This is done as part of satisfying the LGPL requirements of FFmpeg. VideoWriter will throw a Python exception). But this is to be expected because it’s loaded dynamically only when needed, with a graceful failure (e.g.
The exact file name depends on the version of FFmpeg, which in turn depends on the version of opencv-python in this version particular it is: \Lib\site-packages\cv2\opencv_videoio_ffmpeg453_64.dll Opencv-python includes a build of FFmpeg as a dll.
I am using -plugin-enable=numpy -plugin-enable=anti-bloat to enable use of numpy, which is a dependancy of OpenCV for Python. OpenCV has a broader approval, being mentioned in 39 company stacks & 39 developers stacks compared to FFMPEG, which is listed in 19 company stacks and 13 developer stacks.I am using Python 3.8.11 (through Anaconda) on Windows, with packages (installed with pip, not conda): Nuitka=0.6.17.2 Lensley, Plickers, and Suggestic are some of the popular companies that use OpenCV, whereas FFMPEG is used by AmperVue, Mux, and AbemaTV. Here's a link to OpenCV's open source repository on GitHub. OpenCV is an open source tool with 36.3K GitHub stars and 26.6K GitHub forks. Enabled with OpenCL, it can take advantage of the hardware acceleration of the underlying heterogeneous compute platform.įFMPEG and OpenCV can be primarily classified as "Image Processing and Management" tools. Written in optimized C/C++, the library can take advantage of multi-core processing. OpenCV was designed for computational efficiency and with a strong focus on real-time applications.
