测试
bash
ffmpeg -i 1.wmv -y -qscale 0 -vcodec libx264 11.mp4
实时视频推拉流:
bash
流服务可自行使用nginx+rtmp模板部署,
拉流:
ffplay rtmp://{serverIP}/live/stream
推流
windows: ffmpeg -f dshow -i video="USB2.0_CAM1" -vcodec libx264 -f flv rtmp://{serverIP}/live/stream
windows使用命令ffmpeg.exe -list_devices true -f dshow -i dummy 来查看对应摄像头的名字
linux: ffmpeg -f v4l2 -i /dev/video0 -vcodec libx264 -f flv rtmp://{serverIP}/live/stream
linux则通过 /dev/videoN 来判断
