# Snippets

# Process a video on the server and play it on the client
## Server:
ffmpeg -i "a_video_file.mp4" -f avi pipe:1 | nc -l -p 1234
## Client
nc SERVERIP 1234 | ffplay -fs -i pipe:0

# Share your monitor
# If the server has ffmpeg:
## Server:
ffmpeg -f fbdev -i /dev/fb0 -f avi pipe:1 | nc -l -p 1234
## Client (viewer):
nc SERVERIP 1234 | ffplay -fs -i pipe:0
# If the server doesn't have ffmpeg:
## Server:
sudo cat /dev/fb0 | nc -l -p 1234
## Client (replace 1920x1080 with the server's resolution):
nc SERVERIP 1234 | ffplay -f rawvideo -vcodec rawvideo -pixel_format bgra -video_size 1920x1080 -i pipe:0
