hi, thanks for answering,
I'll try to be more accurate, basically I receive sequential packets (let's 
say 250kb) of data so my entire file(avi) come in blocks i.e (block1, block2 
I want to decode the file while still receiving blocks, so I start when I 
have at least 20s(so a certain number of blocks) and I'd like to decode and 
render on video the blocks I have without interruption.

Being at a first stage of my research I just be happy to know if this is 
possible using FFMPEG.

thanks again
