Using "convert" from iTunes with ScriptingBridge
-
I am trying to use ScriptingBridge to control iTunes to convert and
import an aiff file generated by my application, and failing.
I have the file stored as an aiff on disk and the correct file name as
an NSString. I also have an iTunesApplication instance up and working.
However when I add the file name (as NSString) to an NSArray and call
convert with it, nothing crashes but nothing seems to happen.
An iTunes Track is successfully returned from the convert call but if
I NSLog the returned object, I get this:
2008-02-06 19:11:01.317 TunesSampleApp[12073:613] (
)
I have pastie'd the code I am using here (I realise the Array building
could be more efficient but I wanted to make sure i was drop dead
simple for the example):
http://pastie.caboo.se/148337
As far as I can see, there is no documentation about what type the
entries in the NSArray have to be to be accepted by iTunes or any
documentation really on what convert should actually do.
For all I know it could be converting the file but not adding it to
iTunes and just storing it somewhere on the disk? Is there any
documentation other than the sdef and .h files for the API's with
ScriptingBridge?
Thanks in advance
Dave

If no-one knows what is going on with this problem specifically, does
anyone have any links to decent documentation on using iTunes over
ScriptingBridge from ObjC?

Are you trying to generate MP3 or another format? If you want to
convert your AIFF into something that is not MP3 (AAC for example),
there is better way than using iTunes. Else, as OS X does not include
an MP3 converter (for legal issues), you will have to use iTunes (or
another third party library like LAME). -

OK.
I'have just tested, and it look like the scripting bridge expects an
NSURL when it want a file.
So -[iTunes convert:] works well with an array of NSURL, and it
returns an array of iTunesFileTrack corresponding to the encoded tracks. -
That works!! Thanks very much Jean-Daniel.
