Comment:
Well, if you specify a thread queue size of 1024, then if encoding can't
keep up with capturing then you eventually get 1024 uncompressed frames in
RAM meaning 1024*2560*1440*4 bytes which is roughly 14 GB. You either
should reduce the CPU load (use a faster preset, decrease resolution, etc)
or decrease frame_queue_size to a 10-20 frames if you accept a lower
framerate if encoding can't keep up.
