Subject: [Buildroot] [PATCH V2] ffmpeg: enable use of freetype and fontconfig
Date: Mon, 26 Jan 2015 19:22:35 -0600 [thread overview]
Message-ID: <54C6E85B.2010707@ou.edu> (raw)
Configure ffmpeg to use freetype and fontconfig
if those packages are selected.
ffmpeg freetype support require fenv.h
which is not available in uClibc
except for uClibc on x86
Signed-off-by Stephen M. Kenton <skenton@ou.edu>

V2 Added fontconfig to make freetype support more robust
I could not find a good way to do "or" in the make file
Is there something better than nesting and using two
ffmpeg_environment_has_fenv ?= y
statements? I'm not really happy about the temporary
