資源簡介
本例子實(shí)現(xiàn)了推送本地視頻至流媒體服務(wù)器（以RTMP為例）。
是使用FFmpeg進(jìn)行直播功能
包含2個(gè)項(xiàng)目：
simplest_ffmpeg_streamer: 將本地視頻文件推送至流媒體服務(wù)器。
simplest_ffmpeg_receiver: 將流媒體數(shù)據(jù)保存成本地文件。
相應(yīng)的視頻文件為dakongtou.mp4 , 演示實(shí)驗(yàn)時(shí)分兩個(gè)窗口打開相應(yīng)項(xiàng)目文件，實(shí)現(xiàn)視頻數(shù)據(jù)實(shí)時(shí)收，發(fā)功能
