MPMediaItem URL error #279

Closed rikola closed 8 years ago

rikola commented 8 years ago

I can't create an EZAudioFile from an MPMediaItem URL in my app. When I try to do it I get this error Error: Failed to dispose of ext audio file (-50).
Do you know how to get it to work with iTunes library URL's?

dennislysenko commented 8 years ago

One possible workaround would be to quickly copy the iTunes library URL to a file that you know EZAudioFile can work with. Here is a gist that provides a class with a single method to do just that:

I guess it would be preferable to be able to stream these MPMediaItems directly, but this should be a good enough workaround for now if it works. Also, change the audio format on line 50 to something more familiar (MP3/M4A) if it has trouble reading the PCM file, though I can't foresee that being a big issue seeing as PCM is supposedly pretty great for reading audio data.

Thanks. This looks like it will do the trick.
I'm still not sure why the ipod URL prefix breaks EZAudioFile though. Strange stuff.

Hey friends, Anybody got hold of this issue. Still get this error

Error: Failed to dispose of ext audio file (-50) error, and suspect this happens if the playing file is recorded with very small interval of 3-4 sec.
