Starting out from scratch

  • Hello message board!

    I'm new to development to osx applications (I've been working on java
    based apps for quite some time though) and I'm a little overwhelmed.

    My goal is to write some sort of screen capture utility that saves
    what's going on (on the screen) as a movie file.

    This is mostly to record gaming action so I'm hoping to keep this
    pretty lightweight so it isn't such a drag on system resources.

    I could really use a pointer as to where to start.

    Thanks in advance!

    You've actually stumbled on a rather nasty unsolved problem. There
    are a number of APIs which can be used for screen capture, but none
    of them have currently been demonstrated to perform well enough for
    use to "record gaming action". The best existing product I know of is
    Ambrosia Software's Snapz Pro; however, my tests have shown that it
    *does not* perform quite well enough (on ordinary hardware) to
    capture OpenGL programs running at full-screen. Any solution with
    acceptable performance is likely to require OpenGL driver hooks,
    which you definitely don't want to get into as a first project.

    That's pretty ambitious for your first Cocoa project.

    A great place to start:

    Have you seen the FAQ that's mailed to the list periodically? It has
    a number of pointers and links to other resources. The latest copy to
    be posted is archived here:

    Sigh - replying to my own emails. Bad sign.

    It would be nice if that sig that gets added to every post had a link
    to the FAQ. Just a thought.
