Reverse Video Playback with OpenCV in Python
OpenCV (CV2) is a powerful library of functions for image and video processing, which can be used to perform multiple operations on videos. However, it's important to note that Python does not come with cv2 installed, so you'll need to install it separately.
Installation on Windows and Linux
To install OpenCV (cv2) on both Windows and Linux systems, use the package manager with the following command:
This command works the same way on Windows (Command Prompt or PowerShell) and Linux (terminal) systems.
After installation, verify by running Python and importing cv2, then printing its version:
This confirms OpenCV is properly installed.
Additional Considerations
For some advanced use cases, additional OpenCV packages or compilation from source may be necessary. But for general image/video processing tasks, is sufficient.
If Python or pip is not installed, install them first according to your OS prerequisites.
Using OpenCV for Video Reversal
To play a video in reverse mode using CV2, the video is broken into frames and stored in a list. After getting the list of frames, an iteration is performed over the frames, but in reverse order for the video to play in reverse.
This article focuses on the usage of OpenCV library for video reversal in Python. For more detailed information on OpenCV and its various functionalities, please refer to the official OpenCV documentation.
