From bd36f175ab902fb6f1554ca3b4d9181228d628a3 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Reimar=20D=C3=B6ffinger?= Date: Sat, 14 Mar 2009 20:50:54 +0000 Subject: [PATCH] Make pcm_read_seek treat negative time stamps as 0, this avoids incorrectly seeking before data_offset and is more consistent with how the generic index seeking code handles it.
