MMALSharp is an unofficial C# API for the Raspberry Pi camera. Under the hood, MMALSharp makes use of the native MMAL interface designed by Broadcom.
The project is in early stages of development, however the ability to take pictures and record video is working as expected (H.264 & MJPEG).
MMALSharp supports the following runtimes:
- Mono 4.x
- .NET Core 2.0 (beta) with .NET Standard 1.6.
For full installation instructions for Mono 4.x and .NET Core, including configuration and examples - please visit the Documentation site.
So far, the library has been tested on the following Raspberry Pi devices:
- Raspberry Pi 1 Model B (512mb)
- Raspberry Pi Zero
- Raspberry Pi 2 Model B
Both the SUNNY and Sony IMX219 camera modules are working as expected.
Tested image 'still' features:
- Image width/height
- Image encoding
- Brightness
- Contrast
- Saturation
- Sharpness
- Shutter speed
- ISO
- Exposure compensation
- Exposure mode
- Exposure metering mode
- Raspistill supported image effects
- Rotation
- Flips
- Annotate
- Dynamic range compression
- Stats Pass
- Colour effects
- Crop
- Auto white balance mode/gains
- EXIF tags
- Raw capture
When using more resource intensive encoders such as MMAL_ENCODING_BMP and the Sony IMX219 module, I've found it necessary to increase the memory split to around 200mb or otherwise you'll receive an ENOSPC error due to insufficient resources.
There is an issue with EXIF and Annotation support under the .NET Core build of MMALSharp currently, an issue has been raised for this and will be fixed ASAP.

Dave Jones @waveform80 - your Python header conversions have saved me numerous hours so far. Thank you very much.
