从 Xuggler 中的帧获取视频

Question

我正在尝试使用 xuggler 将图像列表编码为视频。我有一系列缓冲图像。我正在使用以下代码。

public void encodeImage(BufferedImage originalImage, long timestamp) 
{

    //  BufferedImage worksWithXugglerBufferedImage = convertToType(originalImage, BufferedImage.TYPE_3BYTE_BGR);

    BufferedImage worksWithXugglerBufferedImage = convertToType(originalImage, BufferedImage.TYPE_3BYTE_BGR);

    IPacket packet = IPacket.make();
    IConverter converter = ConverterFactory.createConverter(worksWithXugglerBufferedImage, IPixelFormat.Type.YUV420P);

    IVideoPicture outFrame = converter.toPicture(worksWithXugglerBufferedImage, timestamp * 1000);
    outFrame.setQuality(0);


    outStreamCoder.encodeVideo(packet, outFrame, 0);

    if (packet.isComplete()) 
        outContainer.writePacket(packet); 

}

问题是它返回给我以下错误。

[WARN] [NioProcessor-1] com.xuggle.xuggler - Got error: picture is not of the same width as this Coder (../../../../../../../csrc/com/xuggle/xuggler/StreamCoder.cpp:1204)

错误是由于 outFrame 生成的，我已经检查了创建的框架的宽度和高度，并且图片是相同的。任何人都可以在这里帮助我或给我提示..

我使用了这里提供的来源。谢谢。

问题是先生，您一定错误地设置了输出流的高度和宽度。例如，

outStreamCoder.setHeight(height);
outStreamCoder.setWidth(width); 

您应该在此处正确输入视频高度，宽度也是如此。
