树莓派视频推流

raspivid -fl -t 0 -w 960 -h 720 -b 1200000 -fps 15 -pf high -o - |ffmpeg -f h264 -i - -c copy -an -f flv -y rtmp://localhost/live/t1

ffmpeg 拉rtsp 推rtp

ffmpeg -re -i  "rtsp://admin:shhk@123@192.168.8.100:554"   -fflags nobuffer  -vcodec copy -f rtp_mpegts rtp://127.0.0.1:1234

阿里云管道端口转发:
rm -rf /tmp/fifo; mkfifo /tmp/fifo;nc -ll -p 9900 < /tmp/fifo | nc -ll -p 9901 > /tmp/fifo
raspivid -fl -t 0 -w 960 -h 720 -b 1200000 -fps 15 -pf high -o - |nc s2.icode.ml 9900
