From f179616ec7dab5ab0276657386e7c61d024d2169 Mon Sep 17 00:00:00 2001 From: Jacopo Mondi Date: Mon, 8 Mar 2021 17:03:14 +0100 Subject: android: camera_device: Fail template on no FPS range The camera supported FPS range is crucial to distinguish between capture templates for preview and video recording. If the pipeline handler did not specify an available FPS range by registering the controls::FrameDurations property so far the control was simply not added to the generated capture template. In order to prepare to generate templates for video recording which require a fixed FPS range, fail earlier in generating any template at all if the available FPS range is not provided by the Camera.
