Hi there, The "Download Beta image of Raspberry Pi Camera Stream" image returns a 404 error, Was this ever done?

Hi, Thanks for your code,

My camera is up side down, I wanted to flip the image using the flip = True but nothing... I tried also to change the value in np.flip(frame,-1) , np.flip(frame,1) .... but nothing....

Any solution to help ?

thanks

I followed this project with a rPi 3B+ and rPi camera module - everything worked great! When I set it up to run headless, it looks like the process starts, grabs one frame, then freezes. I'm not savvy enough to debug the main.py or camera.py files and understand/identify any issues.

How to save the video as an MP4 file at 1 hour intervals while establishing a video stream through flask?

No module named cv2. Open cv installed correctly

OSError: libmmal.so: cannot open shared object file: No such file or directory

this is a 3 year old project and looked like a good thing for the pi for a rookie to start with. however after following all steps and doing all install i got errors in 3 of 9 items.

sudo apt-get install libjasper-dev
sudo apt-get install libqtgui4
sudo apt-get install libqt4-test

is there any chance of a work around or even an update?..

hi I try to stream with different wifi connection but the page is not opening kindly do let me know how to access with different wifi connections too

How can i change the Port?

I think it's better to use cron to run main.py instead of doing so in /etc/profile. It looks like every time you log in more than once, it tries to run main.py and errors show up.
$sudo crontab -u root -e
@reboot python3 /home/pi/pi-camera-stream-flask/main.py

1. I would like to use raspivid --roi (region of interest) option.
2. the stream is to dark , is there a way to control the brightness?
   Thanks

Hi,

Due to changes on how raspberry pi handles its cameras modules this project is broken at the moment.
I was wondering if there any plans to update it for versions Bullseye 11 , and if not I would appreciate if you could tell me what version you were using when this was still working.
I also included bellow the error message I got when I tried to run this code on Bullseye 11 in case anyone has been having the same issue.
If anyone also has a solution I would greatly appreciate it.

I am having issues with running this program because of the version of numpy. This project needs a requirements.txt file.

Is there a way you can stop the server with a button on the GUI to make sure the camera is turned off? I wanted to use this because when I default the pi bootup to run the main.py script i cant find how to turn off/kill the local server main.py script since I cant see the terminal that started it

E: package libqtgui4 is not available, but is referred to by another package.

I try everything but nothing

Please help me

I do not think the software should differ based on the model this much.... did you enable some extra repos?

Hello,

Im following this project for an university project and as I said in the title, im having troubles with that instruction. It is stucked in "running setup.py bdist.wheel for opencv-contrib-python..." for more than an hour. I hope anyone can help me.

Thank you for your time!

Hi. im trying to compiling the codes 'Main and Camera' and im getting the following errors:

Camera error:

Any ideas Please?

Hi Eben, thanks for the video on how to make a remote viewable camera with raspberry pi (Beginner project). However, I've been having issues running the main.py as it keeps giving me an error with regards to numpy. I've uninstalled and installed different versions of numpy to no avail. can you please help?. I get the same error when I run the code for camera.py. Below is the error I receive when I run the main.py code.

python 3.7.3 (/usr/bin/python3)

%Run camera.py
RuntimeError: module compiled against API version 0xe but this version of numpy is 0xd

ImportError: numpy.core.multiarray failed to import

I'm trying to use the raspi minimal config to install. Everything seems to work until I try to run the main.py from your git. I get the following

root@raspberrypi:/opt# python3 ./pi-camera-stream-flask/main.py
Traceback (most recent call last):

Do you know what dependencies it is looking for?

Hello, does any one know how to fix the the capturing in my PC VNC viewer? both PC and Pi are connected via VNC Viewer. The VNC shows the the Pi screen my PC. However, once the camera is open and taking picture, this moment doesn't appear on my PC screen.

Hi! I chanced upon this project while looking for ways to link my rpi ( & pi camera) to send images continuously to my PC. The PC will then run image recognition and processing (yolov5) on it for my project.

However, most guides I came across shows the pi camera just streaming the feed to a website. Is it possible to send the images to a PC instead for processing? Is there a way I can edit your implementation for this use case? If not, are you able to provide any guidance or codes?

Thank you in advance and sorry for the trouble! Really cool project by the way!

I follow the instructions last night and there is no libqtgui4 and libqt4-test
And there is a version problem also with numpy.

So, at the end when you start with sudo python3 pi-camera-stream-flask/main.py there are some errors.
