I'm in the mid of my project where I'm trying to send the audio data over RTP
using ffmpeg in VC++.
but I'm unable to do that.:
setRTPOutputAddr("192.168.100.48");
setRTPOutputPort(9985);
av_register_all();
avformat_network_init();
formatCtx= avformat_alloc_context();
//av_dump_format(formatCtx,0,"rtp",1);
avio_open_dyn_buf(&ioctx);
avio_open(&formatCtx->pb, "rtp", AVIO_FLAG_WRITE);
//av_dump_format(formatCtx,0,"rtp",1);
formatCtx->pb = ioctx;
rtpCtx = avformat_alloc_context();
rtpCtx->oformat = av_guess_format("rtp",0,0);
AVStream *fakeVideo = 0;
fakeVideo = avformat_new_stream(rtpCtx,0);
avcodec_get_context_defaults3(fakeVideo->codec, NULL);
fakeVideo->codec->codec_id = AV_CODEC_ID_MPEG2TS;
rtpCtx->audio_codec_id = AV_CODEC_ID_NONE;
rtpCtx->video_codec_id = AV_CODEC_ID_MPEG2TS;
// avformat_write_header(rtpCtx,0);
char *url = new char[1024];
sprintf(url,"rtp://%s:%d",rtpOutputAddr,rtpOutputPort);
printf("will output to url:%s\n",url);
avio_open(&rtpCtx->pb,url,AVIO_FLAG_WRITE);
avformat_write_header(rtpCtx, NULL);
delete url;
if (avio_open(&formatCtx->pb, "rtp", AVIO_FLAG_WRITE) < 0)
{
fprintf(stderr, "Could not open '%s'\n",
formatCtx->filename);
return -1;
}
else
{
printf("succeed \n");
}
avformat_write_header(formatCtx, NULL);
Getting error here
Do any one having any idea why my program crashes here.
Thanks!
