From f06c344bd5cfc3ae1492b73a82b1d4050bec06fc Mon Sep 17 00:00:00 2001 From: Milan Zamazal Date: Fri, 27 Sep 2024 15:46:13 +0200 Subject: libcamera: software_isp: Track and pass frame ids A previous preparation patch implemented passing frame ids to stats processing but without actual meaningful frame id value passed there. This patch extends that by actually providing the frame id and passing it through to the stats processor. The frame id is taken from the request sequence number, the same as in hardware pipelines.
