From 341064d68a134e2fb3dd35f8f5b50c6df8506c10 Mon Sep 17 00:00:00 2001 From: Gautam Ramakrishnan Date: Fri, 28 Aug 2020 00:15:36 +0530 Subject: [PATCH] libavcodec/jpeg2000: fix tag tree reset The implementation of the tag tree did not set the correct reset value for the encoder. This lead to inefficent tag tree being encoded. This patch fixes the implementation of the ff_tag_tree_zero() function.
