Hi everyone!
I've been playing around with the idea of integrating motion tracking into the hmh engine.
Currently, I'm using the DirectShow api to get raw camera footage. The issue is that DirectShow is complete garbage, and seems deprecated.
Is there another api to get camera data?
I want the simplest thing possible, so I would definetly not use OpenCV (if possible!)

Media Foundation is the API you want. MF is api (since Vista) to deal with different kind of video/audio related things - playback, capture, encoding, decoding, etc...
What you want to look at is IMFSourceReader and IMFMediaSource.
Here are instructions how to create IMFMediaSource (representing camera): https://docs.microsoft.com/en-us/...video-capture-in-media-foundation
And here are instructions how to use IMFSourceReader to read data from it: https://docs.microsoft.com/en-us/...media-data-with-the-source-reader

I've found some of my old code that can be used as example: https://gist.github.com/mmozeiko/a5adab1ad11ea6d0643ceb67bb8e3e19
If you run it without arguments it will enumerate available devices:
To capture to file you run with that long path:
And output is written to image.jpg file.
