gopro | : camera : GoPro Hero 4 - Python API | Camera library

i want to do image processing on a GoPro Hero4 Black livestream using OpenCV in C++. The firmware version is 5.0.

With python it successfully works. When i implement it the same (!) way in C++ status 31 and 32 switch to 1 when opening the VideoCapture, so the livestream is started and the client is connected. However, a following cap.isOpen() returns false. I need to add that the cap.open(...) command lets the program stop for some seconds which is unplausible.

The code in python

My goal is to get the one product object back depending on the product id i marked in green (out of the whole products array in my mongo DB)

My Backend entry looks as follows:

I am running a python script on a raspberry-pi.

Essentially, I would like a camera to take a picture every 5 seconds, but only if I have set a boolean to true, which gets toggled on a physical button.

initially I set it to true, and then in my while(true) loop, I want to check to see if the variable is set to true, and if so, start taking pictures every 5 seconds. The issue is if I use something like time time.sleep(5), it essentially freezes everything, including the check. Combine that with the fact that I am using debouncing for the button, it then becomes impossible for me to actually toggle the script since I would have to press it exactly after the 5s wait time, right for the value check... I've been searching around and I think the likely solution would have to include threading, but I can't wrap my head around it. One kind of workaround I thought of would be to look at the system time and if the seconds is a multiple of 5, then take picture (all within the main loop). This seems a bit sketchy.

Script below:

I have a video containing several streams. A few data and one video.

I need to extract the video stream, change the frame rate, embed it back in the video (or combine all stream back to an output file)

If needed, this is the list of existing streams:

I only need stream 0 and 5 (both video streams) Converted to 2 FPS. And stream 3 which is gpmd, which some irrelevant data format that I need to keep.

I have a SQLite table:

I want to create a directory structure table as described in this question where:

Directory = "Primary Key" id field, typically an integer
Directory_Parent = "Foreign Key" id field, which points to the id of another Directory in the same table
Value = string containing the directory/folder name

Given Tree/Fruit/Apples/

I have a SQLite table:

I am trying to make a slider for a list of products and I have placed a button on each side of the slider to slide the products. The problem I am facing is that it works fine when I press exactly at the buttons but when I press anywhere around it, it throws the error Uncaught TypeError: Cannot read property 'style' of null.

In this XML I am trying to find all time elements. (for example 2020-12-10T19:45:20.370Z)
