Pipe video stream from raspberry pi to local computer with ffplay
I use this to get a live video stream from my Raspberry Pi with Camera attached
Execute this on the Pi, where
TARGET_IP is my local computer where I will watch the stream, and
PORT is an arbitrary port number.
$ raspivid -t 999999 -o - | nc -u $TARGET_IP $PORT
Execute this on the local computer where you will watch the video stream
$ nc -ul $PORT | ffplay -
