run successfully on both Linux and windows

saudet，Thanks for your answer
