After we made Zipcar, we though about expanding this system. Current Zipcar system is working with radio signals, but I wanted to make system that works on internet.
So, first work is to make video streaming service that works on internet.
Hardware: Raspberry pi, Raspberry pi camera(this is not webcam)
If you search on the internet, you will see many webpages that uses ‘mjpg‘ method. Actually I tried two methods
But both methods had too much latency. It was about 4~500 ms. Too much for real time control system.
So, tried gstreamer. I wanted to write how to use gstreamer. However there is already wonderful video in youtube.
After I used ‘gstreamer’, there was no latency.
Thanks to Brynlea Gibson. Her video helped me a lot. There would be no problem if you just follow this video.
Result: Better to use gstreamer rather then mjpg-streamer, if you need low latency system.
