hi all,

Recently , i'm work for streaming play from a web,i want to play a audio file in the process of downloading. I write the file(audio) to a buffer using iweb, if i play the buffer from the beginning,it works well. But it has a problem, for example,i want to play the 100k-200k in the buffer, it can not create IMedia interface, because lack of header information.
how can i resolve this problem?
