[Libav-user] PCMU - avcodec_open2 return -22 Unknow Error

[许凯军]

Hi!

When I try to open AV_CODEC_ID_PCM_MULAW by the code below:
Open_satus = -22.


    AVCodec* codec = avcodec_find_decoder(codec_id);
    if (!codec)
    {
        return -1;
    }

    m_ffmpeg_codec_context = avcodec_alloc_context3(codec);

    if (!m_ffmpeg_codec_context)
    {
        return -1;
    }

    int open_status = avcodec_open2(m_ffmpeg_codec_context, codec, NULL);
    if (open_status < 0)
    {
        CString formater;
        formater.Format("avcodec_open2 failed :%d\r\n", open_status);
        OutputDebugString(formater);
}



Did I make any mistakes?
