I'm not an expert on the start/stop thing (you can control the camera with ajax calls to the raspberry webserver, i assume), but how about using an iframe for display?

QUESTION

How to change WebKit macro to false from CSS or JS

Asked 2019-Feb-26 at 08:18

The new WebKit feature for loading large images asynchronously introduced in Safari Tech Preview 26 causes mjpg-streamer webcam based streams to flicker, the boolean property that defaults to true, largeImageAsyncDecodingEnabled, causes this issue. Link to the property definition

I am trying to find a way to set this property to false on the html page with CSS or JS. Is this even possible? Or is there another way to do it?

This is for OctoPrint running OctoPi for a 3D printer server. I found through trial and error, any image over 453x453 px is loaded asynchronously and causes the flicker to happen; it's akin to an annoying strobe light effect. I am using a resolution of 1280x720 for the webcam, and there is no issue before tech preview 26.

Thank you for the help!

You can't override the macro. But you may force the rest of the page to load after the image loaded.

By using CSS/JS? Why? Use plain HTML

There is a link rel preload markup exists. Read more here on W3C

The important parts are

The preload keyword on link elements provides a declarative fetch primitive that addresses the above use case of initiating an early fetch and separating fetching from resource execution. As such, preload keyword serves as a low-level primitive that enables applications to build custom resource loading and execution behaviors without hiding resources from the user agent and incurring delayed resource fetching penalties.

How to achieve that

QUESTION

Raspberry Pi MJPEG video stream - start application at reboot

Asked 2017-Jul-26 at 13:41

I am making a MJPEG video stream using Raspberry Pi with dedicated Pi Camera. For this I am using jpeg libraries and the following web application found on Github. The use is pretty straightforward, you just type cd mjpg-streamer/mjpg-streamer-experimental and then ./mjpg_streamer -o "output_http.so -w ./www" -i "input_raspicam.so". However, I would like to make it run on every reboot, so that the camera is "maintenance free".

I researched that I need to put the path and the executable file in the /etc/rc.local. Nevertheless, when I put the path (mjpg-streamer/mjpg-streamer-experimental/mjpg_streamer -o "output_http.so -w ./www" -i "input_raspicam.so") to this executable file, it did not work at all. I tried to run the stream as one command in the Terminal, it did not work either. I also tried to set up a variable PATH in .bashrc in order to access it from /etc/rc.local, but it also did not want to work.

I suspect it might have something to do with command ./mjpg_streamerneeding some input for it to work (-o "output_http.so -w ./www" -i "input_raspicam.so")

Do you have any idea how to start it with every reboot?

Thanks for your time and help

i have solved similar issue for my rpi and jpeg streamer as following.

create a shell script in /home/pi

touch /home/pi/mjpg-streamer.sh
edit that shell script and add this content

#!/bin/bash

cd /home/pi/mjpg-streamer/mjpg-streamer-experimental/

LD_LIBRARY_PATH=.

./mjpg_strea‌mer -o "output_http.so -w ./www" -i "input_raspicam.so"
make sure new shell script has execution rights
add that shell script to your /etc/rc.local
