Youtube不接受我用javacv从一个mp4和jpeg生成的mp3

Question

Youtube不接受使用javacv从mp4和jpeg生成的mp3

我使用youtube java api来上传这个文件，上传时也不会抛出任何异常。一个错误，我粘贴在下面发生时，只有当我去youtube网站。观看上传的视频或手工上传视频。

mp4文件的长度为00:59，大小为506 kb，所以我不认为这是一个问题。

这是代码：

public static void MergeMp3Mp4JavaCv(String path2ImageFile,String path2AudioFile, String path2OutputFile) throws IOException
    {

        IplImage ipl = cvLoadImage(path2ImageFile);
        int height = ipl.height();
        int width = ipl.width();
        if(height%2!=0) height = height+1;
        if(width%2!=0) width = width+1;

        OpenCVFrameConverter.ToIplImage grabberConverter = new OpenCVFrameConverter.ToIplImage();  
        FFmpegFrameRecorder recorder = new FFmpegFrameRecorder(path2OutputFile,width,height); 
        FrameGrabber audioFileGrabber = new FFmpegFrameGrabber(path2AudioFile);
        try 
        {  
            audioFileGrabber.start();

            recorder.setFrameRate(1);  
            recorder.setVideoBitrate(audioFileGrabber.getAudioBitrate());  
            recorder.setFormat("mp4");  
            recorder.setAudioChannels(1);
            recorder.start();  

            recorder.record(grabberConverter.convert(ipl));  
            Frame frame = null;
            while ((frame = audioFileGrabber.grabFrame())!=null) 
            {
                recorder.record(frame);
            }

            recorder.stop();  
            audioFileGrabber.stop();
         }  
         catch (org.bytedeco.javacv.FrameRecorder.Exception e){  
           e.printStackTrace();  
         }  
    }

Youtube说：

我查过https://support.google.com/youtube/answer/1722171?hl=en了

Audio codec: AAC-LC
Channels: Stereo or Stereo + 5.1
Sample rate 96khz or 48khz

Video codec: H.264
Progressive scan (no interlacing)
High Profile
2 consecutive B frames
Closed GOP. GOP of half the frame rate.
CABAC
Variable bitrate. No bitrate limit required, though we offer recommended bit rates below for reference
Chroma subsampling: 4:2:0

我试过了

recorder.setAudioCodec(avcodec.AV_CODEC_ID_H264 );
recorder.setAudioCodec(avcodec.AV_CODEC_ID_AAC);

也尝试过很多其他的视频编解码器，但是都没有用。

有人知道我做错了什么吗？

我终于让它像这样工作了

public static void MergeMp3AndJpegIntoMp4(String path2ImageFile,String path2AudioFile, String path2OutputFile) throws IOException
    {

        IplImage ipl = cvLoadImage(path2ImageFile);
        int height = ipl.height();
        int width = ipl.width();
        if(height%2!=0) height = height+1;
        if(width%2!=0) width = width+1;

        OpenCVFrameConverter.ToIplImage grabberConverter = new OpenCVFrameConverter.ToIplImage();  
        FFmpegFrameRecorder recorder = new FFmpegFrameRecorder(path2OutputFile,width,height); 
        FrameGrabber audioFileGrabber = new FFmpegFrameGrabber(path2AudioFile);
        try 
        {  
            audioFileGrabber.start();

            recorder.setVideoCodec(avcodec.AV_CODEC_ID_H264 );//AV_CODEC_ID_VORBIS
            recorder.setAudioCodec(avcodec.AV_CODEC_ID_AAC);//AV_CODEC_ID_MP3 //AV_CODEC_ID_AAC

            recorder.setFormat("mp4");  
            recorder.setAudioChannels(2);
            recorder.start();  

            Frame frame = null;
            while ((frame = audioFileGrabber.grabFrame())!=null) 
            {   recorder.record(grabberConverter.convert(ipl));  
                recorder.record(frame);
            }

            recorder.stop();  
            audioFileGrabber.stop();
         }  
         catch (org.bytedeco.javacv.FrameRecorder.Exception e){  
           e.printStackTrace();  
           throw e;
         }  

    }
