![]() The basic idea is to launch FFmpeg via a pipe, which then converts raw samples to the required format (for writing) or decodes the file into raw samples (for reading). The article describes using FFmpeg to read and write video frames in Python and there’s a link to a second article showing the same thing for audio. Read and Write Video Frames in Python Using FFMPEG. ![]() I first learned of this approach from an article on Zulko’s fascinating Python oriented blog on GitHub: Recently though, I’ve found a new way of dealing with audio and video files that is relatively painless, so I think it’s worth sharing. However, I have tended to shy away from using it for quick one-off signal processing tasks where I needed to read or write audio or video files because it always seemed like a lot of hassle figuring out which library to use and what functions to call to actually get access to the raw data. ![]() C is my favourite programming language and the one I use most often. ![]()
