Time is too short, there is no way to solve for a while, no way out, and planning a fight

Ffmpeg:
Av_register_all ();
Avformat_network_init ();
->
Avformat_open_input
->
Avformat_find_stream_info
->
Av_dump_format
->
FileDuration=AVFormatContext - & gt; Duration/1000.0/1000.0;

Can be used for audio and video files and the network flow,
