From 1bb7db217d9000a8e5fe53d9df691884fe8014bf Mon Sep 17 00:00:00 2001 From: Ganesh Ajjanagadde Date: Sun, 29 Nov 2015 21:36:52 -0500 Subject: [PATCH] avutil/crc: avoid needless space wastage of hardcoded crc table There was no reason AFAIK for making AV_CRC_24_IEEE 12. This simply resulted in wasted space under --enable-hardcoded-tables: dynamic: 1318672 libavutil/libavutil.so.55 old : 1330680 libavutil/libavutil.so.55 new : 1326488 libavutil/libavutil.so.55 Minor version number is bumped, with ifdefry due to API breakage.
