From: Oskar Arvidsson Date: Sun, 10 Apr 2011 20:42:36 +0000 (+0200) Subject: Choose h264 chroma dc dequant function dynamically. X-Git-Tag: v0.7b2~69 X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=e39e3abad4ce667f06d41097428695a7aad095fb;p=coroid%2Flibav_saccubus.git Choose h264 chroma dc dequant function dynamically. Needed for high bit depth h264 decoding. Signed-off-by: Ronald S.
