From 669ccf19ed2059b9d517664a2dbbf6bde87e1414 Mon Sep 17 00:00:00 2001 From: Ezequiel Garcia Date: Mon, 27 Jul 2020 19:05:38 +0200 Subject: [PATCH] media: hantro: postproc: Fix motion vector space allocation When the post-processor is enabled, the driver allocates "shadow buffers" which are used for the decoder core, and exposes the post-processed buffers to userspace. For this reason, extra motion vector space has to be allocated on the shadow buffers, which the driver wasn't doing. Fix it. This fix should address artifacts on high profile bitstreams.
