C# wrapper to Broadcom's MMAL with an API to the Raspberry Pi camera.
When starting the code example below, and attaching the visual studio debugger over ssh, the program quits after ~2 seconds (due to 'Task.Delay`) with this output ``` Waiting for debugger...

Hi, I was realy frustrated about the bullseye 64 bit implementation, which I need to run a onnx recognition under c#. I tried running the new tools libcamera-still and after...
I have a .NET 5 app, referencing MMALSharp v0.6, building and running on Pi 4 (2Gb) Raspbian Lite, copypasted default motion detection example verbatim from https://github.com/techyian/MMALSharp/wiki/Advanced-Examples/93b717ebbf4502f3a6c1ef99137a6b416dd0c3e6#FrameDiffDetection , getting an exception:...
It appears that MMALSharp is currently not working with Bullseye. This OS update brought some major changes to the camera libraries so this is not wholly unexpected. We get: `System.TypeInitializationException:...
The library uses `List` buffers and I believe the `List` default constructor only allocates enough space for 10 entries. Given the size of MMAL buffers and camera frames, we should...

Is it possible to use the sobel line detection in video mode and display in preview?
Hello, I'm running the following code on my Raspberry Pi: ``` public static async Task CaptureRawData() { MMALCamera cam = MMALCamera.Instance; MMALCameraConfig.StillEncoding = MMALEncoding.BGR24; MMALCameraConfig.StillSubFormat = MMALEncoding.BGR24; using (var imgCaptureHandler...
