From: Ronald S. Bultje Date: Sat, 13 Dec 2008 21:40:20 +0000 (+0000) Subject: Split RMContext into RMDemux/MuxContext and make them private in rmdec/enc.c. X-Git-Tag: v0.5~1681 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=1edddc99dc247166fe7ca3ad85346a237cbe72d4;p=platform%2Fupstream%2Flibav.git Split RMContext into RMDemux/MuxContext and make them private in rmdec/enc.c. Reason for this is that there are no shared entries in the demuxer/muxer context, making it a mystery as to why it was shared between the two. See "[PATCH] clean rmdemux/muxcontext" patch on mailinglist.
