My problem is that I can’t view the uv4l video stream from the picamera in my PC’s web browser.
My setup is: Raspberry Pi 3 - running Jessie - wireless connection to router. PC - running Windows 10 - Chrome browser - wired connection to router.
I wanted to add a camera to the front of a MonkMakes robot vehicle (controlled by the headless RPi) which would have minimum latency when streamed. According to the literature the installation of uv4l would achieve this.
I installed uv4l using the guide at http://www.linux-projects.org/uv4l/installation/ This appeared to go ok. The guide then says that the resulting stream can be viewed in the PC browser simply by entering http://[RPi ipaddress]:8080/ I have tried entering this url in the PC browser (with or without the port number) but all I get is that ‘Site could not be reached’ or ‘refused to connect’
I can ping from the RPi to PC and the PC to RPI. I can connect to the router admin page from both the PC & RPi using the router's ipaddress. I also successfully use VNC to connect from the PC to the headless RPI as well as using WinSCP to transfer files between the two.
Could anybody please explain in easy terms what I am doing wrong? As I am a NOOBy I feel that I have probably overlooked something fairly simple. Many thanks in anticipation.
Info requested by goldilocks: After installing
lsof and entering
sudo lsof -i tcp:8080 resulted in no output.
I also entered
sudo lsof -i tcp:1-1024 to check that
lsof was installed correctly. This resulted in:
