Subject: MPEG1 card
Can you help URGENT !!!!!
I need to use the Reel Magic MPEG1 PC decoder card in a slightly
unusual way. Instead of reading from a disk file I need to read data from
a stream that is being delivered over a network from a server; the
file structure on the server is not visible to me.
I have tried intercepting DOS interrupt 21h function 3fh (read from a
file handle) by using the C functions getvect() and setvect() so that I can
I can supply my data stream instead a stream from a file (I am assuming that
the Reel Magic software calls 'C' functions fopen(), fread() and fclose()
or something something similar to read the MPEG files from disk/CD)
but this does not appear to work; Windows ignores my overide of the
file interrupt 21 handler.
Can anyone give me any advice on how to accomplish the above or
perhaps suggest another way of doing it. I guess that ideally I
would like access to the buffers that the Reel Magic software allocates
to hold the data from the disk/CD.
Any suggestions appreciated.
