hi guys
So I am pulling video off of an IP camera, encoding them into mpeg4 and writing 
them to a disk. Now I want to be able to see the video as I am writing them to 
file, therefore I want to be able to decode the packets that I have freshly 
encoded and feed them to SDL to be drawn to the screen. Now in order for me to 
decode video I need to have a AVCodecContext and usually if I am getting the 
video from the file I can generate a AVFormatContext and get the stream 
information using av_find_stream_info() and then grab the AVCodecContext that I 
need off of the AVFormatContext. But here, since I am not opening a file how 
can I get the AVCodecContext that I need? I tried to set the AVcodecContext to 
the same one that my encoder uses, but that didn't work. Any help would be 
appreciate. 

Xin Cai
