Hi I am new to QT and relatively new to mac programming.
I want to get pixel level data from wacked tv copy it into a data
structure of my own.
Reading through wacked TV in the SGVideo.mm section it appears that I
need to specify the k32ARGBPixelFormat somehow.
I think I understand what the pixelBufferAttribs is doing in that its
basically a structure made like NSMutableDictionary for the purpose of
collecting data to be used in IDCMDecompressSessionCreate which I
assume is where the image decompress occurs.
I have failed so far to find a clear description of how to format this
structure ie. what all the options are.
I am looking to get all the natural resolution and am unsure if the
height or width being determined by QT will affect that.
I am assuming that I want to make my copy just prior to
"
[pixelBufferAttribs release];
ICMDecompressionSessionOptionsRelease(sessionOptions);
"
I have the two QT books but they are pre cocoa. I have two cocoa
books but they are pre QT7. I have looked online at apple developers
but the links are not super easy to follow and often are not clear as
to wether they do or do not apply to the wackedtv generation of QT
commands.
If anyone can help me with any of the following it would be greatly helpful.
1) A guide to this type of thing, book, website, blog, message threads.
or
2) A site with a lot of QT sample code
or
3) The lines of code I am missing so I can get back to image
recognition and leave the QT stuff for now.
or
4) Tell me that the information in the QT books is still relevant or
that the guides from apple since such and such a date are applicable
etc.
Sorry to be so clueless but the combination of objective C and QT are
a little much for this casual C programmer to grasp all at once...
=)
