Hey all,
I'm back to working on the installation and have noticed an irritating bug in pix_buffer_write (I think).
Once and a while (about 15 times out of 600) the buffer gets messed up when it is saved, the top 113 pixels of the image get copied over with what looks like a bitmask from another part of the image. Sometimes its totally black and opaque, other times you can see it resembles other parts of the image.
I can't see any pattern to it, and it seems to quite infequently (as long as your not writing 100s of images as I am)
I uploaded some of the messed up frames at:
www.ekran.org/ben/research/pix_buffer_bug.tgz
I would really like this fixed so that I can depend on the images getting written into buffers properly after 1000s of frames.
I wish I could see a pattern as to when this happens, it does always happen If I'm writing a lot of frames, but I can't force the creation of one of these messed up frames.
Thanks b..
