I'm interested in learning just enough Flash/Flex to do things that I can't do from HTML and JavaScript alone - play sound files and video, use multiple file upload things, perform cross-domain Ajax requests using the crossdomain.xml file etc. As such, I don't really want to learn (or pay for) the Flex IDE. I'm not much of an IDE guy in any case.
The problem is, most of the tutorials I've found talk about the IDE. I've figured out how to compile .mxml files at the command line using bin/mxmlc - now I just need to learn MXML, ActionScript and the various APIs! What are the best resources for learning these? I'm fine with buying a book, I just don't want to shell out for the API itself.
