From 0729bc86227f24aad8bfc735e36745605aa65abd Mon Sep 17 00:00:00 2001 From: Dave Stevenson Date: Mon, 1 Feb 2021 18:48:47 +0000 Subject: [PATCH] media/v4l2_m2m: In buffered mode run jobs if either port is streaming In order to get the intended behaviour of the stateful video decoder API where only the OUTPUT queue needs to be enabled and fed buffers in order to get the SOURCE_CHANGED event that configures the CAPTURE queue, we want the device to run should either queue be streaming.
