[FFmpeg-user] what will be the format of the buffer for AVFormatContext??

[Antonio Tsai]

Dear Experts,

There is a elementary stream which will be stored in a buffer and then
coded by "flv_write_packet(AVFormatContext *s, AVPacket *pkt)". My question
is what will be the format of the very buffer to fit to the sturct of
AVFormatContext, or how should I create a buffer for it. Could anyone
please give a some advice for it.

Thank you very much.
Antonio
