[Libav-user] Initializiang an AVFormatContext structure from buffer

[francesco at bltitalia.com]

Hi to all
up to now all example I saw foresee reading a frame from file using
av_open_input_file whose first parameter is an AVFormatContext pointer that
will be initialized. If I have yet the data in a buffer, how can I initialize 
(or do the same job of av_open_input_file ) starting from a buffer ?
