Playing files from memory using DirectShow

Buxe

Hello there!

I use DirectShow to playback all audio files (esp. mp3). At first I render them using RenderFile(filename). This works great but if i want to replay a stopped file using

->Run();

it seems to take too much time, because the game halts for a short moment until the sound file starts again.

My question is, if there does exist a method to play files from memory passing a variable which contains the data or the entire file (e.g. a char pointer).

After I have rendered the file is its data copied into memory for further playback or does DirectShow reads the file again when replaying sounds?

I'd be really glad I somebody can help me out here!
Thx a lot,
Buxe.
