流程介绍
首先
我们有一个RTMP流媒体服务器 这个是Nginx搭建的 使用的模块是nginx-rtmp使用ffmpeg进行推流 UDP协议或者RTMP协议
第一种方式推流 RTMP推流 直接推流至服务器
ffmpeg -re -i ./fly.mp4 -vcodec libx264 -acodec aac -f flv rtmp://localhost:1935/rtmplive/demo
- 第二种方式推流 UDP推流
ffmpeg -re -i best.mp4 -f h264 udp://127.0.0.1:1234
- 第二种方式推流 接收UDP流并转成RTMP推流至服务器
ffmpeg -i udp://127.0.0.1:1234 -vcodec copy -acodec aac -ar 44100 -strict -2 -ac 1 -f flv -s 1280x720 -q 10 rtmp://127.0.0.1:1935/rtmplive/demo2
- 使用ffmpeg命令进行拉流
# 直接是RTMP的流
ffplay rtmp://127.0.0.1:1935/rtmplive/demo
# UDP转RTMP的流
ffplay rtmp://127.0.0.1:1935/rtmplive/demo2
实际操作
UDP推流
ffmpeg -re -i best.mp4 -f h264 udp://127.0.0.1:1234
