[libcamera-devel] [PATCH v4 6/9] ipu3: Configure imgu1 when necessary
Harvey Yang

Tue Aug 2 12:29:40 CEST 2022
This patch configure and setup imgu1 when still capture and other
streams are enabled. If only still capture is enabled, imgu0 is still
being used with IPU3PipeModeVideo (i.e. VideoSnapshot) to ensure 3A is
working.
Still capture stream will be enabled in the following patches.
