[FFmpeg-devel] How to write frames in a memory buffer, instead of a file?

Hi to all,

I'm using ffmpeg to encode H263 and MPEG4 videos.

I take frames from a shared memory buffer, and encode them in a file, 
opening it with the url_fopen() function, and writing on it with 
av_write_frame() after the avcodec_encode_video() call.

As I' m streaming rtp packets with live555, I'd like to know if it's 
possible to store in a memory buffer the frame I would write on the file 
with the av_write_frame() function I use now.

And if it's possible, how do you do it? (which functions of the API do 
you use, and how?)

Thanks to you all,
