@otrebor4, @pchinea how to run this library? Can you please share the code?

[pchinea]

@otrebor4 I'm very very sorry, github didn't notify me about this issue and I just see this.

Those messages are absolutely normal, it is checking if the H.264 codec is available (in your case that codec is not available). If you are seeing these messages, the script was able to connect to both Telegram and your camera, so theoretically it is working correctly.

In any case, try setting the BOT_LOG_LEVEL variable to INFO and see what it displays.

@sonykurian96 This is not a library, it is a standalone application, you don't need any code. Please, follow the instructions in the README file.

[sonykurian96]

@pchinea Thank you very much for the response. But I'm bit confused on how to properly run this project(I'm getting some errors). It would be really helpful for me as well as many others if you could do a simple tutorial on how to run your project from the source code 🤝.

Hi Pablo, thanks for your attention.

What test can i perform in order to make this tool to work for me?

For example disabling the video part and let work only the foto part?

sorry, i wrote nothing but actually it is NOT making surveillance and not taking foto/video by motion in front of the camera BUT if i press /get_photo or /get_video on the telegram bot page it makes a foto or a video.

So the motion thing is not working so far....

@otrebor4 Tried today... installed ubuntu server 22.04.2 LTS..

1º It cant access to /dev/video0 for the user so... sudo useradd "youruser" video sudo chmod 777 /dev/video0 reboot...

2º error open Could not find encoder for codec_id=27, error: Encoder not found solution: change codec order (yes, opencv installed through pip has a bug) in surveillance-bot/camera.py change for codec in ['avc1', 'mp4v']: to for codec in ['mp4v', 'avc1']:

Solved, it runs... but on iPhone videos cannot be playable, only on windows/android....

@pchinea opencv installed through pip has a bug with codecs... so one way is build opencv yourself or change that codec order in your code
