getting rid of ffmpeg-config

[Fabian Greffrath]

Hi all,

I have created a list of all packages, that build-depend on one of 
ffmpeg's library -dev packages. I have sorted and uniq'ed the list:

$ for i in `grep 'Package.*\-dev' debian/control | cut -d ' ' -f 2`; \
do grep-available -F Build-Depends -s Package $i \
/var/lib/apt/lists/ftp2.de.debian.org_debian_dists_unstable_main_source_Sources;\
done

alsa-plugins
aqualung
blender
cmus
ffmpeg2theora
ffmpeg-php
freej
gnash
gnusound
gstreamer0.10-ffmpeg
idjc
k3b
kino
ktoon
libavg
libquicktime
linphone
lynkeos.app
mediatomb
mlt
moc
motion
mt-daapd
opencv
openmovieeditor
picard
potamus
smilutils
sox
swfdec0.6
synfig
vlc
wengophone
xine-lib
xmms2


I downloaded all these source packages and grepped through the sources 
to find all references to ffmpeg-config:

$ grep -ir 'ffmpeg-config' *

$(shell ffmpeg-config --prefix)

vlc-0.8.6.e/configure.ac:dnl kludge because only the debian package 
provides a ffmpeg-config
vlc-0.8.6.e/configure.ac:dnl we try to find ffmpeg using : 1- given 
tree 2- ffmpeg-config, 3- pkg-config
vlc-0.8.6.e/configure.ac:dnl Look for a ffmpeg-config (we are on debian )
vlc-0.8.6.e/configure.ac:  AC_ARG_WITH(ffmpeg-config-path,
vlc-0.8.6.e/configure.ac:    [    --with-ffmpeg-config-path=PATH 
ffmpeg-config path (default search in \$PATH)],
vlc-0.8.6.e/configure.ac:  AC_PATH_PROG(FFMPEG_CONFIG, ffmpeg-config, 
no, ${FFMPEG_PATH})
vlc-0.8.6.e/doc/ChangeLog-2005:Add a test for pkg-config for ffmpeg. 
It now do in order: ffmpeg-config, pkg-config, default location, given 
tree. fixes #306.
vlc-0.8.6.e/doc/ChangeLog-2005:To cross-compile on a debian, use 
PKG_CONFIG_PATH=/usr/win32/lib/pkgconfig and 
--with-ffmpeg-config-path=somewhere with no ffmpeg-config 
(/usr/win32/bin by ex)
vlc-0.8.6.e/configure:    --with-ffmpeg-config-path=PATH ffmpeg-config 
path (default search in \$PATH)
vlc-0.8.6.e/configure:# Check whether --with-ffmpeg-config-path was given.
vlc-0.8.6.e/configure:  # Extract the first word of "ffmpeg-config", 
so it can be a program name with args.
vlc-0.8.6.e/configure:set dummy ffmpeg-config; ac_word=$2
xmms2-0.4DrKosmos/src/plugins/avcodec/wscript:    cfg.binary = 
'ffmpeg-config'
xmms2-0.4DrKosmos/src/plugins/avformat/wscript:    cfg.binary = 
'ffmpeg-config'


This means that blender, libavg, moc, motion, vlc and xmms2 the 
candidates to file bugs against.

Next question is: What should we do to finally get rid of ffmpeg-config?
- File bugs against these 6 packages?
- File bugs and provide patches for these 6 packages?
- Send a message to debian-devel?
- Silently remove ffmpeg-config?

Patches should be trivial and since ffmpeg-config is Debian-specific 
anyway, most upstream sources should have allready switched to use 
pkg-config, anyway. What do you think?

Cheers,
Fabian
