Subject: * modules/demux/real.c: re-order cook subpackets and send them 1 at a time to the... 
X-Git-Tag: 0.9.0-test0~12968
X-Git-Url: https://git.sesse.net/?a=commitdiff_plain;h=75f2ed950ec6f3b21b661cf0909a40fb8cc1dc0d;p=vlc

* modules/demux/real.c: re-order cook subpackets and send them 1 at a time to the decoder. This is required by the new ffmpeg cook codec (It also breaks our binary realaudio codec but I'll repair that later on).
