+* The reason of this fork is to develop a RTMP Flutter plugin. For the camera preview of this plugin, we have to access HKView currentSampleBuffer when a new frame has been generated by the camera.
 * Camera and Microphone streaming library via RTMP, HLS for iOS, macOS, tvOS.
 * Issuesの言語は、日本語が分かる方は日本語でお願いします！
