Hi all,
I'm trying to use the Apple sample code at
http://developer.apple.com/qa/qa2001/qa1147.html.
I want to create a raw, uncompressed, AVI file using QuickTime from within
my app.
If I pass in kWindowsRawCodecType I get error -8961 (noCodecErr) back from
ConvertMovieToFile.
I did some experimentation and if I pass in kIndeo4CodecType (just like in
the sample code) I get the same error.
If, however, I pass in kCinepakCodecType, kJPEGCodecType or kBMPCodecType,
I'll get an AVI file (though the last two formats won't play in Windows
Media Player or Real Player on Windows--only with QuickTime Player).
I also went so far as to put together some code that calls
ConvertMovieToFile and brings up the export dialog so that I could manually
select AVI, None and Millions of colors and after the dialog is dismissed I
used QTGetAtomDataPtr to get the spatialSettings out of the codec in use and
confirmed that all of its fields are set to the same settings I am trying to
use.
I'd think that there is a bug in QT but QTPlayerPro can export an AVI just
like the one I'm trying to create programmatically. So the only thing I can
think of it there must be something else I need to do in the code to get
this to work.
In searching the QTTalk archives I see this issue came up a couple of years
ago but no one ever really posted a definitive answer (at least that I can
see).
Has anyone else been able to get this code to work or been able to create a
raw AVI file?
Thanks,
--ken
