[libcamera-devel] question about Requests

[David Plowman]

Hi everyone

I've been updating my libcamera apps to use the new Request functions
(unique_ptrs and reuse), and I ended up re-inventing the same code as
has been put into qcam (lists of unique_ptrs, "free" Requests, another
mutex). I did find myself wondering whether this could be hidden in
libcamera.

For example, createRequest() gives you a raw pointer, but which
libcamera always owns. When a Request completes and you're done with
it, call reuse() and the next call to createRequest() is allowed to
give it back to you.

Possibly I don't understand the bigger picture here, it was just a thought!

Thanks
David
