Hi,
I'm using Pd Extended 0.42.5 and for a series of reasons upgrading is not an option right now. I don't have a Mac but I need my patches to work on Mac OS and Windows. (I can test windows and linux)
I don't know if it has been fixed in later versions of GEM, but there's some dreadful bug somewhere in [pix_video], [pix_movement] or [pix_blob] or maybe somewhere else, that causes [pix_blob] to randomly output out-of-range values for x and y (negative values and values a lot greater than 1), both on Windows and Mac.
On Windows a workaround that works is to lower the webcam's frame rate AND resolution (I'm not 100% sure the framerate is needed, but the resolution certainly is). I can live (unhappy) with having to do it manually every time, and I can trigger the settings dialog to open by sending the "dialog format" message to [pix_video] (unfortunately the values are not saved)
THE PROBLEM is that on Mac OS, the settings dialog that open up with "dialog format" doesn't give any option to change the resolution. I can change the framerate (which is not enough for the workaround to work) but not the resolution.
The questions then are:
lower the webcam's resolution?
least with my hardware)
find it documented)
And if anybody has encountered a similar issues (pix_video+pix_movement+pix_blob = out of range values) I'd of course love to know how you have worked around it (or is it worked it around?)
Thanks in advance cheers m.
