QNX Advanced Virtualization Frameworks User's Guide
This User's Guide is aimed at all systems integrators and developers who want to design and build embedded systems using the QNX Advanced Virtualization Frameworks.
Camera Sharing
The Shared Video and Camera framework allows the host and guests to share the same camera.
Required components
To use the camera-sharing framework in a QNX Hypervisor system, your guest and host images must contain certain components, and you must add the virtio-video-camera vdev to the guest's VM.

QNX Momentics IDE User's Guide
This User's Guide describes version 7.1 of the Integrated Development Environment (IDE) that's part of the QNX Momentics tool suite.
QNX Software Development Platform
QNX SDP is a cross-compiling and debugging environment, including an IDE and command-line tools, for building binary images and programs for target boards running QNX Neutrino 7.1.
QNX Hypervisor
The QNX Hypervisor allows you to run multiple OSs on a target system so you can separate critical and non-critical functions, support a wide variety of applications, and reduce hardware costs.
QNX Software in the Cloud
QNX Software in the Cloud enables developers to use the QNX software in Amazon Web Services (AWS) and Microsoft Azure (Azure).
QNX Advanced Virtualization Frameworks User's Guide
This User's Guide is aimed at all systems integrators and developers who want to design and build embedded systems using the QNX Advanced Virtualization Frameworks.
- QNX Advanced Virtualization Frameworks Architecture
  The QNX Advanced Virtualization Frameworks allow you to build systems that share resources such as graphics, audio, and input devices among multiple OSs, while separating the management of critical services and non-critical services to mitigate the effects of faults.
- Audio Sharing
  The Shared Audio framework allows guests to capture and output audio on devices connected to the hypervisor host. It does this by providing an audio virtual device through which guests can start and stop these operations and configure parameters such as sampling rate.
- Camera Sharing
  The Shared Video and Camera framework allows the host and guests to share the same camera.
  - Framework architecture
    The camera-sharing framework provides a virtual device (vdev) that lets guest applications access and stream the display of a camera that's connected to the host. The framework uses components from other QNX products to interact with the camera and display its video frames.
  - Required components
    To use the camera-sharing framework in a QNX Hypervisor system, your guest and host images must contain certain components, and you must add the virtio-video-camera vdev to the guest's VM.
  - vdev virtio-video-camera
    Implements VirtIO-Video camera functionality for guests running in hypervisor VMs
- Filesystem Sharing
  The Shared Filesystem framework allows guests to access directories on the host through mountpoints of their choosing. The framework does this by providing a virtual filesystem device through which guests can interact with files in shared host directories as though they were local files.
- Graphics Sharing
  Graphics sharing is supported by the Shared GPU and Display framework. This framework supports sharing graphical content between the host and guests, and includes a virtual device, virtual rendering libraries, and other services.
- Input Sharing
  The Shared Input framework allows guests and the hypervisor host to share access to input devices. Specifically, it provides a virtual device that lets guests access input from physical devices connected to the hypervisor host.
- Sensor Sharing
  The Sensor Sharing framework allows guests to read data from sensors connected to the hypervisor host. Sensor support will vary. Presently, the framework allows guests to access Inertial Measurement Unit (IMU) sensors on the hypervisor host.
- USB Sharing
  The Shared USB framework allows guest and host applications to share access to USB devices. Specifically, it provides a virtual device that lets guests access USB devices connected to the hypervisor host.
- Virtual Socket
  The Virtual Socket framework provides a simple mechanism for passing data between the host and a guest, or between guests, independently of network protocols.
- VPU Sharing
  The Shared Video and Camera framework allows guests to use the video processing unit (VPU) on the host system to decode video. The framework does so by providing a virtual video device that provides media codec and video control functionality to client guest applications and uses the host system's VPU to do the required codec operations.
- Integration Support for Android
  The QNX Advanced Virtualization Frameworks support integrating Android into a QNX Hypervisor system with minimal changes to the Android Operating System. This is possible by supporting common Android OS versions and services, adhering to industry standards for virtualization, and allowing existing components to be reused unmodified. There's also a demonstration system that shows how applications in an Android guest can use the virtualization frameworks.
Typographical Conventions, Support, and Licensing
This section describes the typographical conventions used throughout the documentation and explains how to obtain technical support.

Required components

To use the camera-sharing framework in a QNX Hypervisor system, your guest and host images must contain certain components, and you must add the virtio-video-camera vdev to the guest's VM.

Host components

You must have the following components on your host:

the module implementing the camera vdev, vdev-virtio-video-camera.so. This file must be included in the shared objects list of your hypervisor host buildfile.
the virtio-video-camera vdev must be specified in the configuration file for each VM (i.e., qvm process) that will host a guest that wants to use this vdev. For information on how to configure this vdev, see vdev virtio-video-camera.
the path to the configuration file (*.qvmconf) for each VM. This path must be included in your hypervisor host buildfile.
a sensor configuration file (e.g., /etc/system/config/sensor.conf) containing your configuration for any cameras that you want to make available to guest applications. The path to this file must be included in your hypervisor host buildfile.
the Camera library and Sensor service (which are part of the Sensor Framework middleware). These components must be included in your hypervisor host buildfile.
For information about installing Sensor Framework on your development host (so you can then add it to your host image), see the Release Notes.
a graphics configuration file (e.g., graphics.conf) containing your Screen configuration for the host. This file must be included in the host buildfile. The Screen Graphics Subsystem is included in any hypervisor host BSP and is therefore included in the default image.

For general information on how to configure your hypervisor host, see the Configuration section of the QNX Hypervisor User's Guide.

Guest components

Because the virtio-video-camera vdev is a para-virtualized device, the guest must have a camera driver that complies with the VirtIO-Video message standard to communicate with the vdev.
