CeLux is a high-performance Python library for video processing, leveraging the power of FFmpeg. It delivers some of the fastest decode times for full HD videos globally, enabling efficient and seamless video decoding directly into PyTorch tensors.
The name CeLux is derived from the Latin words celer
(speed) and lux
(light), reflecting its commitment to speed and efficiency.
- ⚡ Ultra-Fast Video Decoding: Achieve lightning-fast decode times for full HD videos using hardware acceleration.
- 🔗 Direct Decoding to Tensors: Decode video frames directly into PyTorch tensors for immediate processing.
- 🖥️ Hardware Acceleration Support: Utilize CUDA for GPU-accelerated decoding, significantly improving performance.
- 🔄 Easy Integration: Seamlessly integrates with existing Python workflows, making it easy to incorporate into your projects.
