window-recorder 0.2.1

Programatically video record a window as a context manager

Installation

This only works on Linux systems. You should have xwininfo installed by default.

pip install window-recorder

If the above does not work (OpenCV can be finicky), then you can install the dependencies manually. Install opencv and mss as dependencies (recommended with conda):

conda install opencv
conda install -c conda-forge python-mss

Then clone this repository anywhere and install locally with

pip install -e .

Usage

The WindowRecorder class comes as a context manager. You pass in a list of window names to record and it will try to find them in the order given, recording the first one with a valid window configuration.

The video will start and end recording according to the life cycle of the context manager.

from window_recorder import WindowRecorder
import time

# passing in nothing as the window name will allow you to select the window by clicking
# want to capture an RViz window, which could have name "RViz*" as well
with WindowRecorder(["RViz*", "RViz"], frame_rate=30.0, name_suffix="rviz"):
    # do things...
    time.sleep(0.1)
    start = time.time()
    while time.time() - start < 2:
        time.sleep(0.1)
