Is it possible to create a screen recorder in python, I found a way to capture still images, can I compile these images into a video format? Is there anything framework I can use? thank you for any suggestions, here is the script for single images:
from PIL import ImageGrab
import time
time.sleep(5)
ImageGrab.grab().save("screen_capture.jpg", "JPEG")
Yes, you can compile them to video format. FFMPEG is a phenomenal command-line tool that can be run from inside python provided it is installed and on your path.
Here is a great tutorial on how to take still images and turn them into a video:

I dont know what to import and how to do this. How do I print and add a image in python.
I have tried nothing im just looking for suggestions.
In the console it's impossible, but you can use OpenCV, PIL, or matplotlib to display images.
With OpenCV you can display the pixel value in the console:
If you are interested in image manipulation check out Pillow. It's an image manipulation/processing library.
You can install it with:
python -m pip install Pillow
To load an image and show it use this:
from PIL import Image
im = Image.open("image.png")
im.show()
For more examples and information check out the official documentation.
I am trying to open an image using pyautogui so i can compare the images pixels. I have looked in the auto correction in visual studio code and I looked in a documentary about it. Can someone please tell me how to do it?
well you can do it by PIL (pillow) like -
from PIL import Image
im = Image.open(r"path\to\image.png")
im.show()
I am trying to setup My Ubuntu Desktop wallpaper that accepts a Live video feed from webcam using opencv and after performing some object detection I accept it as Opencv feed where I am able to Display it using cv2.imshow.
But instead of Using Imshow is it possible to cast the output of object detection as ubuntu desktop live Wallpaper.
I am even able to setup live video from youtube as Ubuntu live wallpaper using cvlc but unable to understand how to do that from opencv output.
You might have to go with a lot of trouble as looks like its never been implemented but you can try implementing by one of the following ways :
Try saving the frames and consciously deleting the old frame at a
same time changing background from os call.
if you are able to make cvlc run You can try running it by cv::VideoWriter or Streaming
video to localhost and then using similar YouTube approach you
were doing.
You can Try using Streamlink/MPV/Xwinwrap fork.
You can save the desired results using cv2.imwrite() and then try the methods described here and here
I want to make an application with Kivy that can manipulate videos, my problem is that i can't play videos when i am using kivy, my operating system is Windows7.
In the demo example given with Kivy, here is the result :
in this youtube video (https://www.youtube.com/watch?v=8zSNzUAfohA), in minute 1h18min30sec the video is actually working
The result i had before was this picture :
I hope u guys know what is the problem source.
Thank you for your time :)
Install kivy.deps.gstreamer if you don't have it yet. Catalog should then work.
The second image looks like you have non-existing files included.
I would like to load a video file's frames into a numpy array. I want the frames to be properly upright, which means I need to read the orientation metadata in the video file, and rotate the loaded frames accordingly.
I have a means of loading the frames (opencv's python bindings), so all I need is a way to read the video file's orientation metadata.
I'm trying to read a .MOV file recorded off my iPhone, in python running on an Ubuntu 14.04 machine.
Stuff I've looked at:
opencv: no way of inspecting video orientation
hachoir-metadata: doesn't display orientation metadata
enzyme: only works on .mkv files, AFAICT.
ffmpeg: no longer available as a stand-alone executable on Ubuntu's repositories. This is a dealbreaker since I'd rather just hand-specify the rotation rather than go through the trouble of compiling ffmpeg from source just to get video orientation.
PIL, pyexiv: AFAICT, only loads image files.
I'm running the code on an Ubuntu 14.04 machine, so I'm looking for libraries or command-line programs available on that platform.
Any pointers would be greatly appreciated.
We use MediaInfo (libmediainfo)
it is running both on Windows and Ubuntu, and you can get all you need (codec, aspect, fps, bitrate, orientation...).
use qtrotate. It's just one file, and it works on .Mov files
