B4J Question MP3 Duration

[derez]

I'm trying to get a MP3 file's duration using the medialayer's method, but gets NaN :

Dim uri As String = File.GetUri("E:\Music\Amit Erez","Please.mp3")
mp.Initialize("mp",uri)
mp.Play
Log(mp.Duration)

The file plays so the path is OK.

You can try

...
asJO(mp).RunMethodJO("getTotalDuration",null).RunMethod("toSeconds",null)
...
Sub asJO(o as JavaObject) as JavaObject
return o
End Sub

Also maybe try it before mp.play

Thanks, it is the same.
I tried with a Tag editor and I can see the time there...

It will return the same result (in seconds instead of milliseconds) as the Duration property.

Nan means that the duration is not yet known.

You can use CallSubPlus to check the duration 100ms after you initialize mp.

Thank you, now I get it !
The min delay is 36 ms.
