[Libav-user] av_interleaved_write_frame error in muxing packets

[Lalit Patil]

Dear All,
please help me on this topic.
i m  trying to stream a local mp4 file to wowza server usi ng remuxing.c


AVOutputFormat *ofmt = NULL;
    AVFormatContext *ifmt_ctx = NULL, *ofmt_ctx = NULL;
    AVPacket pkt;
    const char *out_filename;
    int ret, i;
    CString inputFile;
    m_editFileName.GetWindowTextW(inputFile);

    //Convert CString to std:: String and then const char*
    CT2CA pszConvertedAnsiString(inputFile);
    std::string strStd(pszConvertedAnsiString);
    const char* in_filename(strStd.c_str());
    //Convert CString to std:: String and then const char* End

 but getting error in muxing apckets
