I discovered something interesting, so I decided to write a little program to have a custom bitmap serve as the static visual in the empeg player.
It is attached to this post. it reads a .bin-file from Tony's logo-editor and replaces the empeg logo with the home-image from logoeditor.
Usage :

setvisual <player executable> <bitmap file>

Please backup your player executable (/empeg/bin/player) before applying...

NOTE: this will probably only work on the 1.01rc2 & 1.01 version of the player app. I don't know if there is a difference in MKI/MKII versions...
Anyway, setvisual will check the size of the executable to have an exact size, so it shouldn't update older versions...

A great idea Frank. Although based on your warnings I am a little nervous to try it. If anything goes wrong can I just reload the developer image and I am back to a working player ?

Yes, a reinstall of an Image will allways make your player workable again.
you could also make a backup of the original executable :

# rw
# cp /empeg/bin/player /empeg/bin/player.org
# ./setvisual /empeg/bin/player /tmp/image.bin
# ro

to restore the orginal executable :

# rw
# cp /empeg/bin/player.org /empeg/bin/player
# ro

Frank-
Thanks for the great tool! I asked for this Months ago!
However when I run the install I get

empeg:/drive0/downloads/statvis# ./setvisual /empeg/bin/player img.bin
Player executable incorrect size: Success

My player looks like this

empeg:/drive0/downloads/statvis# ls -l /empeg/bin/player
-rwxr-xr-x 1 0 0 1076516 Oct 4 13:35 /empeg/bin/player

I reinstalled the 1.01 developer image after getting this message for the first time.

What's wrong?

John

I probably got the 1.01-rc2 developer image installed. I read in a post that the 1.01 developer image didn't change at all, only the emplode software had minor fixes. They probably changed some header files and the resulting binary files differ... :(

I've written a new setvisual which also replaces the small startup-logo. read the readme.txt file at http://empeg.dyndns.org/empeg/setvisual
Source is included so you could change the file offsets and recompile. ( You can also mail me the player executable if the empeg guys don't mind ? )

I too have a MkI and have been unable to make it work. (1.01rc2 developer)


Frank, what is the size of your player binary? Mine is 1030608 bytes.

I'm guessing that the Mark1 player executable and the Mark2 player executable are different (duh), and since Frank's code-replacer only goes by file size, then that's the root of why you can't make it work on a Mark1.

An idea: Frank, if you based the replacement code on scanning for the sequence of image bytes within the player executable instead of placing the hack into specified offsets, then it would work for both Mk1 and Mk2 units, as well as future-proof the code for upcoming versions.

Good idea Tony. I also found the TuxMux bitmap BTW. I'll try to integrate some things in displayserver too. It would be cool to just upload some .bin files from your webbrowser to patch the executable and restart it.

I've got a new version of setvisual which will try to detect the correct offsets.
I also tries to update the Tux Much visual.
usage has changed; just run it and it will start asking questions eg:

empeg:/# rw
empeg:/# cp /empeg/bin/player /empeg/bin/player.org
empeg:/# cp /empeg/lib/primitives.bin /empeg/lib/primitives.bin.org
empeg:/# ./setvisual
found static visual bitmap at offset 862432; replace? [Y/N] y
bitmap filename : /tmp/static.bin
written static visual
found startup-logo bitmap at offset 866828; replace? [Y/N] y
bitmap filename : /tmp/startuplogo.bin
written startup-logo
found Tux Much bitmap at offset 400256; replace? [Y/N] y
bitmap filename : /tmp/tuxmuch.bin
written Tux Much image
empeg:/# ro

It now automatically updates the files /empeg/bin/player and /empeg/lib/primitives.bin
Only the home-image from the bin file is used. the image for the startup-logo is a smaller size : 52x16. Put it in the left-top corner.

gzipped tar file can be found here
Please let me know if this works on MKI and other releases...

ok man, i am a total newbie to my empeg, so go easy on me.

I can ftp to my empeg, telnet what?

If i have a static i set to it, what would i login as, how would i telent to it, i mean, i know how to telnet, but i don't have any idea what the login and pass would be, is there a generic preset from the assembly line>?

IO see you have displayserver as well, i am super interested in this also, for the fto-ing back to my computer in the event of a loss. In face, i screwed p with tag and rename, and i hosed al my tags, and it would help me to at least get the ones back that i have on the empeg already.

So bearing in mind i am a total newbie, can i bug you to write out some specific instructions on teh telnet process to the empeg, most specifically what you login ass. I am a novice with linux/unix, but know enough to navigate dirs and run progs, etc..

thanks for your time

First of all, you cannot telnet into a standard empeg. a command prompt will be available over serial. Here are some instructions to get you going...

step 0 : download setvisual.tgz from http://empeg.dyndns.org/empeg/setvisual. The attached version only works on one specific developer-image and doesn't modify the Tux much visual.
step 1 : Connect your empeg through serial to your PC
step 2 : power on your empeg.
step 3 : start emplode and install a developer image on your empeg ( see emplode help )
step 4 : stop emplode
step 5 : start hyperterm
step 6 : set hyperterm to 115200 baud, 8N1, no handshaking
step 7 : reboot your empeg. Boot messages should appear in hyperterm
step 8 : press 'q' in hyperterm a couple of times after the empeg has booted
step 9 : a shell-prompt should appear. type command 'rw' to mount the root fs readwrite
step 7 : choose transfer->send-file from hyperterm menu and send the setvisual-executable and .bin-files
step 8 : type command 'chmod +x setvisual'
step 9 : backup your original files :

empeg:/# cp /empeg/bin/player /empeg/bin/player.org
empeg:/# cp /empeg/lib/primitives.bin /empeg/lib/primitives.bin.org

step 10 : start setvisual :

empeg:/# ./setvisual
found static visual bitmap at offset 862432; replace? [Y/N] y
bitmap filename : /tmp/static.bin
written static visual
found startup-logo bitmap at offset 866828; replace? [Y/N] y
bitmap filename : /tmp/startuplogo.bin
written startup-logo
found Tux Much bitmap at offset 400256; replace? [Y/N] y
bitmap filename : /tmp/tuxmuch.bin
written Tux Much image
empeg:/#

step 11 : mount the root filesystem readonly :

empeg:/# ro

step 12 : reboot your empeg
step 13 : enjoy your new visuals...

To restore the original files :

empeg:/# rw
empeg:/# cp /empeg/bin/player.org /empeg/bin/player
empeg:/# cp /empeg/lib/primitives.bin.org /empeg/lib/primitives.bin

oh sorry one other thing, the .bin files are the static image, i am not familiar with that format, is that something paint/photoshop can handle?

Well, you could send me your latest single... I assume you really are a rockstar...

I know, I must be berzerk, but I am not the only one...
look at the links sections of the unofficial developers-site and geek-site for other 3rd-party stuff...

You can find the correct offset for the image used in the TuxMuch visual by scanning the primitives.bin file for: int 128 followed by int 32 (both 32 bit unsigned words)

Make sure you only replace the first instance of this, or you'll end up with a very strange looking Anna Vu!

Note that in v1.1 this will not be necessary as the image is loaded at runtime.

Does that mean that we can change the 'faceplate' behind
the 'needles' on Anna Vu?

OK... I don't use them much myself as I find them too
annoying. But they can be handy when you want to read
(or allow others to read) what's playing from a distance -
for instance at a party.

Most of the people I've shown the empeg has liked though...

No - you can have a go, but you'd have to be a masterhacker. For a start the fonts are run-length encoded (6 bits count/2 bits data). Secondly in v1.01 the fonts are defined by two data blocks. One is effectively a header detailing character offsets and width/height data, the second contains the rle data.

Load primitives.bin into your favourite text editor and skip to the end of the file for some useful info.

v1.1 will see the birth of a new approach to font handling - you'll have to wait and see.

Have a go - correct positioning is most important. You might want to extract the original image to work out which pixels (off the bottom of the image) the needles rotate around.

If anyone comes up with a good alternative I might be convinced to include it in v1.1

I used Midnight Commander to scan the file, and could detect some characters by eye.
I found the Tux Much visual by poking at random places and restarting the player...
I wish I had seen the data at the end of the file sooner (ASCII view in midnight commander doesn't show it?), it would have been much easier...
I certainly do not want to modify the fonts though. As you said, it would be an immense work to complete...

Cool, I'm on it.

Frank, do you have a way of extracting the binary data of the original image and sending it to me? I don't know how to do that right now.

No, as far as I know, that visual will be available when 1.1 is released.
