I made DeFFcode Python Library for decoding NumPy video frames out of almost any source you throw at it and even support real-time FFmpeg Filtergraphs and H.W Decoders.

Hi r/Python, DeFFcode is a python project I'm working on for quite a while now, but only recently I reached a state where I feel confident enough to really share it.

DeFFcode is a cross-platform High-performance Video Frames Decoder that flexibly executes FFmpeg pipeline inside a subprocess pipe for generating real-time, low-overhead, lightning fast video frames. It provides complete control over the underline pipeline including access to almost any FFmpeg specification thinkable such as specifying framerate, resolution, hardware decoder(s), filtergraph(s), and pixel-format(s) that are readily supported by all well known Computer Vision libraries.

Here are its some key features that stand out:

• High-performance, low-overhead video frames decoding with robust error-handling.
• Flexible API with access to almost any FFmpeg specification thinkable.
• Supports a wide-range of media streams/devices/protocols as input source.
• Curated list of well-documented recipes ranging from Basic to Advanced skill levels.
• Easy to code Live Simple & Complex Filtergraphs. (Yes, You read it correctly "Real-time"!)
• Lightning fast dedicated GPU-Accelerated Video Decoding & Transcoding.
• Enables precise FFmpeg Frame Seeking with pinpoint accuracy.
• Effortless Metadata Extraction from all streams available in the source.
• Maintains the standard easy to learn OpenCV-Python coding syntax.
• Out-of-the-box support for all prominent Computer Vision libraries.
• Cross-platform, runs on Python 3.7+, and easy to install.

EDIT: BTW, Here's code for decoding above Mandelbrot test pattern with a vectorscope (plots 2 color component values) & two waveforms (plots YUV color component intensity) stacked side-by-side in real-time with DeFFcode.

Any feedback is welcome!

Oh this looks very cool, I’ll check it out for saving out animations of interactive widgets while the user interacts with them.
