yes, but decoded from mpg2 stream will be seperate fields. And i look 
for the code where two fields will be build together to one (full 
sized) frame. But currently i can't find this code. Perhaps you can 
point me to this source? 
I've found DecodeMPEG2Video and avcodec_decode_video calls (libmpg2 and 
ffmpeg). The resulting AVFrame from this calls contains a complete 
frame (two combined fields), therefore inside this calls the combine 
should go, but where?
