--- Comment #9 from Nicolas Dufresne (ndufresne) <nicolas at ndufresne.ca> ---
I'm actually on the wrong track. I've tested manually increasing latency in
720, 1080, and 2160p, and found out that it's not exactly one frame. The bigger
the resolution, the higher the latency. So this is in fact processing latency.
On my laptop, processing a 1080p jpeg takes about 33ms, a 720p buffer a little
less, so it was really luck that it worked.
