### Using AVFoundation to Capture Images and Movies
|
||||
## Using AVFoundation to Capture Images and Movies
|
||||
|
||||
AVCam demonstrates how to use the `AVFoundation` capture API to record movies and capture still images. The sample has a record button for recording movies, a camera button for switching between front and back cameras (on supported devices), and a still button for capturing still images. AVCam runs only on an actual device, either an `iPad` or `iPhone`, and cannot be run in `Simulator`.
|
||||
|
||||
### Build Requirements
|
||||
|
||||
Xcode 9.0, iOS 11.0 SDK
|
||||
|
||||
### Runtime
|
||||
|
||||

# MusicKitSample
|
||||
|
||||
MusicKit on iOS lets users play Apple Music and their local music library natively from your apps and games. When a user provides permission to their Apple Music account, your app can create playlists, add songs to their library, and play any of the millions of songs in the Apple Music catalog. If your app detects that the user is not yet an Apple Music member, you can offer a trial from within your app.

|
|||
|

After requesting access to the Camera, this application shows a live video feed, as well as a thumbnail of frames being sent to the Vision namespace. The thumbnail shows the results of the image-processing pipeline and is helpful for developers who modify the `VideoCaptureDelegate.CroppedSampleBuffer` method to remove or enhance edge detection or see if it's useful to try other techniques such as dilation, contrast enhancement, thresholding, and so forth.
|
||||
|
||||
The app first runs in a "scanning" mode, when it is detecting rectangles. Detected rectangles are outlined in blue. Touch inside a detected rectangle to activate "tracking" mode. In this mode, the tracked rectangle's bounding box is outlined in either green, yellow, or red, depending upon the confidence of the Vision namespace. (Note that this uses `VNDetectedObjectObservation` observations rather than `VNRectangleObservation` observations, which seem to be more "fragile" in terms of tracking.)

|

|

You'll notice that "tracking" mode isn't noticeably faster or more accurate than "scanning" mode. What tracking _does_ provide is the same object identity over subsequent frames which you can access via the [VNObservation.Uuid](https://developer.xamarin.com/api/property/Vision.VNObservation.Uuid/) property.

This sample requires a device that supports ARKit's "object scanning" configuration (`ARObjectScanningConfiguration`). This configuration is processor-intensive and may not be supported or may not produce adequate tracking on older hardware. This configuration also "disables ARKit features not necessary for reference object scanning," and should only be used for, essentially, the use-case embodied in this app.
|
||||
|
||||
The app is used by developers to scan a real-world object to create an `ARReferenceObject` definition that can be saved to a file and used in end-user mixed-reality apps (for instance, recognizing a sculpture or factory-floor machine).

After ARKit initializes, a "ghost" bounding box will appear and try to fit around any object that is in the middle of the screen. Use pinch, pan, and two-finger pan to adjust the size of the bounding box until it is sufficient to encompass the scanned object. Points will appear within the bounding box, showing how well the object is being detected.

## Notes

|

### Manual resource management in ARKit and SceneKit apps
|
||||
|
||||
In ARKit, it's crucial to manually manage resources. Not only does this allow high frame-rates, it actually is _necessary_ to avoid a confusing "screen freeze." The ARKit framework is lazy about supplying a new camera frame (`ARSession.CurrentFrame`). Until the current `ARFrame` has had `Dispose()` called on it, ARKit will not supply a new frame! This has the appearance of the video "freezing" even though the rest of the app is responsive. The solution is to always access it with a `using` block (see `ViewControllerSCNViewDelegate.Update` in this example) or manually call `Dispose()` on it.
|
||||
|
||||
Beyond the `ARSession.CurrentFrame`, the major resource that needs to be managed carefully in this app are instances of `PointCloud`. This is a visualization of the raw feature points being sensed by ARKit. While this is not called _every_ frame, it's called often enough that it would lead to significant memory consumption. You'll note that prior to the factory method `PointCloud.CreateVisualization` is called, the app takes care to call `Dispose()` on the current `PointCloud`.

You'll note that prior to the factory method `PointCloud.CreateVisualization` is called, the app takes care to call `Dispose()` on the current `PointCloud`.
|
||||
|
||||
Another complex use of `Dispose()` relates to notifications. The Apple design uses the Observer pattern to subscribe to various state changes (e.g., `NSNotificationCenter.DefaultCenter.AddObserver(Scan.ScanningStateChangedNotificationName, ScanningStateChanged);` ). You _must_ unsubscribe from such observations while `Dispose()`ing your object or you will get a segfault when the system attempts to alert your now-deallocated object of the notification. The pattern is simple:

The pattern is simple:
|
||||
|

class MyClass : NSObject
|
||||
```csharp
|
||||
class MyClass : NSObject
|
||||
{
|
||||
private NSObject notificationObservationHandle;
|
||||
|
||||
MyClass()
|
||||
{
|
||||
private NSObject notificationObservationHandle;
|
||||
notificationObservationHandle = NSNotificationCenter.DefaultCenter.AddObserver(notificationName, NotificationHandler);
|
||||
}
|
||||
|
||||
MyClass()
|
||||
{
|
||||
notificationObservationHandle = NSNotificationCenter.DefaultCenter.AddObserver(notificationName, NotificationHandler);
|
||||
}
|
||||
|
||||
private bool disposed = false;
|
||||
override protected void Dispose(bool disposing)
|
||||
private bool disposed = false;
|
||||
override protected void Dispose(bool disposing)
|
||||
{
|
||||
if (!disposed)
|
||||
{
|
||||
if (!disposed)
|
||||
if (disposing)
|
||||
{
|
||||
if (disposing)
|
||||
{
|
||||
NSNotificationCenter.DefaultCenter.RemoveObserver(notificationObserverHandle);
|
||||
}
|
||||
disposed = true;
|
||||
base.Dispose();
|
||||
NSNotificationCenter.DefaultCenter.RemoveObserver(notificationObserverHandle);
|
||||
}
|
||||
disposed = true;
|
||||
base.Dispose();
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
Note that when implementing the `Dispose` pattern in Xamarin, you must set `disposed = true` prior to calling `base.Dispose()` in objects that are derived from `NSObject`. Xamarin's implementation of `NSObject.Dispose()` calls `Dispose(true)`, which will cause the stack to overflow if `disposed` is not already set.
|
||||
|
||||
Related: There are more shared references within the Swift code than I'd prefer, so I tried to convert as many as possible into properties with `private` setters.
|
||||
|
||||
### Fast, unsafe code to create `PointCloud`
|
||||
|
||||
Because the `PointCloud` is a short-lived object reflecting complex geometry (the raw feature points that ARKit is seeing within the target bounding box), I use `unsafe` code to create it directly from an `NVector3` array rather than loop over each `NVector3`, allocate an `SCNSphere` for that point, add that sphere to the current `SCNNode` etc.
|
||||
|
||||
The `PointCloud.CreateVisualization` combines two techniques to create complex `SCNGeometry` as quickly as possible: first, the array is pinned and accessed as an `NSData` byte buffer. Second, a template `SCNGeometryElement` is created and the data buffer and the template are "zipped together" using `SCNGeometry.Create(SCNGeometrySource[], SCNGeometryElement[])`.
|
||||
|
||||
This is a good technique to have in your toolkit.

|
||||
|
||||
### The threshold-aware gestures are nice
|
||||
|
||||
The gestures for moving and rotating the bounding box and origin only respond to touches that have either moved or rotated more than some threshold amount. The code in `ThresholdPanGestureRecognizer`, `ThresholdPinchGestureRecognizer` and `ThresholdRotationGestureRecognizer` should be quite reusable.
|
||||
|
||||
### Matrix types and performance
|
||||
|
||||
In any 3D application, you're going to be dealing with 4x4 transformation matrices. In SceneKit, these are `SCNMatrix4` objects.
|
||||
|
||||
The `SCNNode.Transform` property returns the `SCNMatrix4` transform matrix for the `SCNNode` _as backed by_ the row-major `simdfloat4x4` type. So, for instance:
|
||||
The `SCNNode.Transform` property returns the `SCNMatrix4` transform matrix for the `SCNNode` _as backed by_ the row-major `simdfloat4x4` type. So, for instance:
|
||||
|
||||
var node = new SCNNode { Position = new SCNVector3(2, 3, 4) };
|
||||
var xform = node.Transform;
|
||||
Console.WriteLine(xform);
|
||||
// Output is: "(1, 0, 0, 0)\n(0, 1, 0, 0)\n(0, 0, 1, 0)\n(2, 3, 4, 1)"
|
||||
```csharp
|
||||
var node = new SCNNode { Position = new SCNVector3(2, 3, 4) };
|
||||
var xform = node.Transform;
|
||||
Console.WriteLine(xform);
|
||||
// Output is: "(1, 0, 0, 0)\n(0, 1, 0, 0)\n(0, 0, 1, 0)\n(2, 3, 4, 1)"
|
||||
```
|
||||
|
||||
As you can see, the position is encoded in the bottom row's first 3 elements. This might be transposed (sideways) to your expectations. The functions `SCNMatrix4 ToSCNMatrix4(this NMatrix4 self)` and `NMatrix4 ToNMatrix4(this SCNMatrix4 self)` use the `M{col}{row}` fields to assure the values are proper, so that's fine, but there _is_ a small performance cost to changing the representation, so avoid needless conversions.

|
|||
An alternate possibility would be to re-acquire the reference in the `CreateReferenceObject` handler (i.e., rather than pass in `boundingBox` make another call to `ScannedObject.EitherBoundingBox`) but I’m not sure if there are no consequences to the reference changing during the asynch period of `CreateReferenceObject()`.
|
||||
|
||||
### SimpleBox<T>
|
||||
The class `SimpleBox` is used to wrap .NET value objects in an `NSObject` that can be stored in iOS `NSDictionary` objects and used in the payload for `NSNotification` objects. It is helpful but should be used sparingly, as it will cause Ahead-of-Time compilation (AoT) to generate at compile-time the variations for all the different values of `T`.

|

### Classes in the `Controllers` directory
|
||||
The Swift code uses five files to organize the behavior of the single class `ViewController`. In C# these would be called "partial classes." I put the code in different classes, as this makes it easier to reason about the state and responsibilities of each individual class.

|

I chose to use the former solely because the pattern matching form is still relatively new and therefore might be less familiar to some developers.
