When I turned up the buffer of the mixer, the delay ~~disappeared~~ decrease

I'm guessing it's get_pos using the now_time-start_time timing method, but there's a delay in updating the audio buffer

use_time will be different from the actual length of the music, but I can't remember if it's bigger or smaller

  There is a real error, about 500ms every 300s, but it only happens in MP3 format i convert vm to mp3 using ffmpeg.

The audio speed is about 1.0016 times, which is very important in music games

When I only get his duration, it turns out to be wrong 

ffmpeg says it has 302.52s, so sdl2-mixer is wrong.

It's also wrong when I use 2.7.2 

I'm guessing it's also a problem with the sample rate, but it seems like a possibility
