Hi,
I'm currently trying to convert a sequence grabber based on the old
sgdataproc example to use the newer quartz/quicktime model. As there
currently does not seems to exist much conceptual documentation, i
have delve into it, head first. But already my first attempt to create
a CVPixelbuffer fails:
CVPixelBufferCreateWithBytes (NULL,
config.xsize,
config.ysize,
k32RGBAPixelFormat, //assuming I get this with a raw codec
in the sequence grabber, but since there is no length parameter, the
memory should be interpreted as such a buffer.
callBackData,
config.xsize * 4, // 8 bit *4
NULL, //no callback
NULL, //callback reference
NULL, //Pixelbuffer attributes
&pixelbuffer);
First question: Is this function the equivalent to NewGWorldFromPtr,
that I assume it to be ?
Second question: What the heck does the error code 6680 mean. It is
not listed in the CoreVideo result codes yet...
Third question: Do the parameters look reasonable to you ?
Fourth question: Is there example code I might have missed ?
Thanks,
Martin
