A pure-python framegrabber for Windows
Project description
Overview
jaraco.video implements a framegrabber inteface for Windows Video Capture devices.
Status and License
jaraco.video is a port of the VideoCapture module in pure Python using ctypes and comtypes.
jaraco.video is maintained by Jason R. Coombs. It is licensed under an MIT-style permissive license.
You can install it with easy_install jaraco.video, or from the mercurial repository with easy_install jaraco.video==dev.
jaraco.video is designed to run on Python 2.6+, including Python 3, and including 32-bit and 64-bit versions of Python.
Installation
jaraco.video depends on several libraries including Pillow and comtypes. If the package is installed using setuptools or pip, those dependencies should be installed automatically.
There are some issues that prevent the released version of comtypes from installing properly. Until those issues are fixed, work around them by first installing comtypes manually from jaraco’s mirror:
easy_install https://bitbucket.org/jaraco/comtypes/get/b85ebb181c17.zip
Usage
jaraco.video includes a console script “save-frame”, which locates the first video capture device and saves a single frame to disk as “test.jpg”. The command may also be invoked thus:
python -m jaraco.video.capture
This example usage can be seen in the function jaraco.video.capture:save_frame.
History
1.2.1
Fixed several errors in the code due to untested refactorings for Python 3 support. The code now runs properly under Python 3.
#3: Added notes about deploying the latest version of comtypes with bug fixes from jaraco’s mirror.
1.2
#1: Require jaraco.util for bitutil, which has progressed with better Python 3 support.
#2: Added a hard dependency on Pillow for imaging. The library is pretty useless without it. If there is a use-case out there for using the library without Pillow, please file a request ticket.
1.1
Moved typelibs so they will be included with the build.
Fixed ImportError on Python 3.
Added readme.
1.0
First non-dev release. Typelibs are included and comtypes libs are generated automatically.
