Vdr 1.6 and softieee1394

Hi,
I would like to know if anyone had softieee1394 running with vdr 1.6, if yes how ?
Cause i can compile it (after modifying the include line in some files) but when i try to use it i get an unresolved symbol message:

vdr: ./PLUGINS/lib/libvdr-softieee1394.so.1.6.0: undefined symbol: _Z13av_read_frameP15AVFormatContextP8AVPacket

did anyone had the same problem? did u solve it ?
Thanks,
Arturo

P.S.: i already asked in the softdevice ML, but till now noone answered me.

I installed from source ffmpeg and tried several version, the only trial i haven't done yet is to compile ffmpeg statically cause ldd show that the file use libavcodec.so and in the file there is no symbol, but not sure if this solve the problem. In the next day i will try that too.
Thanks,
Arturo

Ok, even if i compile statically the ffmpeg library i get the same error.
So, if anyone has any suggestion, let me know
Thanks!
