+# Virtual Camera
+
+The virtual camera feature allows 3rd party application to expose a remote or
+virtual camera to the standard Android camera frameworks (Camera2/CameraX, NDK,
+camera1).
+
+The stack is composed into 4 different parts:
+
+1.  The **Virtual Camera Service** (this directory), implementing the Camera HAL
+    and acts as an interface between the Android Camera Server and the *Virtual
+    Camera Owner* (via the VirtualDeviceManager APIs).
+
+2.  The **VirtualDeviceManager** running in the system process and handling the
+    communication between the Virtual Camera service and the Virtual Camera
+    owner
+
+3.  The **Virtual Camera Owner**, the client application declaring the Virtual
+    Camera and handling the production of image data. We will also refer to this
+    part as the **producer**
+
+4.  The **Consumer Application**, the client application consuming camera data,
+    which can be any application using the camera APIs
+
+This document describes the functionalities of the *Virtual Camera Service*
+
+## Before reading
+
+The service implements the Camera HAL. It's best to have a bit of an
+understanding of how it works by reading the
+[HAL documentation first](https://source.android.com/docs/core/camera)
+
+![](https://source.android.com/static/docs/core/camera/images/ape_fwk_camera2.png)
+
+The HAL implementations are declared in: -
+[VirtualCameraDevice](./VirtualCameraDevice.h) -
+[VirtualCameraProvider](./VirtualCameraProvider.h) -
+[VirtualCameraSession](./VirtualCameraSession.h)
+
+## Current supported features
+
+Virtual Cameras report `EXTERNAL`
+[hardware level](https://developer.android.com/reference/android/hardware/camera2/CameraCharacteristics#INFO_SUPPORTED_HARDWARE_LEVEL)
+but some
+[functionalities of `EXTERNAL`](https://developer.android.com/reference/android/hardware/camera2/CameraMetadata#INFO_SUPPORTED_HARDWARE_LEVEL_EXTERNAL)
+hardware level are not fully supported.
+
+Here is a list of supported features - Single input multiple output stream and
+capture:
+
+-   Support for YUV and JPEG
+
+Notable missing features:
+
+-   Support for auto 3A (AWB, AE, AF): virtual camera will announce convergence
+    of 3A algorithm even though it can't receive any information about this from
+    the owner.
+
+-   No flash/torch support
+
+## Overview
+
+Graphic data are exchanged using the Surface infrastructure. Like any other
+Camera HAL, the Surfaces to write data into are received from the client.
+Virtual Camera exposes a **different** Surface onto which the owner can write
+data. In the middle, we use an EGL Texture which adapts (if needed) the producer
+data to the required consumer format (scaling only for now, but we might also
+add support for rotation and cropping in the future).
+
+When the client application requires multiple resolutions, the closest one among
+supported resolutions is used for the input data and the image data is down
+scaled for the lower resolutions.
+
+Depending on the type of output, the rendering pipelines change. Here is an
+overview of the YUV and JPEG pipelines.
+
+**YUV Rendering:**
+
+```
+Virtual Device Owner Surface[1] (Producer) --{binds to}--> EGL
+Texture[1] --{renders into}--> Client Surface[1-n] (Consumer)
+```
+
+**JPEG Rendering:**
+
+```
+Virtual Device Owner Surface[1] (Producer) --{binds to}--> EGL
+Texture[1] --{compress data into}--> temporary buffer --{renders into}-->
+Client Surface[1-n] (Consumer)
+```
+
+## Life of a capture request
+
+> Before reading the following, you must understand the concepts of
+> [CaptureRequest](https://developer.android.com/reference/android/hardware/camera2/CaptureRequest)
+> and
+> [OutputConfiguration](https://developer.android.com/reference/android/hardware/camera2/OutputConfiguration).
+
+1.  The consumer creates a session with one or more `Surfaces`
+
+2.  The VirtualCamera owner will receive a call to
+    `VirtualCameraCallback#onStreamConfigured` with a reference to another
+    `Suface` where it can write into.
+
+3.  The consumer will then start sending `CaptureRequests`. The owner will
+    receive a call to `VirtualCameraCallback#onProcessCaptureRequest`, at which
+    points it should write the required data into the surface it previously
+    received. At the same time, a new task will be enqueued in the render thread
+
+4.  The [VirtualCameraRenderThread](./VirtualCameraRenderThread.cc) will consume
+    the enqueued tasks as they come. It will wait for the producer to write into
+    the input Surface (using `Surface::waitForNextFrame`).
+
+    > **Note:** Since the Surface API allows us to wait for the next frame,
+    > there is no need for the producer to notify when the frame is ready by
+    > calling a `processCaptureResult()` equivalent.
+
+5.  The EGL Texture is updated with the content of the Surface.
+
+6.  The EGL Texture renders into the output Surfaces.
+
+7.  The Camera client is notified of the "shutter" event and the `CaptureResult`
+    is sent to the consumer.
+
+## EGL Rendering
+
+### The render thread
+
+The [VirtualCameraRenderThread](./VirtualCameraRenderThread.h) module takes care
+of rendering the input from the owner to the output via the EGL Texture. The
+rendering is done either to a JPEG buffer, which is the BLOB rendering for
+creating a JPEG or to a YUV buffer used mainly for preview Surfaces or video.
+Two EGLPrograms (shaders) defined in [EglProgram](./util/EglProgram.cc) handle
+the rendering of the data.
+
+### Initialization
+
+[EGlDisplayContext](./util/EglDisplayContext.h) initializes the whole EGL
+environment (Display, Surface, Context, and Config).
+
+The EGL Rendering is backed by a
+[ANativeWindow](https://developer.android.com/ndk/reference/group/a-native-window)
+which is just the native counterpart of the
+[Surface](https://developer.android.com/reference/android/view/Surface), which
+itself is the producer side of buffer queue, the consumer being either the
+display (Camera preview) or some encoder (to save the data or send it across the
+network).
+
+### More about OpenGL
+
+To better understand how the EGL rendering works the following resources can be
+used:
+
+Introduction to OpenGL: https://learnopengl.com/
+
+The official documentation of EGL API can be queried at:
+https://www.khronos.org/registry/egl/sdk/docs/man/xhtml/
+
+And using Google search with the following query:
+
+```
+[function name] site:https://registry.khronos.org/EGL/sdk/docs/man/html/
+
+// example: eglSwapBuffers site:https://registry.khronos.org/EGL/sdk/docs/man/html/
