Hello,
Since, GSOX is drawing into a close I though I post an other
update on my
progress.
First of all, I have added support for yuv and hsb color output with
different color depths by using the color transform functions.
I have looked into the flip controller, and the only function I
could find
in the Quicktime API that should be able to do this is
SGSetChannelMatrix(channel, matrix) [0]. However when I try to set
an mirror
matrix (a scale + translate matrix) it return an error that
indicates that
the transformation matrix isn't supported.
Here is the code sniped:
MatrixRecord matrix;
Fixed minusOne = Long2Fix(-1L);
Fixed PlusOne = Long2Fix(1L);
Fixed zero = Long2Fix(0L);
ScaleMatrix(matrix, fixed1, minusOne, 0, 0);
TranslateMatrix(matrix, Long2Fix(self->boundsRect.right), 0);
SGSetChannelMatrix(self->channel, &matrix);
You can find more context in the file src/camera_mac.m:133
Nirav, since you joined Apple, maybe you can ask the good people in
Cupertino, how they intended this to be done :P
In case there is no way that qt support this controller, should I
just
keep them out and use transform.flip instead?
I have been testing the camera games by nirav (bouncy bal,
pointillism,
reflectionrejection), pointillism runs very slow, about 2,5 frames
a second,
and the other don't display an image frame. I haven't found the
problem yet.
