Is it really needed?
>From a quick look it seems all those Requires aren't needed:

$ fgrep x264 $(rpm -ql libffmpeg-devel | fgrep .h)
/usr/include/libavcodec/avcodec.h:#define CODEC_FLAG2_MBTREE
0x00040000 ///< Use macroblock tree ratecontrol (x264 only)
/usr/include/libavcodec/avcodec.h:     * 8 (umh), 9 (iter), 10 (tesa)
[7, 8, 10 are x264 specific, 9 is snow specific]
$ fgrep speex $(rpm -ql libffmpeg-devel | fgrep .h)
$

The problem is that if it isn't really needed it's adding unneeded
dependencies which mean unneeded rebuilds in the OBS.
Right now a package which uses ffmpeg but doesn't use x264 will be
rebuilt with each x264 change.


P.S. devel package with unneeded Requires for othe devel packages
looks like a general problem in Packman, this is not the only one. If
the build power is a problem...
