Ocean is the in-house framework for Computer Vision (CV) and Augmented Reality (AR) applications at Meta. It is platform independent and is mainly implemented in C/C++.
Provide API for enumerating camera devices and video formats the support
Motivation & Examples
I'm working on musical app idea that needs to process video stream with lowest latency possible. In native iOS I usually want 640x480 at 120fps with highest Fov. Would great to have option to iterate all devices and their respective formats. Also utility method to choose configuration the closest to requested:
camera position (front, back, external, unknown) and
width, height or image aspect ratio and
fps and
fov
with maybe some optional flag what we want to prioritise such as PRIORITY_HIGHEST_FRAMERATE, PRIORITY_HIGHEST_RESOLUTION

Data models could be even basic for now, similar to those at OpenFrameworks: https://openframeworks.cc///documentation/video/ofVideoDevice/ https://openframeworks.cc///documentation/video/ofVideoFormat/
