From 4adad5a19ac85de69ced6b1d154344609ff4e493 Mon Sep 17 00:00:00 2001 From: Christophe Gisquet Date: Fri, 22 Aug 2014 09:31:45 +0000 Subject: [PATCH] wavpackenc: reset trailer info on block encoding In some cases, in particular if several blocks are needed because of the channel layout (e.g. 2.1), the information used to write the trailing bits terminating the sample data was not reset. This would cause potential desync on the decoder, although decoded samples were actually mostly fine.
