No Camera running touch ui on a Raspberry pi.

[Bigfellas]

Hey Paul. I have moved up to a official pi 7" screen. Mind you this problem existed on the small screen as well. Anyway I am not getting camera feed in the ui. getting a little ? icon on the screen. So I assume something is missing.
Thanks

Hi Matt,

Does the webcam work in the normal interface? And if so, could you perhaps add the .octoprint log in a pastebin??

yup working in the normal interface.
I think this is what you were after

Loads fine on a iPhone as well. So must be something missing with the Pi install.

Okay something weird is going on, I shortly had the same issue on my touchscreen but after saving the webcam settings with the touchscreen it resolved itself. (just open Settings > Webcam, press test and if you see in the preview the image feed, just save it and reboot the browser)

also it seems the feed stops working after a while (which is a kweb3 bug), if go to another page and you wait a few seconds and go back, then octoprint will reset the feed and it continues.

How do I press test I can't see anywhere to do that

[BillyBlaze]

Sorry I forgot I was on OctoPrint 1.3.0 (devel branch) where this test button is a new feature. Please take a look at the SnapStream plugin.

This plugin will fallback if mjpeg fails, and is exactly what you want.

After installing the plugin, save the SnapStream Settings with your config. Be sure you have unchecked Only use snapstream when mjpg-streamer fails. For some reason SnapStream doesn't work when MJPEG has failed in kweb3.

p.s. using SnapStream will lower your CPU usage, so I recommend using it with Touchscreens.

Unfortunately no go. I even switched to the Devel branch Still get a little ? even in the test screen.

Sorry I need more information; Did you install the SnapStream plugin? and what was the SnapStream settings you saved after installing it? Did you verify you have the correct settings?

(Verify settiigs: If you go to a desktop and open the browser with http://localhost:0000/cam.jpg, do you see a static image? (change the url to your settings)

Did you also try to uncheck Only use snapstream when mjpg-streamer fails?

There has to be something with your configuration since I am unable to reproduce the problem with SnapStream.

[Bigfellas]

Sorry Paul blundering my way through this. the only setting other than "Only use snapstream when mjpg-streamer fails" and I have tried this both ways, and frame rate is the path. I have left this at default /webcam/?action=snapshot
Do I need to change this.

http://192.168.1.250:8080/cam.jpg
When I put this in I get 404: Not Found!
Could not open file

[BillyBlaze]

I think the valid URL should be http://192.168.1.250:8080/?action=snapshot for your setup.

If that works in the browser then replace /webcam/?action=snapshot with http://192.168.1.250:8080/?action=snapshot and save it.

any luck yet?

[Bigfellas]

Sorry Paul. Been slammed at work no time for play. I'll have a crack tonight and get back to you

[BillyBlaze]

don't apologize :) I was just curious. Good luck!

[Bigfellas]

I just put a post on google+ octoprint not sure if you saw it about touch ui not fitting on a pi 7" screen. Not sure if you can shed any light on this.

[BillyBlaze]

thanks for the head up!

[Bigfellas]

Legend. That worked. Thanks again

[BillyBlaze]

Awesome!! Glad it works now. Your welcome!
