Hi,
I tried no setup uvc/mjpg-streamer in openwrt-kamikaze-7.09 as described here: http://naaa.de/programme/uvc_streamer/o … e-7.09.txt.
Hardware is a Netgear WGT634U (Broadcom 2.6, USB2.0).
But no luck. All packages installed without any problems, but when I connect my webcam (Labtec webcam pro, 0x046d/0x08a2) it gets recognized - but not as a v4l-device. I simply get a:

usb 1-1: new full speed USB device using ohci_hcd and address 5
usb 1-1: configuration #1 chosen from 1 choice

but thats all. No /dev/videoX is being created.

Any ideas? Any help? :-)

Best regards,
moh

I successfully tested a Logitech Quickcam Pro for Notebooks (2007) with Linux UVC and Kamikaze trunk.

I followed http://wiki.openwrt.org/webcam#head-594 … 8e75194ce6 and wrote that UCI configuration file and init script for uvc-streamer.

Thanks for your help.

But it seems that kmod-video-uvc is missing in kamikaze 7.09:

root@OpenWrt:/# ipkg install kmod-video-uvc
Nothing to be done
An error ocurred, return value: 4.
Collected errors:
Cannot find package kmod-video-uvc.
Check the spelling or perhaps run 'ipkg update'

<edit>
Sorry, didn't recognize that you wrote 'trunk', not 7.09. I'll check this out. Thanks again.
</edit>

Regards,
moh

Same Problem here,
your hardware isn't recognized through the driver
uvc_driver.c from svn linux-uvc missed a lot of idprod and idvendor

Moin Moin,
For Kamikaze 7.09 i published the backported linux-uvc driver at my site. This is also the reason why i wrote a "HowTo" (http://naaa.de/programme/uvc_streamer/o … e-7.09.txt). There were several changes between 7.09 and the current trunk version. I do not plan to maintain the kamikaze 7.09 and i will not prepare new releases for that version.

For the current Kamikaze-trunk there is no need to download the packages fro my site, you can simply compile them and they should work. Please verify if the ipkg install commands really retrieved files from the web or if that failed.

@moh_de: can you please post the output of "lsmod"?

Regards,
Tom

Edit:
Sorry, Mod_de, but your webcam is not supported by the Linux-UVC driver. It is supported by the gspca driver by Michel Xhaard. By now mjpg-streamer does not provide an input plugin to grab images from such a source.

I added experimental support for gspcav1 compatible webcams now. Many of those webcams also support JPEG compression by the webcam itself and should run well on a router. Perhaps you want to give it a try, so far my tests are limited to use the new input-plugin on PC (Ubuntu 6.06 LTS, Typhoon Webshot II, gspcav1-20071224) i did not changed the compile rule for OpenWrt yet.

Cheers,
Tom

Hi Tom,
I compiled r56 of mjpg-streamer and installed it on my wgt634u.

I'm using the spca5xxle module, because it fit my needs:

Hi Moh,
There is a new input-plugin "input_gspcav1.so". This must get copied to the target ("/usr/lib", or "/lib") and specified at the command line:
# mjpg_streamer --input "input_gspcav1.so --device /dev/video0" --output "output_http.so -w /webcam_www"

The compile rule does not necessarily need to get changed, copying the plugin across will be sufficent for the time beeing. The idea with the plugin-files (*.so) allows to save space at the target:
If you do not need the input_testpicture.so or input_uvc.so input plugins at all, you can save space by not copying them to the target. The same is true for the output_file.so plugin. If you just need a HTTP dameon output you can leave out/delete the output_file.so plugin.

Currently the picture controls are not implemented, framerate/hue/brightness/saturation etc. can not be set to another value, this will come later.

Regards,
Tom

Good news!

I still want to improve this plugin, so settings like saturation/contrast/framerate can be adjusted, but unfortunately this may take a while.

Greetings,
Tom

Hi Tom. I would like to test your mjpg-streamer too but my webcam is also only supported by gspca driver. Could you please update the trunk of openwrt to your new Revision (56)? The revision 51 now in the trunk does not support the gspa driver. Or could you explain to me. How do I compile your Revison 56 for my Asus wl-500gP?  I just know how to check out your patches with "svn co https://mjpg-streamer.svn.sourceforge.n … g-streamer mjpg-streamer", but what do I have do to compile it for Broadcom bcm947xx 2.6?

(Last edited by Oconnor on 12 Feb 2008, 00:32)

Hi,
You can simply checkout the mjpg-streamer sources from subversion with the similar command to the one you already know:
# svn co https://mjpg-streamer.svn.sourceforge.n … g-streamer mjpg-streamer

then you can compress it to be a tarball:
# tar czvf mjpg_streamer_rev56.tgz --exclude .svn mjpg-streamer

Copy this tarball to the folder where OpenWrt stores downloaded files. It is the subfolder "dl" and should already include many tar.gz, tar.bz2 and tgz files:
# WRT_FOLDER="/path/to/OpenWrt"
# cp mjpg_streamer_rev56.tgz ${WRT_FOLDER}/dl/

Edit the mjpg-streamer Makefile to use revision 56 instead of 51. The md5sum is not of interest, because the file is already in the "dl" folder. You may also blank the md5sum field.
# vi ${WRT_FOLDER}/feeds/packages/multimedia/mjpg-streamer/Makefile

Alternatively you can use sed (commands were not tested to work):
# cat ${WRT_FOLDER}/feeds/packages/multimedia/mjpg-streamer/Makefile | sed -e "s/PKG_VERSION:=rev51/PKG_VERSION:=rev56/g" -e "s/PKG_MD5SUM:=a9f26a96fdebdf3046ce920d2bcfb4ef/PKG_MD5SUM:=/g" > ${WRT_FOLDER}/feeds/packages/multimedia/mjpg-streamer/Makefile.new
# if [ $? -eq 0 ]; then rm ${WRT_FOLDER}/feeds/packages/multimedia/mjpg-streamer/Makefile; mv ${WRT_FOLDER}/feeds/packages/multimedia/mjpg-streamer/Makefile.new ${WRT_FOLDER}/feeds/packages/multimedia/mjpg-streamer/Makefile; fi

Compile OpenWrt with mjpg-streamer selected:
# make V=99

Then you should get a new *.ipk package for mjpg_streamer revision 56 in the bin/packages subfolder.

You still need to copy the input_gspcav1.so plugin manually as described above, you can improve that in the Makefile too, so it will can get included. I do not want to release #56 because I want to add at least some controls for gspca like framerate, saturation, brightness etc. Consider this as the early start of gspca support (according to the principle publish early and often).

Hope that helps, please try to understand what you are doing, because the commands given were not tested!!!

Kind regards,
Tom

You can also directly checkout from a subversion repo in recent trunk versions. Take a look at the utils/lcd4linux/Makefile (line 11-20). Adapt it to multimedia/mjpg-streamer/Makefile. Then in the mjpg-streamer Makefile also add the gspca driver plugin into the install template right after line 41. Now also input_gspcav1.so gets packaged.

Time to recompile the package and update the package index with: make package/mjpg-streamer/{clean,compile} package/index

Have fun

@Tom:
It would be really cool if you could add a init script with a UCI configuration file. Look at uvc-streamer. I added an init script and UCI configuration file there.

@forum2006:
Yes, that would be a good idea, but currently I am a little bit clueless on how to respect the modular character of all imaginable/possible plugins. Perhaps we limit it to linux-uvc input and http output, then we will see how rules get improved over time... This would make it an easy-to-use uvc-streamer replacement, which would be at least a start. Well, i put it on my long-term agenda (means i want to do that, but unfortunately it may take a few weeks).

Hi, thanks for answering my questions. But I get following error

What I did was
# svn co https://mjpg-streamer.svn.sourceforge.n … g-streamer mjpg-streamer
# cd mjpg-streamer
# tar czvf mjpg_streamer_rev56.tgz --exclude .svn mjpg-streamer
# cp mjpg_streamer_rev56.tgz /home/oconnor/Desktop/trunk/dl/
Edit the mjpg-streamer Makefile changed line 12 "PKG_VERSION:=rev51" to "PKG_VERSION:=rev56"
# cd ../trunk
# make package/mjpg-streamer-clean
# make package/mjpg-streamer-compile

After you applied the patch with 'cd feeds/packages/multimedia/mjpg-streamer; patch -p0 < mjpg-streamer.diff' recompile the package with 'make package/mjpg-streamer/{clean,compile} package/index V=99'. Then reinstall the new ipk package on your router.

Check the contents of the new mjpg-streamer package (du -ah build_dir/armeb/mjpg-streamer-r56/ipkg/mjpg-streamer/usr/lib/):

20K     build_dir/armeb/mjpg-streamer-r56/ipkg/mjpg-streamer/usr/lib/output_http.so

Contains input_gspcav1.so now From now on if you like to compile a newer revision from mjpg-streamer subversion you just have to adjust PKG_REV and then recompile.

Thanks that did it :-)! Now I only have to test my webcam.

Great it is realy working !!!! Thanks Tom and forum2008!
If there are new revisions I will test them.

I tried uvc-streamer first and it would lock up after a few frames. Then I switched to mjpg-streamer from trunk, revision 74.

Here is the commandline:
mjpg_streamer --input "input_uvc.so --device /dev/video0" --output "output_http.so -w /webcam_www -p 8080"

Problem is, it crashes with segfault immediately:
MJPG Streamer Version.: 2.0
i: Using V4L2 device.: /dev/video0
i: Desired Resolution: 640 x 480 
i: Frames Per Second.: 5         
i: Format............: MJPEG
then nothing more... pause.... crash

Webcam is UVC Camera (046d:09a4), a Logitech QuickCam E3500. Kernel module (uvc) is of course loaded.

Any clues? Need more info?

Will this work with latest code in subversion? gspcav1 is not used any more right?

Hi, I need the input_gspcav1.so to use my PlayStation EYE as webcam. The device specs:
gspca_main: ov534-2.14.0 probing 1415:2000

Can somebody help me in order to compile this lib for tl-mr3020 and tl-wr1043?

thanks!

just do: opkg install kmod-video-gspca-ov534
