From 011a4668fb5e17026626b7abdfe86bccb2fdb743 Mon Sep 17 00:00:00 2001 From: Florian Sylvestre Date: Fri, 17 Jun 2022 11:23:11 +0200 Subject: pipeline: rkisp1: Support IPA tuning file Pass the path name of the YAML IPA tuning file to the IPA module. The file name is derived from the sensor name ("${sensor_name}.yaml"), with a fallback to "uncalibrated.yaml". The tuning file name can be manually overridden with the LIBCAMERA_RKISP1_TUNING_FILE environment variable.
