Compiling driver for webcam

[max2950]

First of all very big thanks to all of you spending time writing custom firmwares !

I was wondering if it is possible to implement some kind of MPEG4 encoder in the WL500g... But i think that the routers CPU might be a little bit weak for doing this...
What would be great is a feature to specify the compression level of the outputed JPEG picture...

I also would like to port the ActiveX component for viewing the webcam to a java applet. Since i do not have enough free time to do reverse engineering i just wanted to ask if someone knows where to find the source code of this ActiveX component?

Best Regards....


hi again !
I tried to do some packet sniffing on port 7777... But i could not figure out how the image data is organized within the stream. I thought the JPEG images were just putted one after each other on the network, but i was wrong... Any ideas?

In fact, this router should be de-microsoftized. And replacing that ActiveX control for a Java Applet is really needed.
But I don't think there is a need to study the ActiveX control. There is an interesting project called webcam_server that can be used as a replacement for the ActiveX control used by Asus:
http://webcamserver.sourceforge.net/

[oCe]

I'd really like a compression-option for the webcam indeed (with my 64KB/sec upload I can get about 1 frame per 1.5-2 seconds...), but MPEG-4 is a bit overdone I guess; just some motionJPEG or any other decent but 'light' (in terms of cpu power that is needed) would be preferred (or required). and a java instead of active-x client would be even better! I'm no java and/or firmware-coder, so can't help with that; but can help with testing, where needed.

Hi!

Another webcam idea, if anyone have the time and interest to implement it: Encryption of the pictures so that only "authorized" people would be able to see them properly. If a Java applet is used, it could probably ask for a key, and use it to decrypt the images before showing them. I don't know, but I wouldn't be surprised if Java has standard libraries for doing DES encryption/decryption. I don't know if real time DES encryption would be to processor intensive for the Wl-500g box.

does anyone have an idea of what the output is that is send through port 7777 and might there be any media players for it?

I'm getting sick of this active X component

find a client that is capable of receiving data from the program RCAMD, i don't know if this is some standard stream or something...

Hi

http://mxhaard.free.fr/camera.html
Oleg, can you squeeze the Patch (http://mxhaard.free.fr/download.html) into the Kernel, maybe for .5 Release ?
I Want to buy a very cheap webcam with this Chipset :).

[Oleg]

Probably I can patch the kernel, have not tried yet, but it's not enough to make it work. It's also needed to adjust web iface, scripts and perform testing. I've no such device, so I can't do this.

[Arobs45]

Dear all,

Do you think sometime additional webcam drivers could be added or implemented in the firmware ?

As i am a total Linux n00b, what can I do if I have the webcam linux driver ?

Thx

JF

[WlanMan]

Hi

You would have to compile the desired camera drivers as a module for the mipsel kernel, in some way. I think this needs some more intensive tweaking of the configure scripts of the drivers or there integration into the kernel source tree of the development system. i tryed to do this with the Drivers for some ultra-lowcost sunplus chipsets, but endet up seeing the driver supported the cam only very ugly (incorrect shutter controll). You may check first on a normal linux box that the driver works well with the cam...

You could give this a try (http://wl500g.info/showthread.php?t=1864) ;)

[smarechal]

Hi,

I'll try to speak well english,

Is camsource a software that can be implemented in wl500 with java applet of camserv?

I 've got a webcam server running with this configuration. It work fine and you can also send capture of webcam by ftp.

If you want to see the result: http://www.webnature.net/?page=webcam

Have a good night

Hi

This is probably for Oleg...

I have a Creative NX Pro webcam. This one dosnt work with the WL500gx router, but it DOES work in my linux, with theese drivers :
http://mxhaard.free.fr/download.html

I cant make it work on the router, since the kernel source is not included in your firmware...and I dont know much about howto patch the kernel other than doing normal module compiles and so on....

Any chance that it can be included ?

It would add support for some 130 webcams....

[Oleg]

Kernel sources ARE included to the ASUS GPL tarball, my sources contains all required patches for making custom firmware.

[macsat]

But will it be possible to compile a module to load, or does the kernel here not support modules?

[WlanMan]

Hi

Olegs tarrball is a patch to to the original asus tarball, this one carys crosscompiler toolchain and the stuff youre missing. The SPCA driver is not stable on mips, you can try it by searching he forum for it. It seems to have a memory leak, it eats up your memory until kernel gets panic and starts killing processes...
Does the NX cam works good on your linux box ? i have one of these ultra integrated spca webcams sold at around 12$ or so, and these are not well supported (Edit: OK, new drivers seem to habe better spca561 support, have to try again :)).

[macsat]

...on my linux box that is.

I havent yet tried to cross-compile for mipsel

[dom]

Hello,

I'm testing spca50x.o driver for webcam and it seem work fine with videodog and i will hope to compile myself.

I got sources from http://mxhaard.free.fr/download.html and i compiled them with cross compilation tools (already used to oleg's firmware with successful)
but in this case i have too many errors.

I would be very interested to get these sources of spca50x.o or if anybody has succeeds with http://mxhaard.free.fr/spca50x/Download/spca5xx-20060501.tar.gz
then if you can explain what have you patched.

[vampire]

Yep, I'll be real keen to test the latest (and perhaps final for 2.4 acording to the site) driver out too if someone manages to compile it, the last spca driver i got that worked with my webcam was var:57.02. Camera detected as "USB SPCA5XX camera found. Type Flexcam 100 (SPCA561A)" (a cheap $15 NZD camera) and it worked.

[macsat]

Hi

Did anyone successfully build theese drivers for Olegs firmware? :

http://linux-uvc.berlios.de/

[dyonisos]

Can you please help me with a step by step guide how to compile the pwc 10.0.12 webcam driver into Oleg 1927-7g FW?
Or, if available, could you please provide me with the compiled 10.0.12 pwc module for wl-500g Premium, so that I can use my Philips SPC900NC? Thanks!

[geezerpl]

I'd love too to know how to do it (and why Oleg won't implement the newest driver in his FW ?) ?
Many thanks !

[raas]

....... (and why Oleg won't implement the newest driver in his FW ?) ?
Many thanks !

Probably because there's limited amount of space in the flash memory to store all the goodies we want..

(The flash size of the chip where the firmware is stored is 4mb, Oleg has a 'hell-of-a-job' to put everything he needs into this space)

and why are some older FW from asus 7 meg?:confused:

[lly]

geezerpl, dyonisos

There is no step-by step guide, since that action assumes that you have some knowledge in writing/compiling/building C/C++ programs.

First of all, you have to read this:
Recompiling firmware (http://wiki.wl500g.info/index.php/compilingcustomfirmware)

After successful custom firmware build, you should try two choices:
1) apply patches on kernel and make modules.
2) modify Makefile from pwc-10.0.12-rc1.tar.bz2 for cross-compiling and make it

In all cases, it is possible that you see some compilation errors. IMHO nobody can give to you universal solution.

Since pwc-10.0.12 is not released for 2.4.20 kernel, I apologize that Oleg simply hasn't enough resources for it adaptation & tests.

[al37919]

in principle, there is also a toolchain for native compilation on the router using built in libraries: http://wl500g.info/showpost.php?p=75208&postcount=11

However, there is no howto.

Hello, I have problem with this driver on WL-500gP. (Oleg WL500gp-1.9.2.7-9)

insmode is done in post-boot - driver is registered, but webcam is not recognized.
Is something need to change in config (webinterface) ?

Can somebody help me ?

Hi, I want to connect my logitech quickcam express to the asus.
having found on the forum, I have to use spca5xx.o for this.
according to the site of mxhaard http://mxhaard.free.fr/spca5xx.html I have to use this driver for this.

I have placed spca5xx.o in the flash under /usr/local/modules/spca5xx.o
and I do a /usr/local/modules/spca5xx.o in the pre-boot file.
however, if I (un)plug the device, it does not get recognised.

what am I doing wrong here?
and, if this is solved, how to continue.?

TIA

[wirespot]

All I see in your log is the webcam being connected and disconnected.

You need to load the module, not run it:


insmod spcaxxx.o

[raas]

Hello wirespot, thanks for your reply,

that was a typo i did.. in the pre-boot I do a


insmod /usr/local/modules/spca5xx.o
(like you said)

however I doesn't seem to run,

After a reboot I issued

insmod /usr/local/modules/spca5xx.o
in an ssh session manually, it returns with a promt (if I do it again, there's a message it's already there)

After that I posted the output of dmesg
(after I first (un)plugged the camera several times)


could there be something wrong with the spca5xx.o?
I got it from http://www.wl500g.info/showthread.php?t=6734&highlight=spca5xx.o

Any ideas?

[raas]

Hi,

some changes, I still haven't figured out why it doesn't work with the pre-boot script (the file is executable), but when I run it by hand ('registering' the spca5xx.o)
the last lines of dmesg looks like this

as you can see the driver is registered, but the driver doesn't recognize the camera? do I need an other driver or ??? i don't get it.

[dyonisos]

Does the webcam work at all? Have you tried it on a different Linux and/or Windows system? The spca5xx driver you have should be working.

[raas]

hehe.. smart thinking, dyonisos,
I got the webcam from a friend.. it is used.. but it is supposed to work.
haven't tried it on an normal pc though, but will do this tonight.

Thanks for your suggestion.

Thanks for your suggestion.

quickcam pro 4000 is working for me, but I think it is using a different driver.
I think you need the pwc driver


insmod videodev
insmod pwc
insmod pwcx

is this working?:)

[raas]

dyonisis and wpte, thanks for your reply.

I've tried the webcam on my pc, but no luck,
The webcam didn't came with a box, so I had to retrieve model/driver through a number on the webcam: V/UAL-9 this pointed me in the direction that it is a quickcam express. the picuter of a quickcam express looks like my cam, So I suppose this is the cam..

DL'd and installed the drivers, but when I connect the webcam, the logitech software doesn't detect it.. That's strange.. it looks like the webcam isn't working, perhaps it's broken, but that's strange, 'cause this friend of mine used it, and put it away working.

However, If I don't get it to work on a pc, I don't think it will work on the asus (indeed dyonisis)...
Will fidle around with it to see if i can get it to work.

you probably need an old driver, they are not really downloadable on logitechs website anymore, but some google will help you out:)
I had it too with an old logitech one, doesnt work on the new drivers, but the old ones work perfectly:cool:

[Tamadite]

I have found the following page have the source code for the Logitech webcam I have.

http://qce-ga.sourceforge.net/

Will I get the webcam to work with router's web interface by just complying the drivers? In other words, is router's web interface directly connected to the already defined drivers or will it work as soon as the device get claimed by the driver?

(Why I do not try it? Because I want to avoid dedicating several hours to set up an WL-500gP compiling environment in vain)

[wpte]

(Why I do not try it? Because I want to avoid dedicating several hours to set up an WL-500gP compiling environment in vain)

not sure if it directly works...

and on the setup... including installing linux (like ubuntu) well... an hour or so for beginners:p
compiling is usually max. 30min depending on your pc :)

making things easier:
for software you need this:

build-essential
libncurses-dev
gawk
flex
bison
zlib-dev
subversion
build essential contains all the build software:)

also don't forget to sudo things when they don't work:D
you could also make /opt as your own so you don't need sudo-ing all the time:

sudo chown yourusername:root -R /opt

the rest is just follow the instructions on the wiki: http://code.google.com/p/wl500g/wiki/CompilingCustomFirmware :)

I manage to compile the driver targeting my x86 under Ubuntu but I can't get Makefile to compile for MIPSEL. There is no CC or CPP variable I can set as:

CC = mipsel-linux-gcc
CPP = mipsel-linux-gcc -E

This is the Makefile that comes with version 0.6.6-6 of the driver.


#
# Makefile for the qc-usb driver (based on Linux Philips USB Webcam driver)
#
# NOTE: This make file can serve as both an external Makefile (launched
# directly by the user), or as the sub-dir Makefile used by the kernel
# build system.

# If CONFIG_USB_QC isn't set, we'll assume the user want to build this driver has a module

ifndef CONFIG_USB_QC

any idea?

[lly]

This is the Makefile that comes with version 0.6.6-6 of the driver.

any idea?
Unfortunately, Makefile above, don't ready for cross-compiling. You have to rewrite some parts of it.

[Tamadite]

You have to rewrite some parts of it.

That's not an option for me right now since my knowledge on this matter is quite limited.

If the Makefile is not ready for cross-compiling, will I get it to work if I try to compile it directly on the router?

You need the kernel headers for that I believe... so that will also be a bit problematic.
furthermore the driver will be compiled with the optware uclibc, which is older than the firmware uclibc. so that might cause trouble as well when you want to use it:(

If you want driver for "classic" Oleg FW 1.9.2.7-10, it compiled already - http://translate.google.com/translate?u=http%3A%2F%2Fwl500g.info%2Fshowpost.ph p%3Fp%3D119575%26postcount%3D46%26langid%3D3&sl=ru&tl=en&hl=&ie=UTF-8 (google autotranslate).

If you want to compile it for 1.9.2.7-d, you should:

build firmware from SVN first
setup proper LINUX_DIR
replace CC = mipsel-linux-gcc to CC = mipsel-linux-gcc-3.4.6


NB! Anyway, driver can be buggy

[kolaCZek]

Please,
can enyone built spca5xx driver for 1.9.2.7-d ?

[fukushimaku]

Hello,

I read from a lot of threads on different forums about
spca5xx but no results... I think I have 3 choices:

1st: compile the module onto router using actual compiler
2nd: cross-compilling the module on a pc machine
3rd: compile using same gcc version 3.2.3 with Broadcom
modifications from Asus directly to router

I attached here the makefile from 2nd and the result (spca5xx.o).


1st: I tried also to compile on the router the drivers:
http://mxhaard.free.fr/spca50x/Download/spca5xx-v4l1goodbye.tar.gz

- system: Broadcom BCM4704 chip rev 9 pkg 0;
- cpu: BCM3302 V0.6;
- Linux version 2.4.20 (gcc version 3.2.3 with Broadcom modifications) #109;
- firmware 1.9.2.7-10-USB-1.71 (from koppel.cz);
- webcam Logitech, Inc. QuickCam Communicate STX; ID: 046d:08d7;
- compiler: gcc version 4.1.1;
- linker: gnu ld version 2.17.50.0.8 20061201
(both installed with ipkg on /opt/ [compact flash, 16gb card])

At compilation process everything seems to stuck at /opt/include/asm/softirq.h
The output of `make` is:

-------------------------

2nd: I downloaded that version from the Asus's site
(and also the source of firmware: GPL_WL500GP_1.9.7.7.tar.gz and toolschain323.tar.gz),
extracted into pc#2 with CentOS 5.5, and configured in Makefile from spca5xx-v4l1goodbye.tar.gz
I compiled it after many struggles. Only few warnings and no error (see below):

Also there are few interesting results:
- on router, after /sbin/insmod videodev and
/sbin/insmod /opt/lib/webcam/spca5xx.o
there are no complains;
- some weird characters appear when the camera is loaded;
- appeared the message: `vlan1: dev_set_allmulti(master, 1)`;
- no video0 in /dev (nor /dev/4l/video0);
- no other errors, no tained, no unresolved symbols;
- there are no files in /proc/video nor /proc/spca50x
and some informations in files from /proc/bus/usb (see attached);

3rd: very slow (you know already the deal with the router's limited cpu, ram)...
so: no problem at `configure`, errors at `make`... still working at it...
don't know if I will see it finaly and properly compiled :(

I really don't still want to get to 2.6.x kernel; after few months maybe.
I appreciate every single advice in this problem.
