Hi there,

I need to "convert" a wav file into a mov file. It would be sufficient to put it into the mov container without compression for now.

What I'm using now is:

    FSSpec from,to;
    FSRef fref,tref;

// init fsspecs FSPathMakeRef ((UInt8 *)[meetingAudioFilePath fileSystemRepresentation],&tref, nil); FSGetCatalogInfo (&tref,kFSCatInfoNone,nil,nil,&to,nil);

FSPathMakeRef ((UInt8 *)[filename fileSystemRepresentation],&fref,nil); FSGetCatalogInfo (&fref,kFSCatInfoNone,nil,nil,&from,nil);

    // init QT
    EnterMovies();

    // convert the file into movie...
    OSErr err=ConvertFileToMovieFile (
        &from,
        &to,
        'TVOD',
        smSystemScript,
        nil,
        createMovieFileDeleteCurFile,
        0,
        (void *)-1, // display standard dialog
        0);

    NSLog(@"QT converter status: %d",err);

It converts a .mov file, so far so good. The problem is, it just embeds a link to the wav file into the mov, so it can be played locally, but does not really contain the wave data. This is not helpfull, because I need to transfer the file to a distant location.

Can someone point a documentation that describes a conversion process *simply* and especially *without* using the configuration windows, because this process has to be run in the background without user interaction.

Being able to select a compression for the imported audio data would be very nice, but is optional for now.

thanks & best regards,
  Lars
