This is a long shot, but I thought I would ask in case an API exists to do what I want. One of the roles of my code is to record video to disk as it is received from a camera. A magnetic hard disk can normally keep up with this, but if the user is also doing other things on the computer (e.g. long file copy in the Finder) then we are unable to keep up, and accumulate an ever-increasing backlog of frames waiting to be saved. This eventually leads to running out of memory, thrashing, and an unresponsive computer. Dropping frames is not an option. In this case, the computer is a dedicated workstation running my code, so it *is* correct for me to consider my code to be the number 1 priority on the computer.
What I am wondering is whether there is some way I can communicate this requirement, to cause other apps such as the finder to get disk access at lower priority. Or alternatively, a way that I can demand high priority temporarily, at times when I identify that we have accumulated a save backlog? I can see reasons why this is probably not possible, but I thought I’d ask if anyone has any suggestions that might be relevant here. Thanks for any suggestions Jonny. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
