Hi! I'm using such code for initialization:<br><br>    avcodec_register_all();<br>    av_register_all();<br>    avformat_network_init();<br><br>    const char *filename="rtp://<a href="http://192.168.0.101:10202">192.168.0.101:10202</a>";<br>
    <br>    AVOutputFormat *formatRTP = av_guess_format("rtp", filename, NULL);<br>    pFormatRTP = avformat_alloc_context();<br>    pFormatRTP->oformat = formatRTP;<br>    <br>    video_st = av_new_stream(pFormatRTP, AVMEDIA_TYPE_VIDEO);<br>
    avcodec_get_context_defaults3(video_st->codec, avcodec_find_encoder(CODEC_ID_H264));<br>    H264Context = video_st->codec;<br>    H264Context->codec_id = CODEC_ID_H264;<br>    H264Context->codec_type = AVMEDIA_TYPE_VIDEO;<br>
    H264Context->width = VideoWidth;<br>    H264Context->height = VideoHeight;<br>    H264Context->time_base.den = VideoFps;<br>    H264Context->time_base.num = 1;    <br>    H264Context->pix_fmt = PIX_FMT_YUV420P;<br>
    H264Context->flags |= CODEC_FLAG_GLOBAL_HEADER;<br>    <br>    if (avio_open(&pFormatRTP->pb, filename, 2) != 0) {<br>                return S_FALSE;<br>    }<br>    <br>    if(avformat_write_header(pFormatRTP, NULL)!=0)<br>
    {<br>            return S_FALSE;<br>    }    <br><br>But when I call av_sdp_create after that, it neither returns sprop-parameter-sets for sdp nor profile-level-id.<br>Can somebody help?
