 Summary of the bug:
 An error occurred during aac playback in the latest version of the chrome
 browser from Feb 2018.
 In some cases, changing bitrate option will return to normal.
 This uploaded sound source file has all failed the aac with option 320k,
 330k, and 340k bitrate.
 Normally played in the 256k bitrate option.

 Is it encoder problem of ffmpeg? decoder problem in chrome browser? or
 problem with the sound file?


 Enviroment:
 - OS : MS Windows 7
 - Chrome version : 67.0.3396.62
 - Drag and drop the aac sound file on chrome browser.
