Is there any way when using Guetzli as a library to insert checkpoints where one could check an early exit flag and abort the compression operation? Thanks.

At what points you do think early exits would make sense

I don't know anything about the algorithm(s) that Guetzli uses. What I'm asking is if there exist any natural "rounds" or such where a callback could be made and the callback could decide to free the resources associated with the operation.

Yes, guetzli is an iterative algorithm so earlier abort (with larger/less optimized result) is possible.

Thanks, pornel. Do you happen to have any pointers on how I might hook that in? Currently I am using a single call to guetzli::Process.

Look for stop_early variables in the code. You'll need to hook them up (or another variable in similar places) to whatever mechanism you want to use for stopping.
