Unable to open video device

jolabpi commented 8 years ago

Hi, I haven no success in getting a videostream in my browser although with VLC on Raspbian I can get a stream from my IP camera as well as from webcams(with v4l2). Using motioeyes I can add the cameras (using same URL as with VLC), the cameras are added to the viewer but the screen remains grey "Unable to open video device). I also tried out the emotioneyesOS on my raspberri PI2. Same behaviour. I'm at a loss how to proceed further. Do you have some tips ? Thnx Johan

i have the same problem. by using http://sourceforge.net/projects/onvifdm i get the url of my ip-cam. with motioneyeos i get the rstp stream, under raspbian / motioneye the same error.

do you use this instruction ? https://github.com/ccrisan/motioneye/wiki/Install-On-Raspbian

do you know how i can check using mrdave ?

ccrisan commented 8 years ago

Run motion -h and let us know the version it prints out.

Dobi29 commented 8 years ago

what are the steps to install motion / mrdave on a new raspbian installation ? i try it this evening...

-sudo apt-get install motion and then note 2: A prebuilt version of Mr Dave's motion for Raspbian can be downloaded from here. Just download it and copy it to /usr/local/bin/motion.

that's all to run mrdave ?

ccrisan commented 8 years ago

Yes!

jolabpi commented 8 years ago

using ssh from my android phone this is what is returned by MotionEyesOS on running the motion-h command:

using motion binary /usr/bin/motion-mrdave

jolabpi commented 8 years ago

for motioneye on raspbian I will redo a full clean install but already the first time I followed your instructions to install motion-mrdave without result. Maybe I overlooked something ?

Dobi29 commented 8 years ago

a few days ago a made a installation following your instructions. by using motion -h i got "motion 3.2.12+git20140228". that's why i ask for the steps to install of mrdave...

With MotionEyesOS connecting to a networkstream rtsp:// I got video in the webbrowser. I had to remove the requirement for rtsp authentification in my camera server. Found this by looking at the motion log. It seems the url which MotioEyesOS passes on does not contain the user:password strings as entered in the user password textboxes. Now we only have to resolve the use of using a webcam.

Dobi29 commented 8 years ago

these are my steps for running mrdave...

-sudo apt-get update -sudo apt-get upgrade -sudo wget https://github.com/ccrisan/motioneye/wiki/precompiled/ffmpeg_2.8.3.git325b593-1_armhf.deb -sudo dpkg -i ffmpeg_2.8.3.git325b593-1_armhf.deb -sudo apt-get install motion -sudo cp /home/pi/downloads/motion-mrdave-raspbian /usr/local/bin/motion -motion -h

unbenannt7

where is mrdave ?

ccrisan commented 8 years ago

You'll probably need to make it executable as well: chmod +x /usr/local/bin/motion.

ccrisan commented 8 years ago

That's what i'm talking about :)

Dobi29 commented 8 years ago

...that's it.. Perfect. Now it works. Thanks for your help.

ccrisan commented 8 years ago

I'm glad it could help. I'll update the wiki instructions.

jolabpi commented 8 years ago

My problem with webcams was due to incompatible cams. Just tried it out now with a logitech c270, works OK. Great program.

Salut, incerc sa implementez o camera sonoff gk-200mp2-b pe un sistem HomeAssistant care ruleaza pe un VirtualBox si nu reusesc sa primesc semnal video. Apare mesajul mesajul "Unable to open video device" sau o iconita cu o camera taiata. Nelamurirea mea este, in primul rand daca MotionEye functioneaza pe Virtual Box si daca este posibil ca problema sa fie codecul ffmpeg pe care cunostintele mele de programare ma incurca in a-l instala pe HomeAssistent-ul instalat pe Oracle VM Linux (64). Multumesc!

starbasessd commented 2 years ago

Yes, motionEye works on VirtualBox, it's how I recreate user issues on PC hardware or 'normal linuxes. Have you tried: add camera URL rtsp://ip_address/live/ch00_0 with username and password added to the correct boxes? There is one listing for Sonoff on iSpy (best resource for finding camera URLs IMO) There are many known issues with HomeAssistant and motionEye. You don't say what your base OS is for the VM, You could test a clean Ubuntu 21.04, and install motionEye (without HomeAssistant) using these instructions: https://github.com/ccrisan/motioneye/wiki/%28Install-On-Ubuntu-%2820.04-or-Newer%29 If you can get it to work, then you can try adding HomeAssistant to the mix. This issue is from 5 years ago. Please open a new issue for further help.
