hi Diego,

as you remember, some time ago (shortly before the release of etch :->
what perfect timing!) I was forced to  link mplayer to a shared
ffmpeg library; when that happened I immedetly tried all available
 ./configure  --enable-lib...
kind of flags, but the final linking always failed
(as you can see, some of those flags are still there in 
debian/rules) ; the patch 30link-system-ffmpeg.patch
was the only working solution I found.

Today I give it a try again (indeed, the Makefile was completely
changed after 1.0rc2); but it does not work; see attached diff and buildlog

don't ask me why ...I have had no time ever to investigate.

Any suggestion? maybe there is a bug somewhere in ./configure,
 not passing some needed parameters to the final linking?

a.

ps: BTW at the time of 1.0rc2, AFAICR there was no flag
  --disable-libswscale_so , so that was another reason
 why I needed a direct patch into the Makefile

ps2: Reinhard is better at those problems (he indeed
 prepared a package that did link and compile in short time)
