    - Camera Developer's Guide
      The Camera library abstracts the complexity of interfacing with a camera connected to the target board.
      - Camera Library Overview
        The Camera library provides applications with an interface to interact with cameras connected to your system. The library supports up to 64 cameras but the actual limit depends on your hardware platform's limitations and resources.
      - Viewfinder Window
        By default, the Camera library creates a viewfinder window.
      - Settings on the Camera
        You can configure various settings on the camera to modify the ISO, aperture, shutter speed, framerate, resolution, format, etc.
      - Image Buffer Access
        The Camera library supports read-only and read-write access to the image from different stages in the imaging datapath. Applications access image buffers by binding callback functions or events to a particular stage of the imaging datapath. Alternatively, applications can use streams from the Screen API to access buffers. In this guide, access to the imaging datapath is referred to as image buffers.
      - External Camera Drivers
        Cameras that aren't already supported by the Sensor Framework for QNX SDP can be supported by an external camera driver library.
      - Show a Video Stream from a Camera
        You can use the Camera library to show a video stream (image buffers) from a live camera or file camera. This section shows you the basic workflow for doing so.

camera_h264avc_profile_t

The supported profiles for H.264/AVC

Synopsis:

#include <camera/camera_h264avc.h>

typedef enum {
    CAMERA_H264AVC_PROFILE_AUTOMATIC = 0,
    CAMERA_H264AVC_PROFILE_BASELINE,
    CAMERA_H264AVC_PROFILE_HIGH,
    CAMERA_H264AVC_PROFILE_CONSTRAINEDBASELINE,
    CAMERA_H264AVC_PROFILE_CONSTRAINEDHIGH,
    CAMERA_H264AVC_PROFILE_MAIN,
    CAMERA_H264AVC_PROFILE_EXTENDED
} camera_h264avc_profile_t;

Data:

CAMERA_H264AVC_PROFILE_AUTOMATIC: The encoder automatically selects the profile based on the configuration and video resolution.
CAMERA_H264AVC_PROFILE_BASELINE: Baseline profile of H.264/AVC.
CAMERA_H264AVC_PROFILE_HIGH: High profile of H.264/AVC.
CAMERA_H264AVC_PROFILE_CONSTRAINEDBASELINE: Constrained Baseline profile (CBP) of H.264/AVC.
CAMERA_H264AVC_PROFILE_CONSTRAINEDHIGH: Constrained High profile (CHP) of H.264/AVC.
CAMERA_H264AVC_PROFILE_MAIN: Main profile of H.264/AVC.
CAMERA_H264AVC_PROFILE_EXTENDED: Extended profile of H.264/AVC.

Library:

libcamapi

Description:

These are the acceptable values for the CAMERA_H264AVC_PROFILE parameter in a parameter-value pair. For information about these profiles, refer to the H.264/AVC standard. Use camera_get_supported_videoencoder_parameter_values() to determine the supported values at runtime.
