From 522f19e013904faa99380577804d5da992f30bd8 Mon Sep 17 00:00:00 2001 From: Nicolas Dufresne Date: Thu, 28 Apr 2022 09:19:57 -0400 Subject: [PATCH] v4l2videoenc: Setup crop rectangle if needed Hantro H1 and Rockchip VEPU2 drivers will pad the width/height to a multiple of 16. In order to obtain the right JPEG size, the image needs to be cropped using the S_SELECTION API. This support is added as best effort since older drivers may emulate this by looking at the capture queue width/height.
