AudioPlayer.getDuration gives a incorrect duration when playing .m4a files on iOS.

[itsMatoosh]

Using the AudioPlayer.getDuration method when playing a local (.m4a) file on iOS gives a duration in miliseconds which is 2 times longer than the actual duration of the track. Using the same code and the same music file on Android gives the correct duration.

Because the incorrect duration is given, the onPlayerCompletion event of the player doesn't fire at the end of the track but much later.

This could be caused by the library incorrectly reading the .m4a file metadata on iOS.

I play a mix of mp3 and m4a files using this plugin every day, and I never had a problem with the wrong duration. And none of my test users, who have different phones and iOS versions, have reported any issues related to wrong duration.

Hmm, that's weird. I'm using iPhone 6 to test the app and the problem always occurs. I ended up using a workaround where I listen to the onAudioPositionChanged stream and skip the current song when half of the given duration passes. This is not an ideal solution though :/

I have tested my app on iPhone 6, and the duration of .m4a files is correct - no workarounds necessary.

in my case it gives me negative duration. my files are mp3

[volgin]

@frediustcDev This means there is a problem in your code. The duration is correct on all files. I am using this plugin right now to listen to music :)

@itsMatoosh please follow the issue template. We need a code example + sample file + platform so I can reproduce it. Otherwise I will close this issue.

我也遇到了这个问题，网址是https://rr5---sn-i3belnll.googlevideo.com ...

该网址不起作用。它包括空格。

You can use the URL in my code
