[Ffmpeg-devel] Decoding from blocks

[Emanuele Fumagalli]

Hi all, 

I'm new to FFMpeg and I've just built it on my pc.

Now I'd like to know how to use the libs to display a video that I'm getting get block by block, I mean I'm downloading blocks of the video in p2p and I'd like to decode and display while downloading. 
I'm having difficulties in finding examples about that, should I use av_open_input_stream? 
Has someone some idea? 
thanks in advance for any tips on that 

bye
