Request: Ability to capture specified frame

[DScorgie]

Hi,

One ability that would be really useful for me is to capture a specific frame within an app, rather than relying on a hitting F12. This is useful when debugging things like fixed frame timeloops.

I agree this would be useful, there's not too much detailed control over which swapchain or frame you capture at the moment.

In the meantime until I add this, have you tried triggering a capture from code? There's a snippet of C++ in the documentation you can use (under Tips & Tricks) that will trigger a frame capture starting from the next Present() on the active swapchain.

Gotchas to be aware of: 1) executing a deferred command list or 2) unmapping a resource you mapped a previous frame, will cause the frame capture to fail and the next frame will capture instead. Usually not a problem but it would be if you're aiming for a very specific frame :).

I've committed this feature in e289ffbb, you can choose to queue a frame capture before even launching the program, or afterwards in the connection window. This will be in v0.19.
