source filter : Read from memory

[sdan...@gmail.com]

Hi,

Is there any free source filter that reads chuncks of avi files from memory with a callback method, instead from a file ? I need this for a protection scheme i design.

Anyway is there any resource (besides the microsoft web site) of how to create a source filter ?

Best Regards,

Ok I found the sample memfile in the async filters of the SDK platform very useful, but the main question of how to load chunks of data in the memory (not whole data at once) and read them respectively is still open !! Anyway can help on that ?

PS: The suggested solution might take in mind that I use also progress bar slider for the playback that the user can move anytime he wants.
