Webcam?

Andrew Nixon

Using putty to ssh into the omega so once i get a external power supply shoul be able to make a little stream wildlife camera (maybe for the sheep out the back if the wifi signal goes that far). Any suggestions, maybe just a cheap powerbank ? A solar thing would be good.

Boken Lin

@Andrew-Nixon You should definitely try a power bank. Mine was able to power the Omega itself for about a week. With a webcam it can probably power it for 2-3 days.

@Andrew-Nixon For what it's worth, I am powering my Omega from a 2000mAh lithium battery and only ever access the Omega standalone via Wi_Fi (i.e. no USB connection) and I get a few days from it

@Boken-Lin When you had a PS3 EyeToy running was it in YUI mode? After some reading, it looks like that is what it runs with. That would put more strain on the processor that one that outputs mjpeg.

Anyway, when I plug my PS3 EyeToy into my RasperryPi this is what dmesg shows:

[   72.073814] usb 1-1.3: new high-speed USB device number 8 using dwc_otg

Where did you get the mjpeg_streamer source from? github.com/jacksonliam/mjpg-streamer.git? It doesn't come on the PI and isn't in apt-get. Going to try to install it from there.

@Boken-Lin Here's what I get when I try to run the ov519 (ps2eyetoy) driver:
insmod /lib/modules/3.18.20/gspca_ov519.ko :

[  733.050000] gspca_ov519: Unknown symbol gspca_frame_add (err 0)
[  733.060000] gspca_ov519: Unknown symbol gspca_debug (err 0)

failed to insert /lib/modules/3.18.20/gspca_ov519.ko

and here is what I get when I try to ins mod the manually downloaded ov534 (ps3eye) drivers:

insmod /lib/modules/3.18.20/gspca_ov534.ko 
[  723.300000] gspca_ov534: Unknown symbol gspca_frame_add (err 0)

failed to insert /lib/modules/3.18.20/gspca_ov534.ko

My guess as to the issue: perhaps the previous firmware versions @ 3.18.20 did work, but the newer firmwares upgraded the kernels which might have broken the ps2/ps3 gspca drivers. . .

Can we have the gspca drivers for the ps2 and ps3 baked into the firmware? Those are cheap and ubiquitous enough to warrant it, I think

Chris Ward

@Theodore-Borromeo Off topic, but do you have a PS3 eye toy working on a RasPi? Motion kind of sucks - very jittery, and not what motion was designed for. Looking at trying to compile jpeg-streamer.

Theodore Borromeo

@Chris-Ward I don't have a raspi. I have an esp8266, a parallax propellor (never used) and this omega. Also waiting on C.H.I.P., though now I've heard that raspi zero is out. . . I'm really just trying to see what the cheapest way to get an opencv capable camera is. I really want a front facing ranging device with wireless streaming to my phone for my car.

Uwe Press

@Chris-Ward Just received my C270 today and it is working fine. Still struggling with my PS3 cam

Chris Ward

@Theodore-Borromeo I am working on a similar project. I have a van that I am trying to create a rear facing camera for, as I can't really see out the back. I had thought the RasPi would be camera, but now I am thinking the Omega, the C270, and a distance sensor at the back, and the RasPi with a screen at the front to view.

@Uwe-Press I am not sure the PS3 will be a great streaming camera on the Omega. I would love confirmation, but I can only seem to get the PS3 eye cam to be in YUV mode on my RasPi which uses more resources than I would like.

@Steve-Fister said:

Ok, question. I'd like to free up the USB port on the Omega by hard wiring the USB camera to the board. I'm assuming that connecting the camera to the pins for +2.8vout (red), Gnd (black), USB+ and USB- will work? The camera requires 5vdc input. Do I need a step-up converter?? Thanks...

Boken Lin

@Steve-Fister If you use the Expansion Dock there should already be a 5V pin. If you are using the Omega with the Mini Dock, then you will need a step-up converter. Remember that the Vin for the Omega is 3.3V, so don't connect the 5V Omega directly.

Webcam App is now available as part of the new 008 release of the firmware

Was this ever resolved, saw mention of Lazar looking into this but no results were ever posted.

hello guys
i'm trying to stream and after several problems this is the closest i could get to make something work :
alt text
any ideas ?

N.B: i created a folder called /usr/local/www/ but did not set any specific rights on it.
also when i use dmesg it seems the camera is recognized with some sort of workaround message:

[ 2782.743229] uvcvideo: Found UVC 1.00 device USB2.0 Camera (1e4e:0109)
[ 2782.760050] uvcvideo: UVC non compliance - GET_DEF(PROBE) not supported. Enabling workaround.
[ 2782.774970] input: USB2.0 Camera as /devices/platform/101c0000.ehci/usb1/1-1/1-1.3/1-1.3:1.0/input/input0

from what i understood this is a proof the cam is mounted on the system:
alt text

this message surprizes me cause i have EXACTELY the camera shown on the end of this article : http://h-wrt.com/en/doc/webcam

any toughts ?

frederic raducki

it finally worked for me !
Desperate i connected two Webcams at once on my usb hub, then "ls /dev/v*" was showing video0 and video1

my newest cheap camera bought in 2016 shows the following message :
"[ 12.590190] uvcvideo: Found UVC 1.00 device USB2.0 Camera (1e4e:0109)
[ 12.597938] uvcvideo: UVC non compliance - GET_DEF(PROBE) not supported. Enabling workaround.

LAST LINE :
[ 57.016115] uvcvideo: Failed to query (GET_DEF) UVC control 11 on unit 3: -32 (exp. 1).

a very old Logitech webcam i have for more than 8 years (Logitech QuickCam Pro 5000) seemed to show a positive message when i was activating the stream with mjpg_streamer (while the newest was saying : "Unable to set format: 1196444237 res: 640x480 / Init v4L2 failed !! exit fatal" )

i started the same command on video1 ... the message was warning me that it cannot stream cause camera 1 already uses the port
Then i hot-unpluged my newest camera and started the command again.
This time everything worked and when i entered into Webcam app on the Omega Dashboard i could see my camera live ! i t also worked by going to page http://192.168.3.1:8080/?action=stream

Something isn't working webcam wise, I can't get beyond the following errors reported by dmesg...

[ 7093.779850] do_page_fault(): sending SIGSEGV to mjpg_streamer for invalid write access to 76dbcd68
[ 7093.789006] epc = 772dcbc4 in libc.so[77266000+92000]
[ 7093.794181] ra = 772dcbb0 in libc.so[77266000+92000]
[ 7093.799318]

tried upgrading, removing and reinstalling mjpg-streamer, different cameras, lots of different startup options and installing the console webcam app. Always the same error.

currently using mjpg_streamer -i "input_uvc.so -d /dev/video0" -o "
output_http.so -w /www/webcam --port 8080"

but can't change the error

any thoughts???

Thanks

Jon.

What is the status of the kernel driver for PS3Eye on Omega2?

PS3Eye is not UVC compliant.

PS3Eye as you know outputs YUYV, not Mjpeg, so what kind of FPS can you get over Omega2 WiFi over a 10-15m distance, for Mjpeg video streaming at 640*480 frames?
PS3Eye has both a mic and speaker, so can we use V4L2 on Omega2 for both video and audio streams?
