From 645838b51962e457250569d0fbe435d13792b93f Mon Sep 17 00:00:00 2001 From: Philipp Zabel Date: Thu, 7 Dec 2017 09:59:51 -0500 Subject: [PATCH] media: coda: use correct offset for mpeg4 decoder mvcol buffer The mvcol buffer needs to be placed behind the chroma plane(s) when decoding MPEG-4, same as for the h.264 decoder. Use the real offset with the required rounding.
