Re: Exporting MP3 file using QT... What a doc!

Hmm, you didn't really miss anything.
This is exactly what getting into QT programming is like.
It takes a LONG time to understand what the heck is going on.
And no, the docs don't help much. There is no real why or how explained very well.

And in YOUR case, you will likely be out of luck, at least on Windows where AAC just won't work for you.
You can tell QT to export the movie. There is a high level API that will prompt the user to select the various codecs etc. They can select AAC for the sound portion. Unless of course I am forgetting something....

Hi all!

I'm sorry for what -I think- will a really stupid and simple question. I've
never used the QT API, but I need it for a Cocoa program I'm writing.

This application needs to import a MP3 file and then convert it to AAC file.
I guess using QT for that is the best way to do, but I didn't though it
would be so complex to get what I need from the API.

I'm importing a movie using NSMovie object. I can get the QTMovie from it
but I don't know what to do with it next. I'm lost in the various component,
API functions... I've tried to read the Quick Start and a lot of other docs,
but it seems dark to me. And, as I read them on, the docs appear far from
what I want to do.

Some examples:
- I try to understand how to save a movie in a file, I understand that it's
not what I want: I need my file to be a AAC and not a MooV file.
- I try to understand the exporters, but it's all about imaging, not sound.

I often feel like I'm going too deep in the API. I just want to use QT as a
hig-level tool. I don't need to know what a Atom is or how to handle the
movie data... It seems to me the doc lacks of abstraction.

Did I miss something? Do I really need to read 250 pages of doc and hundreds
of lines of code to do such a simple thing? Is there a place where to find
some high level doc or something like that?

Sorry for being so critical, but I'm getting lost in here... Help!
