Say if I am in a meeting on Microsoft Teams with my web camera ON, is it possible to live edit the webcam input in Python and then show it as an output to the other meeting members as my webcam video? Is it possible to do this in OpenCV?
I know that the webcam video can be edited with OpenCV, but how do I show the edit as my webcam output live on the MS Teams meeting?
Thank you.

I've been searching for quite some time now, but the only example I've seen where camera motion keyframes (movements) can be extracted from a video is in blender. I'm looking for a script, library, colab notebook, or any recommendation to be able input a video (for example, getting the camera keyframe movements from a video of a drone flying around) and exporting it to any type of file. The main purpose of this is double-sided: I want to be able to take the camera keyframe movements from the drone video and input it into an AI Art Animation and I want to be able to learn and add this python tool or library into a colab notebook of AI tools I've been slowly building over the months. Any help from you masterful wizards will be appreciated. Thanks!
I'm a "hacker", "novice-intermediate" level python coder, meaning I can read code and understand most basic and some advanced type coding. I'm able to read code quite well and manipulate it to my preferences, but I just don't even know where to start when it comes to the request I'm asking, ergo my post to Stack.
I am trying to stream live video from an external camera using cv2. I was able to write the simple code to stitch the frames and stream it. But am struggling to find how to change the camera.
I tried to run it after disabling the main webcam from the task manager, but it still did not work.
So, if anyone can help me with some clue regarding the same, that would be a great help.
Cameras are numbered for Windows. You can try a few indeces and check which camera index belongs to the camera you want.
capture = cv2.VideoCapture(index)
any help is much appreciated. I've been looking for a few days for something to meet the following use case. I need to open a single video player window which will play a dynamic stream of videos selected by an accompanying program. I'm on windows 10 but could probably find a way to use linux if needed.
So the flow would be as such:
Video 1 opens in the video player window.
On a queue sent by the same script which started the previous step, Video 1 is paused/stopped and Video 2 is played in this same window with a seamless frame to frame zero transition time.
The script in the background does some additional processing to decide whether it wants to next play Video 3, Video 4, or Video 5. Let's say the script chooses Video 5.
Now on conclusion of Video 2 we want to tell this same window to play video 5, again with seamless frame to frame zero transition or black screen.
Does anyone know how to do this? I've not been able to figure it out with python-vlc, OpenCV, or anything else! Please Help! Thanks!
I found this PyQt5 code (How to play multiple clips of a video one after another see ekhumoro's answer), which appears to play one video after another. However, the media is given to the window before calling app.exec()... How do I update the media source dynamically as the window is already open and playing media? AKA after app.exec() has been called?
I need to display the USB camera video of raspberry-pi in Wxpython with control buttons in it. I have managed to embed vlc in to Wxpython with control buttons (Got it from Google) to play existing video. Is there any way to stream the USB camera video in it?
Thanks in advance :)
If you've managed to embed VLC, you should just be able to point it at the v4l address for the webcam.
The v4l address should be along the lines of v4l:/dev/video0:size=640x480 (but it'll vary depending on your machine I guess). You may find it easier to use the standalone VLC client to get the address you need and then put it into your program.
This StackOverflow thread may be useful for later depending on what you're doing.
I have an ASUS Xtion 3D Sensor Camera. I want to record video with this camera by using python.
I have tried opencv using this tutorial; http://docs.opencv.org/2.4/doc/user_guide/ug_kinect.html, but it seems that there is no video recording by using OpenNI API through OpenCV. It only shows that how to grab frames, but that is not video recording.
How can I manage to make a video recording with this camera in python?
Thanks,
You can use Recorder class to capture data into ONI file.
http://www.openni.ru/wp-content/doxygen/html/classopenni_1_1_recorder.html
Then you can convert ONI into avi format https://github.com/KirillLykov/oni2avi
