- !MPEG Frequently Asked Question list {8-b
-
-
- (1) How do I make it work?
-
- 1. Set your MPEG file to filetype &BF8 ("MPEG")
- 2. Double click on it (make sure !MPEG
- has been seen by the filer first).
-
- (2) Where do I get MPEG files from?
-
- Try the following FTP sites:
-
- s2k-ftp.cs.berkeley.edu (128.32.149.117)
- in the directory /pub/multimedia/mpeg
-
- phoenix.oulu.fi (130.231.240.17)
- in the directory /pub/mpeg
-
- Remember to ensure you are in 'binary'
- mode before downloading any files.
-
- (3) What about sound?
-
- Not supported I'm afraid.
- Neither are Interleaved video and audio streams.
-
- (4) Why isn't it faster?
-
- The MPEG file decoding and decompression is
- written in C. The DCT (Discrete Cosine Transform)
- compression method is pretty slow (have you tried
- decoding a JPEG file lately!). I have a few ideas
- for speeding it up and I intend to implement these
- eventually.
-
- (5) How does this affect Replay?
-
- It doesn't.
-
- I've used the same colour translation/dithering tables
- and methods as Replay (courtesy of Roger Wilson) but
- that's pretty much as far as it goes.
