I have heard of pygame (for games and reading from webcam) in python. And also gstreamer for media in python. Is there any python library that one can use for fingerprint reading and recognition.

My goal is to create a RTSP server using OpenCV Python using the GStreamer backend.
I have RGB images stored as OpenCV Mat, and I would like to create a VideoWriter which can write to a RTSP sink. The output video must be x264 encoded.
I believe this can be easily achieved using a GStreamer pipeline and providing the pipeline arguments to the VideoWriter constructor and then later pushing frames to the VideoWriter, but the issue is I have no experience working with GStreamer and I find it very confusing.
The answers I have found on SO are incomplete, use specific hardware decoders (ex for NVIDIA Jetson), or are overly complex. I'd like to find a more generic solution which works on CPU.
I have created a project something related to your requirement sometime ago. This could be a kickstarter and customize it based on your need. I'm attaching my github repository link below.
OpenCV RTSP Server
Any issues related to the project can be raised in the github itself and doubts can be cleared here.
SimpleRTSPServer, Not in Python but very simple to run and use. Start the server in another terminal and write your outputs to there. The server easy to configure as well. You can capture read frames easily from another Python script or VLC.
I am trying to read the stream from HDMI-USB video-capture card using opencv. But OpenCV doesn't seem to support that functionality. I used opencv to read RTSP streams and webcams. Can anyone suggest a way here. Currently I am accessing the stream using OBS Studio software. Is there any other module in python that I can use. Thanks in advance.
There's a similar question here. But that approach doesn't work for me.
Edit:
video0 or video1 depends on your system and connected devices.
Turns out we can access this USB device using opencv itself.
In linux you can access these devices at /dev/video0.
import cv2
cap = cv2.VideoCapture('/dev/video0')
I'm yet to figure out how to do this in windows though
I am creating a web application that makes animation from frames. I use opencv and VideoWriter to implement it. But there is a problem. I want to host my application on Google App Engine, so I cannot save files on it. Is it possible to output the VideoWriter video to Google Cloud Store directly, without saving it on the machine, or I must find other library to implement it?
Generally speaking, streaming transfers are supported by Cloud Storage for other languages, but for Python, or Ruby. OpenCV has C++, Python, Java and MATLAB interfaces and supports Windows, Linux, Android and Mac OS. In other words, if you don't plan to use the Python, or Ruby library version, your setup should work.
I'm looking for a Python library to communicate with Google Talk that can handle audio chat. There are plenty of them that can do text-only, but I can't find any that support audio or video. Does anyone know of one?
You need a library in Python that has bindings for jingle, which is the standard for voice over xmpp. There are build instructions available to create Python bindings.
Is there any library (or) application available in Python to support Video Streaming? It has to read the file and needs to stream over the web.

It's a streaming media server implemented in Python.
