Using this code

        AVCodec *pAVCodec= avcodec_find_encoder(CODEC_ID_MPEG4);
        if (!pAVCodec) qDebug() << "avcodec_find_encoder Error!!!";
        else {
            AVCodecContext *pAVCodecContext= avcodec_alloc_context(); {
                pAVCodecContext->pix_fmt= PIX_FMT_YUV420P;
                pAVCodecContext->width= Width;
                pAVCodecContext->height= Height;
                pAVCodecContext->time_base.den= 25;
                pAVCodecContext->time_base.num= 1;

                                    int OutSize= 
avcodec_encode_video(pAVCodecContext, pOutBuffer, BYTEPIC, pAVFrame);
                                    fwrite(pOutBuffer, 1, OutSize, FileOut);

With this code I can produce a mpg file that I can see it with mplayer but not 
with vlc. Vlc does not show a good error report, only this rows:

What can I do to adjust my code in order to produce a mpg file for vlc?
