Tizen Native API  5.5

It provides capability information of the media recorder.

Required Header

#include <recorder.h>

Overview

The Capability API allows you to retrieve the recorder capabilities mentioned below:

  • Supported file formats
  • Supported audio and video encoders

To get all supported file formats, call recorder_foreach_supported_file_format(). This function will internally invoke recorder_supported_file_format_cb() for each file format.

This API is related with the following features:

It is recommended to design feature related codes in your application for reliability.
You can check if a device supports the related features for this API by using System Information, thereby controlling the procedure of your application.
To ensure your application is only running on the device with specific features, please define the features in your manifest file using the manifest editor in the SDK.
More details on featuring your application can be found from Feature Element.
