方法：

public static void pic2MovByFfmpeg(String mp4SavePath,String picturesPath, int width, int height) throws FFmpegFrameRecorder.Exception {
        //视频宽高最好是按照常见的视频的宽高  16：9  或者 9：16
        FFmpegFrameRecorder recorder = new FFmpegFrameRecorder(mp4SavePath, width, height);
        //设置视频编码层模式
        recorder.setVideoCodec(avcodec.AV_CODEC_ID_H264);
        //设置视频为1帧每秒
        recorder.setFrameRate(1);
        //设置视频图像数据格式
        recorder.setPixelFormat(avutil.AV_PIX_FMT_YUV420P);
        recorder.setFormat("mp4");
 
        File file = new File(picturesPath);
        File[] flist = file.listFiles();
        try {
            recorder.start();
            Java2DFrameConverter converter = new Java2DFrameConverter();
            //录制一个22秒的视频
            for (int i = 0; i < flist.length; i++) {
                BufferedImage read = ImageIO.read(flist[i]);
                recorder.record(converter.getFrame(read));

} } catch (Exception e) { e.printStackTrace(); } finally { //最后一定要结束并释放资源  recorder.stop(); recorder.release(); } }

测试：

@Test
    public void pic2movByFfmpeg() throws Exception {
        String picPath="C:\Users\Tyler\Postman\files";
        String videoPath="C:\Users\Tyler\Downloads\test.mp4";
        FileHelper.pic2MovByFfmpeg(videoPath,picPath,640,480);
    }
