GIFT-Grab is an open-source C++ and Python API for acquiring, processing and encoding video streams in real time.
GIFT-Grab supports several frame-grabber cards, standard-compliant network streams and video files.
The Python API is compatible with NumPy and SciPy.
Please note that currently only Python 2 is supported.
Features
Capturing video streams using frame-grabber hardware, the following cards are supported:
Epiphan DVI2PCIe Duo
Blackmagic DeckLink SDI 4K
Capturing standard-compliant network video streams
Reading (decoding) video files
Writing (encoding) video files (including real-time encoding), the following formats are supported:
Xvid-encoded AVI
HEVC (H.265)-encoded MP4
VP9-encoded WebM
Video data as NumPy arrays to facilitate processing with NumPy-compatible Python libraries
