Hi all ffmpeg-soc(a)mplayerhq.hu is unused since 2011 and the last mails in it are spam. Also future sponsoring programs like SOC will use ffmpeg-devel I thus suggest to delete ffmpeg-soc and will do so in a week or so, unless there are objections Thanks -- Michael GnuPG fingerprint: 9FF2128B147EF6730BADF133611EC787040B0FAB The real ebay dictionary, page 3 "Rare item" - "Common item with rare defect or maybe just a lie" "Professional" - "'Toy' made in china, not functional except as doorstop" "Experts will know" - "The seller hopes you are not an expert"
