Hi, everybody! I've got a question concerning MPEG files. Is it
possible to extract each frame from an MPEG file in IDL? I mean the
reverse process of making an MPEG file. If an MPEG file is made of 100
frames, I wonder if it's possible to extract all those 100 frame
images. I heard that it's possible using external linking with other
non-IDL routines, but I'm not sure about it.

The other question is about file transfer via FTP or WWW. Is there a
good way of data exchange via FTP or WWW with IDL? I want to download
data from an FTP site or a Web site. Also I want to try to upload data
reversely. Actually I used 'spawn' to activate FTP from DOS prompt. I
know it's one way, but I wonder if there's built-in capability of data
transfer in IDL itself.
