Thanks now it compiles ...

But while loading asterisk i have another error:

[Nov 10 18:27:35] WARNING[32076]: loader.c:363 load_dynamic_module: 
Error loading module 'app_transcoder.so': 
/usr/lib/asterisk/modules/app_transcoder.so: undefined symbol: av_freep
[Nov 10 18:27:35] WARNING[32076]: loader.c:657 load_resource: Module 
'app_transcoder.so' could not be loaded.

av_freep() seems to have something to do with ffmpeg again ...

Big question: Is this an issue in app_transcode ? Or for ffmpeg ?

Thanks for your help so far ...

Regards,

Tobias
