Hi kalileo,
Thanks for the reply, yes I just tried this - i.e. looking at following
code:
if(avformat_find_stream_info(this->pFormatCtx, NULL)<0)
return -1; // Couldn't find stream information
// Dump information about file onto standard error
av_dump_format(this->pFormatCtx, 0, this->finalInputName.c_str(), 0);
At time of opening up decoder for live udp stream (like:
udp://localhost:8765/a.h264) is still giving me bit_rate '0'.
