From afdca81f8f6a33b491f56494c35983de97a2ebea Mon Sep 17 00:00:00 2001 From: rtognimp Date: Sat, 28 Aug 2004 00:46:05 +0000 Subject: EDL enhancement/fixes: *Some edl's code moved from mplayer.c to edl.c (mencoder will use the same functions) * slighty faster * removed MAX_EDL_ENTRIES limit (just reserve the memory we really need) * really treat edl_records as a linked list (coz it is) * edl now 'remembers' pending operations after a manual _seek_ * better way of handling Mute/Umute eliminates some nasty bugs when manual seeking (scrwed up mute/unmute order, no audio after seek, etc) * seeking while on -edl mode now _WORKS_ Patch by Reynaldo H.
