From cdc2c1c57616956d975c57b4b69eb73865f513f5 Mon Sep 17 00:00:00 2001 From: John Stebbins Date: Fri, 1 Jul 2011 08:57:42 -0700 Subject: [PATCH] matroskadec: matroska_read_seek after after EBML_STOP leads to failure. EBML_STOP leaves matroska->current_id set. Then matroska_read_seek changes the stream position without resetting current_id. The next matroska_parse_cluster fails due to calculation of incorrect pos. So clear current_id when avio_seek happens in matroska_read_seek. Signed-off-by: Ronald S.
