ffmpeg-python: Python wrapper for building FFmpeg filter graphs

What it supplies: ffmpeg-python is a Python wrapper for FFmpeg that the README says handles both simple and complex signal graphs, where other wrappers lack complex filter support. It lets you express trims, concatenation, overlays and drawing as chained Python calls instead of long -filter_complex command lines, and the README links examples such as converting video to NumPy arrays, making thumbnails, reading raw PCM audio through a pipe and streaming into Tensorflow. Useful for: - Script repetitive edits like trimming, concatenating, flipping and overlaying clips. - Generate thumbnails or extract frames for analysis. - Pipe decoded frames into NumPy or ML code. First action: - Install FFmpeg and make sure it is on the PATH. - Run pip install ffmpeg-python. - Try the README's quickstart: ffmpeg.input('input.mp4'), then hflip, output and run. Prerequisites and limits: FFmpeg must be installed and accessible through the PATH environment variable before use. The README gives no Python version in the text read. - It builds command lines for FFmpeg rather than reimplementing it, so FFmpeg's own behaviour and codecs apply. - The README shows no active-maintenance statement in the text read. This README does not state a licence in the text read here, so check the repository's licence file; FFmpeg itself has its own licence terms. Media you process carries its own rights. Written from the README text only. Statements are as the README gives them; nothing was installed or run.
