I was cruising thru the topics, but anyway can´t get it working.
I need to turn on this bash script:
export LD_LIBRARY_PATH=.
./mjpg_streamer -o "output_http.so -w ./www" -i "input_raspicam.so -x 640 -y 480 -fps 20 -ex night"
using python. I need a remote access to the Raspberry Pi, and writing this script to bash everytime I need to turn on the stream is just annoying. 
Any ideas how the code in python should look like?
Thank you guys.
