From 551c675782dd4c4441f2c6a8a42380eb7f961616 Mon Sep 17 00:00:00 2001 From: Philipp Zabel Date: Fri, 7 Jul 2017 05:58:29 -0400 Subject: [PATCH] media: coda: align internal mpeg4 framebuffers to 16x16 macroblocks This fixes visual artifacts in the first macroblock row of encoded MPEG-4 video output caused by 8 additional lines of luma data leaking into the chroma planes of the internal reference framebuffers: the buffer size is rounded up to a multiple of 16x16 macroblock size, same as for the h.264 encoder.
