A thermal camera is installed on a raspberry pi and running on a python program smoothly.
The live video/image will be posted on a new frame when running the python program.
More, the raspberry pi is collected in my home intranet with other devices, such as windows pc and smartphone.
All i want to go is watch the live video/image on the intranet by others device; or say browse the python program with web browser on other devices on intranet. I got some basic experience on programming but very poor about networking. And i try to make a simple "helloworld" webpage by flask.
do you think it's a simple question ? i just need to combine the following two python programs into one, and export in by flask?

And sorry again i can't delete or coorrect the original one. sorry.
