The purpose of :
Publish a program that can play background music,

:
Such as using qt development played a music program, but the use of QMediaPlayer will report a series of errors, check the problem seems to be system environment (play), so if solve the environmental problems, the program used to issue, to the new environment also can not guarantee the normal play?

So if the use of third-party tools to play, such as aplay, play, such as ffmpeg tools, so is every release program these tools must be packaged in together?

Linux platforms have very lightweight, and can support a variety of audio coding format playback tools?

If there are other solutions, also please great god glad, thank you!
