DVPEG 3.0l read.me file
-----------------------
This is an explanation of the function of the various programs that are
in the DVPEG ZIP archive.
Vidsetup.exe
------------
IF YOU HAVE A PARADISE VIDEO CARD RUN THIS PROGRAM BEFORE YOU RUN DVPEG
AND DO NOT RUN THE AUTODETECTION (type N).
The video setup program is the only way to edit the list of video modes
that DVPEG uses. This program allows you to change and save options that
DVPEG uses. These options can be changed in DVPEG but not saved. The
main purpose of this program is to test video modes and remove those that
do not work on your video card. Any video cards and modes that are in
the user list are shown in red.
Problems
--------
24 bit graphics
---------------
If the colors are not right look under F7 and change the RGB to BGR.
For cards that use the Tseng 4000 chips there are several 24 bit modes.
The Diamond Speed Star uses 2048 bytes/line while most others use 1920.
Try the various modes in vidsetup and only keep those that work.
Other graphics
--------------
*** If your moniter goes blank or the display is not stable when trying
to display a picture, hit ESC immediately and do not use that video mode.
If you find that the moniter does not display a stable picture in certain
video modes then use this program to delete them. Unfortunately the S/W
has no way to know what video mode works with your card. In some cases I
can not even identify the SVGA video card although DVPEG supports it. To
solve any video related problems you must use this program.
It is best if you start off with the manual for your video card. That
should tell you what works and what does not.
I am sorry that the vidsetup.exe program could not be made more easy to
use. Future versions of DVPEG will use much more extensive S/W to identify
the video card and detect its version number, amount of memory, etc and
avoid this whole problem.
VGA or 16 Color Graphics
------------------------
This is partially supported. It will work well for JPEGs but the
quality for GIF, Targa and PNM pictures is not the best.
*************************************************************************
Note: If your video card is not supported with DVPEG directly you may
be able to get it working with a "universal" VESA driver like the
univbe VESA driver. It supports more cards than DVPEG does and is
available at most major internet sites.
*************************************************************************
When the program starts up it will detect what type of video card you have
and automatically enter all of the modes for that card in the user list. You
should find the hi-lighted card on the right of the screen is the same as
the video card that is in your system. The list of modes is in the lower
right hand side of the screen. Hit enter twice and you will get to that
"window" (ESC will back you out).
If you have your video card manual, delete (delete key) any modes that are
not listed in your manual. If some modes that your card supports were not
entered into the list then arrow to the mode you want to add and hit INS.
You can also add custom modes, if you know a lot about your video card, with
the C key (poking thru the source code to DVPEG helps - ie the modes.h file).
To test a video mode, move to the card you want to test (up/down arrows) and
then hit <enter>. This will put you onto the upper right window where you can
pick from the list of video modes that that card may support. With the
up/down arrow move to the video mode that you want to test and hit space. You
should see a series of vertical bars that fade in color as they go from left
to right. If you can not see the bars or the image is junk then dvpeg will
not work with that mode.
When you find what card/mode combo's work with your system you can enter it
into the list by hitting <insert> when you are in the upper right mode menu.
To delete an item from the list hit enter until you get to the lower right
user list menu. With the up/down arrow move to the mode you want to delete
and hit <delete>.
<enter> will move you "deeper" into the menu's while <escape> will more you
back out. When you are at the video card menu and you hit <escape> you will
exit the video setup program.
At this point it will ask you if you want to save the information. If you
have correctly made a list of working modes for your system then hit <y> and
the file dvpeg.cfg will be created for dvpeg to use. It contains the list of
working modes and a few other things (future features).
I hope that this makes sense and you find it usable. This is the worst
part of my viewer and it will be improved in newer versions.
Advanced features
-----------------
Using the 'F' command you can set a color to fill the screen with (any
combination of red, green, blue). This is good for testing to see if a
newer video mode (15/16/24 bit) is properly supported.
dvpeg286.exe (the 286 viewer)
-----------------------------
This is a 286 version of dvpeg. It is slightly slower but otherwise identical
to the 386 version.
dvpeg.exe (the viewer)
----------------------
The first time this program is run it will look for the dvpeg.cfg file
(configuration file from vidsetup.exe). If it does not exist it will run
vidsetup. This can present a problem with some video cards.
F1: help (always check this as I update the program more than I do this file)
Advanced features
-----------------
You can save the tint, contrast, bright setting for automatic setting the
next time a file is loaded. Use E to view the file instead of ENTER,
adjust the tint, bright, contast to your liking and hit S to save them.
To delete the settings for the picture you are viewing hit D. These
settings are saved in the file dvpeg.vu
4DOS file descriptions should be read and printed after the file name
If the Titles are turned on the 4DOS description will be printed.
Selecting (toggling) Options
----------------------------
Generally one letter in each line will be in upper case. When that key
is hit the option will toggle or change.
file_selection screen
---------------------
You will always see subdirectors in the file listing and can move thru the
directory tree by hitting enter when over a subdirectory or .. which will
move you out one level.
arrow keys: move around on the list of files/directories/drives
Pg Up, Pg Dn: move up/down one screen full of files
Home: move to the top of the list of files
End: move to the end of the list of files
ESC: exit the program
Enter: view the file or
move into / outof the current directory
F1: help
F2: change drive - just type a single letter ie d
F3: change viewing defaults (dithering, show menu, smoothing ...)
F4: change mask - type in *.gif, *.jpg ... (max. of 5 masks)
F5: change sort order (ie by name, file size, date ...)
F6: type in a new directory
F7: change some less frequently used defaults
there is lots of stuff under this including:
- enable decoding to buffer for better slideshow
- show picture sizes on the file list screen
- show 4DOS file descriptions (instead of file name) on file list screen
- change width of the 4DOS file descriptions on the file list screen
- enabling 50 line text mode
- turning the beep on/off
- turning error messages on/off
- changing the slide show delay
- enabling the screen clear before draw (some video cards don't clear it)
- change file buffer size for speed or to reduce memory usage
- twiddle - this controls the video screen size picked if a picture is 640 * 481
DVPEG will not use the 640 * 480 but will go to 800 * 600. If twiddle > 1 then
the 640 * 480 screen is used - thing of it as a "slop" factor
- ......
space: select a file for slideshow viewing (turns filename red)
A: select all files for slide show
s: start slideshow
S: run slideshow in a continous loop (ESC exits current picture
