Same as 4th patch. Please fix it.
For lat and core architecture, just need to get output buffer for lat decode. For core hardware need to get lat's message and capture buffer. In order to let lat and core decode in parallel, need to set capture buffer buffered.
I think the description should be rephrased. I may misunderstand but something like the template: """ OUTPUT -> lat -> core -> CAPTURE. Lat and core can work in parallel. Sets capture buffer buffered to ... """
