From eda3758c87dafe8a6179b16e25e60b11746213ad Mon Sep 17 00:00:00 2001 From: Michael Niedermayer Date: Sat, 19 Nov 2011 20:37:42 +0100 Subject: [PATCH] ac3dec: update checked AV_EF flags. A user who wishes to use default error concealment cannot set the AV_EF_CRCCHECK flag because not every CRC in every format is a reliable indicator of bitstream damage. In some formats crcrs can be nonsensical in absence of any damage. We thus add the AV_EF_CAREFUL flag in addition to the AV_EF_CRCCHECK flag to allow a user to enable this reliable CRC check without having to enable all CRC checks in all formats.
