Question

我正在尝试使用 Xuggle 库中包含的IConverter类进行一些图像处理，以将图像从IVideoPicture类型转换为BufferedImage类型但是我遇到了标题中的错误。

这是我的代码：

BufferedImage orgnlimage = new BufferedImage(Picture.getWidth(), Picture.getHeight(), BufferedImage.TYPE_3BYTE_BGR);
IConverter converter = ConverterFactory.createConverter(orgnlimage, IPixelFormat.Type.BGR24);
orgnlimage = converter.toImage(Picture); // Exception on this line

相关图片的尺寸 360x360 。

这是我得到的例外：

Exception in thread "main" java.awt.image.RasterFormatException: Data array too small (should be > 388799 )
    at sun.awt.image.ByteComponentRaster.verify(ByteComponentRaster.java:947)
    at sun.awt.image.ByteComponentRaster.<init>(ByteComponentRaster.java:201)

    at xuggler.Encrypt.main(Encrypt.java:53)
    at xuggler.DecodeAndSaveAudioVideo.main(DecodeAndSaveAudioVideo.java:141)

我的第二次尝试：

public IVideoPicture main(IVideoPicture Picture) throws NoSuchPaddingException, IllegalBlockSizeException, BadPaddingException, IOException
{ 
        int width = Picture.getWidth();
        int height = Picture.getHeight();
        long timestamp = Picture.getTimeStamp();

BufferedImage orgnlimage = videoPictureToImage(Picture);


        byte[] orgnlimagebytes =toByte(orgnlimage); 
        byte[] encryptedbytes = encrypt(orgnlimagebytes, "abc");
        //System.out.println(encryptedbytes.length);

        BufferedImage encryptedimage = toImage(encryptedbytes, width, height);   

        String desc = ConverterFactory.findDescriptor(encryptedimage);
       IConverter converter = ConverterFactory.createConverter(desc, Picture);


        IVideoPicture Pic = converter.toPicture(encryptedimage, timestamp);

        return Pic;

}

和堆栈跟踪：

Exception in thread "main" java.nio.BufferOverflowException
at java.nio.DirectByteBuffer.put(DirectByteBuffer.java:363)
at java.nio.ByteBuffer.put(ByteBuffer.java:859)
at com.xuggle.xuggler.video.BgrConverter.toPicture(BgrConverter.java:132)

at xuggler.DecodeAndSaveAudioVideo.main(DecodeAndSaveAudioVideo.java:141)

Answer 1

问题在于，由于某种原因，Xuggler BgrConverter.toImage()方法尝试在大小为byte的{{1}}数组周围创建一个栅格，这个数字短一个字节......它应该大小为388799（388800），用于BGR格式的图片。

我说file a bug report。

或者试试Humble Video，这似乎是Xuggler的继承者。

java.awt.image.RasterFormatException：数据数组太小（应该是＆gt; 388799）
