From de04408fd12d5d3b9fb3724034666a84cccbf190 Mon Sep 17 00:00:00 2001 From: Alexandre Courbot Date: Wed, 21 Oct 2020 02:09:43 +0200 Subject: [PATCH] media: venus: vdec: return parsed crop information from stream Per the stateful codec specification, VIDIOC_G_SELECTION with a target of V4L2_SEL_TGT_COMPOSE is supposed to return the crop area of capture buffers containing the decoded frame. Until now the driver did not get that information from the firmware and just returned the dimensions of CAPTURE buffers. The firmware unfortunately does not always provide the crop information from the stream ; also make sure to detect when that happens and fallback to providing the coded size in these cases.
