# NOTE: don't send it to Th unless you resolve libraries (incl. sonames) conflict with ffmpeg
# libav is a fork of ffmpeg; as of Dec 2012 they are not 100% compatible
# (e.g. libav didn't drop some deprecated APIs); ffmpeg 1.0.x seems more powerful than libav 0.8.x.
#
# How to deal with ffmpeg/opencv chicken-egg problem:
#	1. make-request -r --without opencv ffmpeg.spec
#	2. make-request -r opencv.spec
#	3. bump release of ffmpeg.spec
#	4. make-request -r ffmpeg.spec
#
