REALLY helpful. Many thanks Chris!
Great, thanks for watching!
I am so glad I found your video! It was driving me crazy searching all the posts and no one explaining it the way you have here! Thank you so much!
Thanks for watching! How can I help?
@@ChrisRiley I am so sorry, I forgot to delete that part. I had figured out it was cheap camera I bought that wasn't working.
@@bryancampbell4604 No problem! I'm glad you got it worked out
@@ChrisRiley You seem to know a lot about 3D printing. Is there a way for me to contact you directly? I don't like commenting back and forth on here.
Thanks Chris! You are my authority on anything Octo! You could not have do this video any better! Well, unless you actually stopped by my place and did the setup for me. Did I mention that I have beer? :)
Lol! Thanks for watching
Chris Happy new year to you and all Keep up you videos
Thanks, Happy New Year!
Thanks man !
Thank you!
I must have missed the implication of the note that camera configs don't listen so I never added the --http-listen lines to my camera configs. Now they are working. Thank you for showing what needs to be done to get multi cameras working.
Happy to help! Thanks for watching
Thank you so much .Lost of your video really help me a lot. best wish for you.
Thank you for watching!
Great video, as always. Followed your advice step by step. Couldn't get both cameras to work simultaneously. Checked permissions, both equal and full. Tried Format MJPEG Vs YUYV, no change. Options set to 0.0.0.0, both cameras show up, no problem. Lastly, changed Framerate to 5 Vs 15 and both work just fine simultaneously. So the net is that the data rate of the 1st was overrunning the server's ability to deal with 2 at a time. Best to you, Barry
Thank you! That is very interesting, I will have to see if I can reproduce what you saw.
for further clarification, I have an Rpi 4b 2G in an Argon M.2 case (no M.2 board), 32g SD, 7" HDMI touch screen in HDMI port 2, 2 USB A 4 port extenders on the USB3 ports with a Prusa Mini and Prusa Mk4 on 1 with two Nexigo 1080P cameras on the other, bluetooth USB in the USB 2 port. 3A p/s for Pi 4 and separate 2a p/s for HDMI screen. Pi desktop with piclone and chromium browser added.@@ChrisRiley
"One last time".... SMACK!
Great information here!
Thanks Chris!
If nothing else, this video taught me how to finally properly grep.
That's great! Thanks
Chris, great video, got it working with my RPI4 and Wyze camera with the webcam firmware. Now I'm trying to add the camera to Prusa Connect for my Mini+, but Octopi doesn't scan the QR code. Perhaps you can do a video for this too?
Thanks! Interesting, I have been meaning to look into the Wyze webcam firmware, I will see what I can figure out.
When I go to the wizard (my first time btw) it brings up something else
Huh, I wonder if the process has changed since I did this video.
Chris, thank you for your helpful explanations. I have a question though. The two cameras I have don't have serial numbers, and the only way to distinguish them is through the USB port locations. In this case, how can I apply the method you mentioned earlier?
It's very hard to. This setup doesn't do a good job and giving you options for that. The multi octo setup here gives you a few more options when using the script to find them for you. ua-cam.com/video/nDwW3eNxp2k/v-deo.html
Hi. In local work two camera, but out local red only work camera of port 8080. Port 8080 camera Raspberry pi v2 and port 8081 camrea USB C920.Thank you so much
Your firewall is probably blocking port 8081. Have you tried octoeverywhere for remote viewing?
I'm not finding a path to "side-grade" an existing Octopi install to the new camera-streamer version, Until someone comes out with a seamless way to do this, I'm going to hold off. Doing one printer wouldn't be a problem, but I have 5 printers all running their own Octopi/Octoprint instances.
I hear that, doing a lot of instances has always been a pain.
For anyone looking at this, I've found that the internal backup process in octoprint is actually the best feature of the entire software suite. Taking a backup the the octoprint instance, reinstalling Octopi on my Pi 4, and restoring the backup has fixed issue with me totally ruining my install with bad configuration changes.
Really good video and some very helpful comments i just cant get it to work. when i have both camera plugged in and look at /dev/v4l it shows to cameras but when I go to add the second camera in on sudo add-usb-camera only shows one there. Possible a power issue?
Thank you! I've been hearing this, octoprint changes quickly. I need to give this another try to see if I can recreate these issues, stay tuned.
Will it work on port 443 using https? 8080 isn't encrypted.
hey, thank you for the tutorial. But I am having a problem. I did all the same but I cannot
see the second cam. I only see the first one I plug in the Raspberry. I even try to change the option to (OPTION="--http-listen=0.0.0.0").
Can someone help me out?
1) I create a new image in my SD card using the new_stack as in the video. But before I was using the stable version
2) I added the 2 camera files and assigned different ports
3) even if I do ps -aux |grep camera I see both cameras working + I tried OPTION="--http-listen=0.0.0.0" and OPTION=--http-listen=0.0.0.0
4) but when I insert the AP address + port I don't see the image coming from the second cam I plug in, whatever it is. 8080 or 8081. It is like it is not listening to all the ports.
should I empty/format the sd card and do the configuration from scratch?
Do this command to confirm the config is correct and port 8080 and 8081 are listening. sudo netstat -tnlp
I have the c920 webcam, may I ask how do I adjust the focus on it? I downloaded the 4l2 utility but when I run the command "sudo v4l2-ctl --set-ctrl=focus_auto=0" it returned "unknown control 'focus_auto'"
Don't remember how I did this. See if this helps. ua-cam.com/video/6EWySOb5W8E/v-deo.html
I just got a mintion v2 for Christmas, and that is a lot simpler to setup and use then this. So my question would be why should one get get this over that?
The Mintion works great for a lot of things. If all you need to do is time lapse and some light control, it works great! If you want to get really crazy with automation or different plugins that do different things, octoprint is a great option.
Great walkthrough. However, I can't seem to get my second camera working. Did all the steps, including the http listen and still can't access the 8081 camera. 8080 is a PiCam, 8081 is USB. looks like the camera-streamer-usb service is failing to start. Any thoughts? FWIW, trying to power this whole thing with a POE Hat
Can you use them one at a time? That would rule out any power issues.
@@ChrisRiley Turned out it was a combination power and the specific libcamera i had. Got a newer libcamera and at poe+ hat; now it all works! beware the pi brand poe+ hat as there is not enough room to install a libcamera with it. it will work with 2 usb cameras though!
Thanks for this video! It really helped me out. I'm running two logitech C920s but I can only run them in 720p otherwise one will quit working, the server crashes for that camera. I'm wondering if there is a way to get full resolution and possibly framerate while running these cameras. I'm running a Pi4 8GB version and it seems to not even break a sweat while doing this so I'm confused as to what is going on.
That's interesting that it causes it to crash. I wonder if it's a bug in camera streamer. It might be worth posting an issue over on the camera streamer github.
Get a mini-pc or thin client. They are much cheaper and powerful than pis but need a little more work to set them up since you might not be able to just use the o to pi image.
I had octoprint running on an old laptop but switched to the Pi when the 4s came out. It just seems easier to keep up with updates by using the Pi. I don't understand why I'm having troubles. The USB bus should have plenty of capacity and the CPU pretty much idles while everything is running. Also plenty of ram (8GB). I switched to a powered USB hub thinking there was a power constraint but that didn't help.@@lucianoag999
I'm looking for other plug-in,. I'd love one that can show both cameras at the same time. Is this possible?
I don't know of any, but I'm sure it can be done. Start here, the forum has great info. community.octoprint.org/t/new-camera-streamer/52800/32?page=2
Do you know if there is a way to update a current Octoprint instance with the new camera stack without having to do a complete rebuild? I'm on 1.9.3 currently.
Camera stack is part of the OS. Octoprint will prompt for updates - there isn't one right now. OS can be updated like any Debian/RPi OS from the command line at any time. If you have something really old running Buster, you'll reflash to get onto Bullseye.
Thanks!
Very strange I’ve got the same version of octopi & octoprint but there’s no camera-streamer folder
Hmmm, very strange, not sure what would have happened.
Hi Chris, thank you for the new vid. I used your old vid to create multiple instances of octopi. The video feed and general speed of loading octoprint was quick at the beginning. But lately it seems very sluggish even when loading the software on the browser. The video feed is also grinded to a 1fps.
Have you seen this issue before? I've restarted pi, but it hasn't fixed it.
Have you swapped the SD card? I had issues with SD cards wearing out and causing speed issues.
@@MrKornnugget I haven't yet. I'll try that however the SD card is from a reputable brand and only been in use half a year!
@@emrage I personally have had Samsung and PNY memory card wear out in 3 months depending on how many re-writes they are doing. I don’t think micro SD were designed for re-writes. I have been moving them over to USB drives or HHD’s and they seem to be more robust.
👍🙂 Thanks!
Any guide on how to remove the old stack, and install a new without reinstalling everything?
The only issue I have with octoprint, is the camera support. and I dont want to reinstall it all if i can get the new stack.
Yeah, that would be really tough to do since it's part of Octopi, not sure there would be any option. You could do back and restore from the settings menu.
Followed along, and didn't work for me... i'm using libcam (pi camera module) and a USB camera.
I can get the lib cam working, but the usb camera isn't accessible via direct URL like you describe @00:21:34
It also doesn't work within octoprint's UI..
I'm going to go ahead an assume here the HAProxy you just casually glossed over is the issue here.
You shouldn't need to use haproxy to get this to work with this version. Of course you can if you like.
amazing video! i have some issues with octoprint can you help me please
How can I help?
Nice, but what is when I used multiple instances (octopi deploy thing)? I've OctoPi 0.18 with 2 printers and 2 cameras... it worked and now the golden rule: never change a running system.
Yes, things have changed for sure. In 0.18 we were hacking our way through to make it work. Now with Octopi, they are giving us more option to NOT do that. Still the easiest way to do the multi deploy is with Paul's script.
When attempting to connect to the second camera i only get a server error, does anyone know why that could be happening?
Make sure the permissions setting is correct in the config file, that's usually what causes this issue.
adding and removing and editing multiple cameras should be available within the octoprint camera plugin, ssh in the pi is unnecessary when there is such a powerful web app.
Thanks for the tip!
Chris I went to do update and PI Imager made me update it first to v1.8.4...How just all Pi images are right there...Thanks..
Great 👍
Is this really a "new" stack or the "new" stack released early last year?
I think this one has been available for awhile now. I have been using it for some time. I am not crazy about it. It works for USB cameras though I did have to restart the server once. It has issues though with raspberry pi cameras that use the camera connector. They start out working, but a few days later the stream no longer works. I will probably go back and try the legacy image with the old camera stack and see if that works better.
Yes, it's been out for a while.
i keep getting /boot/camera-streamer/': No such file or directory whenever I try to access it
Make sure you are choosing the correct image from the tool, there are 2 right now.
followed today tutorial until something happened. got 2 generic webcams (they are identical), i configured the first okey, but when i plug in the second, it doesnt show up on the webcam list to add it to port 8081. any solution to this? in the multiple deploy script it used udev rules to separate them, but since the script doesnt work with new versions for cameras im screwd
The cams might have the same serial numbers or no serial at all. When that happens I use Paul script to do my installs. ua-cam.com/video/nDwW3eNxp2k/v-deo.html It does a pretty good job identifying them and keeping them separate.
@@ChrisRiley yeah, i ised that script too.. but in the last update, if it detects you are using the new camera stack version it doesnt allow you to install cameras at all..
My cam urls work for both cams when i enter them on web but when i enter the urls into MultiCam they dont show.. edit: Now the cams only work 1 at time and switch between the 2 on every reboot
That is usually caused by there being most than one stream. Make sure you are using the device in the config that has the 0 at the end.
I have attempted 3 times going through you video. But my cameras are not working. I’m a newbie but I see my cameras in there config files. I have them in port 8080 and 8081. When I try to connect from the browser using ip address I get “the webcam server is currently not running “ I checked camera-streamer but it goes like three times and then stops. It doesn’t take me to my terminal again like it did for you. I had to control a to get back to my terminal. I have two old Logitech web cams
Sorry hit control q. Any help is appreciated thank you
If you do ps -aux |grep camera do you see the cameras running? Does it list the ports correctly?
No it did not show the cameras or the ports just “31095 0.0 0.0 7452 496. Pts/0. S+ 12:33 0:00 - -color=au to camera. I also think I may have under powered power adapter and should get a new one 3 amp adapter today. I noticed the lights come on for a second on the webcams and go out. When I plug into my windows computer the leds are on all the time. Thank you so much for taking the time to answer my question. You are very knowledgeable about these devices and have vastly improved my 3d printing. Saved a couple of prints already with your video on restoring prints from power losses. Thank again for your time and willingness to share your knowledge
most people using USB cameras will want to edit the usb-default and change the format from YUYV to MJPEG.
🙂👍
Does anyone know when octopi might be available for Raspberry Pi 5?
Getting a lot of questions on it and I am not sure, I will try to get a hold of one and test it out.
@@ChrisRiley hi Chris. I was able to get octoprint on the pi5 using octoprint_deploy. Module 3 camera still not working though. Been testing various methods but none that i can get working. I've also been able to get klipper running with the raspberry pi 5, flashed klipper on my ended3 v3se but again,cant get the module 3 camera wotking or any of my usb cameras.
When I try to access the second camera, I get a server error in the browser. Is there a solution?
I will have to go back and try thing again, things change a lot with the configs, there could be an issue.
@@ChrisRiley If I connect a second older webcam, it works.
But unfortunately not with the ones I want to work with.
It looks like the 2nd one is not getting any power.
Logitech C270
Trust Trino
Both work separately.
hi i like your video it seems you know a lot about the octopi or octoprint ad i was thinking about getting into it i do know how to print but im having some problems i had to repace the motherboard in my creality ender3 s1 plus because the sd card reader stop working and im not having much luck trying to figure out how to flash the firmware will octoprint help me flash the firmware im at the point im ready to throw it out the window all help would be great i have ask other ople and they dont give me the time of the day
Hello, thank you! Octoprint isn't going to help you much with flashing firmware. Most of that is done on the SD card now. Make sure you are using a smaller SD card, around 8gb, to flash the firmware. Also, make sure it's formatted FAT32.
@@ChrisRiley thank you for answering me
Good day Chris. I have a raspberry pi 5. Trying to get raspi camera module 3 and a ps3eye camera working. Please do a tutorial like this for the pi5 with a ps3eye or any usb camera. Please my guy
I'll look into it!
@@ChrisRiley Dude! You're legendary
It would be great if you mentioned the latest release is from October 2023, so while the "newest" not so much "new"
¯\_(ツ)_/¯
I miss my cameras/Octoprint, I went over to klipper a few weeks ago and i find crowsnest to be absolute garbage, 3 printers, only one camera works
Sorry to hear that, I could get 2 cameras to work, but I've never really used them very long.
Nah..Octoprint always felt like a bloated fossile. Once it was the only thing we had and it was good, but nowadays it looks like Octoprint stumbles far behind the other Printer OSes in a try to keep up but fails.
Thank you for your insight!
@@ChrisRileyI agree somewhat but for this use case the common chinese boards that they use to run klipper barely qualifies as an sbc as far as compute power to run any decent single camera. I suspect people with multiple of the shelf printers who want a good multicam solution will always choose a pi 4 b and use octo. I suspect pi5 adoption is going to be much lower due to the rp foundations catering to big business during the chip shortage. In Canada a 4 gig pi4 was 300 plus tax for the longest time. It's regular price is 150 though as I've never met a Canadian who got a full pi board for the 35 dollars I've always heard about. The pico w costs 25 here as a frame of reference. It's a great mcu but the debugging solution is complete ass. Plus I prefer modern c++ to interpreted languages. Python is fun for making crappy nes knock off games if you can't draw pixel art well haha
Chris, thank you for the informative video. I had set-up two C920 cameras and things were working great.. both cameras where working. Due to an issue with Raspberry Pi, I had to shutdown and disconnect the cables. When I restarted the Pi, my second camera doesn't work... when using the 192.168.58.37:8081/?action=stream command, I get Server Error. I did the sudo netstat -tnlp as you suggested in another comment and it shows that second camera on 0.0.0.0 port 8081. That config file has the http: command for 0.0.0.0. as you showed in the video. I have looked in the knowledge base but can't find an answer. Any thoughts?
Chris, here is something more strange. From print to print, the working camera will change from camera 1 to camera 2 or vice versa.
It sounds like it's confused on what stream to use. It should know which camera serial needs to be used for which camera. Unplug the cams, power down and bring it back up without them plugged in. See if you can get them to recognize the cameras again in the right order.
I have two of these cameras, but the second one is not shown up. usb-046d_C270_HD_WEBCAM_200901010001-video-index0
The C270 should have serial numbers. Can you see the camera directly from the URL in a browser? It could be the host setting I show. Look for 0.0.0.0 in the config.
hi Guys.
great video, now i got the cams working, but not both at same time, beacuse same id, vendor and so on.
tried with /by-path/ instead of /by-id/ but dont work.
any ideas ?
platform-fd500000.pcie-pci-0000:01:00.0-usb-0:1.4:1.0-video-index0
Thanks! The only thing I know to do here is add a devpath, it's not a great solution, but if you keep the cam plugged in the same USB ports, it can work.
@@ChrisRiley thats what I want, but how?
With my suggestion it didn't work. I will left in this port! That's the best solution, as the port is always the same.
