            recorder.setVideoCodec(avcodec.AV_CODEC_ID_MPEG4);
            recorder.setFormat("mp4");
            recorder.setFrameRate(FRAME_RATE);
             recorder.setVideoBitrate((int) ((WIDTH * HEIGHT * FRAME_RATE)));
            Java2DFrameConverter java2DFrameConverter = new Java2DFrameConverter();
            recorder.start();
            for (int i = 0; i < images.size(); i++) {
                BufferedImage image = images.get(i);
                Frame frame = java2DFrameConverter.getFrame(image);
                recorder.record(frame, avutil.AV_PIX_FMT_ARGB);
            }
            recorder.stop();
            recorder.release();

Contributor guide

Research direction

Investigate alternative codecs (e.g., H.264) and hardware acceleration options. Optimize image format conversion and consider using FFmpegFrameRecorder with more efficient frame input methods.
