Raspberry Pi 3 as Web Server: Camera Streaming
@kreggly Thank you for all your help with streaming the Pi Camera! I looked on YouTube to see if there were any videos about using the Pi Camera and streaming it onto the web server, and I found this video by Pi My Life Up:
The first section of the video is about using a USB camera. I completed the instructions in that section and went on to the second part, which was about using RasPi Camera. I got to the final command at 4:38 where Pi My Life Up tells you how to test it using the command ./motion -n -c motion-mmalcam.conf. For me, I got this error:
./motion: error while loading shared libraries: libavformat.so.53: cannot open s hared object file: No such file or directory
File Properties/General, as seen in Cayenne Remote Acess
File Properties/Permissions, as seen in Cayenne Remote Acess
I entered the command sudo chmod +x motion to make it executable (just in case) and then tried the original command. When that did not work, I tried using sudo:
pi@raspberrypi:~/mmal $ sudo chmod +x motion
pi@raspberrypi:~/mmal $ ./motion -n -c motion-mmalcam.conf
./motion: error while loading shared libraries: libavformat.so.53: cannot open s hared object file: No such file or directory
pi@raspberrypi:~/mmal $ sudo ./motion -n -c motion-mmalcam.conf
./motion: error while loading shared libraries: libavformat.so.53: cannot open shared object file: No such file or directory
Since nothing else worked, I gave up (for now! 
), so I uploaded it to community.mydevices.com and here I am now. Thank you for all your help!
P.S. Found a Raspberry Pi forum thread that may be of some help:
