[GEM-dev] Re: [PD] GEM Linux and video codecs

IOhannes and Günter, thanks for your fast answer, as usual.

This afternoon I'll try to recompile Gem with the advice of IOhannes. 
If it still doesn't work, I'll be glad to test your deb package 
Güenter. I'll keep you inform of my findings.

I would like to test the performance of FFMPEG in Gem before and if 
there's not a big difference I'll use FFMPEG. But if I didn't get 
satisfaction with FFMPEG, I will had the support for LibMPEG2 as it 
doesn't look to complicated to do.
