I would use a USB webcam with Motion software, installed in Ubuntu on my Windows PC (WSL2 ) But when I started Motion as a service and i check on browser at the address [LOCALHOLST:port 8080 or 8081 ] it appears the Motion interface but never has been detected my webcam. Always It is showed a gray screen, for the MyCam1 option, with written at the top on the left "UNABLE TO OPEN VIDEO DEVICE". I tried many types of configurations in the camera1-dist.conf and motion.conf files, but unfortunately they still doesn't work Someone who could suggest me what type of configurations and in wich file, do I have to use to detected a USB webcam with Motion software ? Thank you in advance. Hi, many thanks your indications has been very useful! I have followed all the steps and I have attached the webcam to my Ubuntu distribution and now Ubuntu 'lsusb' comand gives the following output root@LAPTOP-5OFK2AK7:/home/daniele# lsusb Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 002: ID 3443:950a SHENZHEN AONI ELECTRONIC CO.,LTD NexiGo N950P 4K Webcam Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Unfortunately it still doesn't work..Motion still showes a grey screen and the UNABLE TO OPEN VIDEO DEVICE.. I think now the problem is in the camera1-dist.conf file. I'd like to set the webcam in localhost:8080 (port) or ( 8081 ) but i don't understand, it still doesn't work what and where I have to write in this camera1-dist.conf file # This config file was generated by motion 4.2.2 ########################################################### # Configuration options specific to camera 1 ############################################################ # User defined name for the camera. camera_name MyCam1 # Numeric identifier for the camera. camera_id 101 # The full URL of the network camera stream. netcam_url http://127.0.0.1:8080 # Image width in pixels. width 1280 # Image height in pixels. height 720 # Text to be overlayed in the lower left corner of images text_left CAMERA 1 # File name(without extension) for movies relative to target directory movie_filename CAM01_%t-%v-%Y%m%d%H%M%S

My local pc's address is 192.168.31.167. sudo ifconfig | grep inet inet 192.168.31.167 netmask 255.255.255.0 broadcast 192.168.31.255 Install motion and start it: sudo apt install motion sudo motion I can only get access video with 127.0.0.1:8081 in browser. Why 192.168.31.167:8081 can't play the video?

I've set up a webcam stream with Motion to use with Octoprint on my Raspberry Pi 4 (Raspbian 10). With my main webcam (Logitech C270) it works well as expected. I was testing to see if I could use a quite old webcam (Sunplus Flexcam 100 according to lsusb) I just found. I've managed to make it work, through VLC I can see the video feed just fine: (my red jumper and a green plastic object as color reference) However, when I start Motion, the image I see on the stream has the colours distorted (kind of looks like green and red are interchanged): I've tried changing the palette and hue config options, but nothing changes. I've also tried using the v4l2 prefix, as in v4l2:///dev/video0 in the videodevice config option, but it does not recognize it as valid. Any ideas as to what might be happening? Thanks in advance

I'm trying to set up the raspberry pi with my webcam as a motion detecting cctv that uploads the videos to google drive using [Jeremy Blythe's script](http://jeremyblythe.blogspot.co.uk/2012/06/motion-google-drive-uploader-and.html) I have motion working correctly and the python script runs when I test it from the terminal. However the script doesn't run when I add it to the on_movie_end option in motion.conf. The script I am using in the file is On_Movie_End /etc/motion/uploader.py /etc/motion/uploader.cfg %f I have also tried getting the on_movie_end to run a bash script that runs the python script and this doesn't work either. I am new to linux though so not entirely sure I have it correct. The script is: #!/bin/bash VIDEO=$1 /etc/motion/uploader.py /etc/motion/uploader.cfg VIDEO In motion.conf /etc/motion/uploaderscript.sh %f

I want to set up a daemon that starts recording video with sound when it detects noise or movement. There are tools that do that separately but can they be done at the same time? Can I set up motion in a way that when it detects motion it executes a script? Can I do the same with SOX?

I am writing an application which is based on Motion . Motion allows me to define a video4linux loopback device: # Output images to a video4linux loopback device # The value '-' means next available (default: not defined) ; video_pipe value # Output motion images to a video4linux loopback device # The value '-' means next available (default: not defined) ; motion_video_pipe value Motion already accesses the webcam to detect motion, now I would like to access images of the webcam, too. I think the loopback device is the right thing to do this. But what do I have to do exactly? Do I have to configure another(?) video4linux device and add it in the configuration? Motion offers documentation about this topic. But I find it hard to get starting, as I am still troubled with how the whole architecture is working.

The Motion documentation for lightswitch_percent is as follows: "Ignore sudden massive light intensity changes when the percentage of the picture area that changed intensity is greater than this value. The value defines the picture area in percent above which the lightswitch condition will trigger." The documentation for threshold_maximum is as follows: "This parameter specifies the maximum number of pixels that will trigger motion. When the number of changed pixels is above the maximum, it will not trigger an event. The result is that Motion will only trigger events when the number of pixels changes is above the threshold and less than the threshold_maximum. A value of zero disables threshold_maximum." The question is whether an intensity change for a pixel is just the same as a change to that pixel that would count against the threshold_maximum. For example, assume my configuration sets the threshold_maximum at 70,000, the lightswitch_percent to 70, and my image dimensions set such that my image contains 100,000 pixels. If a moving object changes 70,000 pixels in that image, doesn't that just barely trigger both the lightswitch_percent and the threshold_maximum? Perhaps they really are just the same thing for purposes of triggering the feature, but they just have different outcomes. When lightswitch_percent is triggered, the next few frames (default 5) are ignored for purposes of detecting motion. The result of a maximum_threshold being exceeded is only that the current frame is ignored for the purposes of detecting motion.

I am struggling to get Motion working properly. It is not currently writing files when it detects motion. I got my first Pi today. I have set it up, the camera works. I can take pictures and take video. These are being written fine. I have set up Motion and this appears to be working. I can stream the video via the IP address/web browser to a different machine. When creating movement in front of the camera this is detected - the log file motion.log updates and detects motion. However, stills are not being written. The target_dir folder is empty and a search of the file system doesn't find any new image files. How do I get the stills to be written when motion is detected? motion.conf is below.

How do I get two USB webcams to operate simultaneously on a Raspberry Pi 4 running openSUSE Leap 15.2? I ultimately want this to work with [Motion](https://motion-project.github.io) and seem to have eliminated that as I also fail with just ffplay from the command line. I have two [webcams](https://www.amazon.co.uk/gp/product/B015VE4KP0) plugged in to a [powered USB hub](https://www.amazon.co.uk/gp/product/B07KFDFT4D) . Both webcams work independently but not together. As a test, plugging the webcams directly in to the Pi or removing power from the hub gives me **device descriptor read/64 error -110** so the hub *is* providing power correctly. If I start the first cam as follows, I get a picture: # ffplay -f v4l2 /dev/video0 But when I then start the second, I don't get a picture (the first will continue to work); we just wait here and don't appear to timeout (can't say I've waited for more than a few minutes, though): # ffplay -loglevel debug -f v4l2 /dev/video2 ffplay version 3.4.8 Copyright (c) 2003-2020 the FFmpeg developers built with gcc 7 (SUSE Linux) configuration: --prefix=/usr --libdir=/usr/lib64 --shlibdir=/usr/lib64 --incdir=/usr/include/ffmpeg --extra-cflags='-fmessage-length=0 -grecord-gcc-switches -O2 -Wall -D_FORTIFY_SOURCE=2 -fstack-protector-strong -funwind-tables -fasynchronous-unwind-tables -fstack-clash-protection -g' --optflags='-fmessage-length=0 -grecord-gcc-switches -O2 -Wall -D_FORTIFY_SOURCE=2 -fstack-protector-strong -funwind-tables -fasynchronous-unwind-tables -fstack-clash-protection -g' --disable-htmlpages --enable-pic --disable-stripping --enable-shared --disable-static --enable-gpl --disable-openssl --enable-avresample --enable-libcdio --enable-gnutls --enable-ladspa --enable-libass --enable-libbluray --enable-libcelt --enable-libcdio --enable-libdc1394 --enable-libfreetype --enable-libgsm --enable-libmp3lame --enable-libopenjpeg --enable-libopus --enable-libpulse --enable-libspeex --enable-libtheora --enable-libtwolame --enable-libvidstab --enable-libvorbis --enable-libvpx --enable-libwebp --enable-libzimg --enable-libzvbi --enable-vaapi --enable-vdpau --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-version3 --enable-libx264 --enable-libx265 --enable-libxvid libavutil 55. 78.100 / 55. 78.100 libavcodec 57.107.100 / 57.107.100 libavformat 57. 83.100 / 57. 83.100 libavdevice 57. 10.100 / 57. 10.100 libavfilter 6.107.100 / 6.107.100 libavresample 3. 7. 0 / 3. 7. 0 libswscale 4. 8.100 / 4. 8.100 libswresample 2. 9.100 / 2. 9.100 libpostproc 54. 7.100 / 54. 7.100 Initialized opengl renderer.

This question is related to the [two](https://unix.stackexchange.com/questions/112087/broadcast-or-send-machine-readable-code-to-ssh-clients) [other](https://unix.stackexchange.com/questions/114080/run-linux-motion-app-as-user) questions I had earlier, about enabling Raspberry Pi to act as a motion sensor that will try to ssh into a more powerful server when it detects motion (the more power server will then do additional processing via a script). So here's what I did: - On the Raspberry Pi, I installed Linux motion app - I also used ssh-keygen on the Raspberry Pi and then using ssh-copy-id copies public keys to the more power server, so that the Raspberry Pi can ssh to the server without having to type in the password. - On the motion.conf file, there's a line for on_motion_detected event for when the motion is detected by Raspberry Pi, on that line, I have something like: >ssh user@more.powerful.server '/exec/some/script/here' - But the script on the more powerful server is never executed because the motion daemon is running as user 'motion', rather than the user (pi) that did the ssh-keygen that the remote server accepts. I know this because: - If I change the on_motion_detected command to: >on_motion_detected echo hello_world | wall this command gets executed and I see it on all the terminals that are ssh'd into the Raspberry Pi - Or, if instead of on the on_motion_detected line, I simply run ssh user@more.power.server '/exec/some/script/here' on the Raspberry Pi's command line (as user 'pi'), it also gets triggered by the server. So the question is, how do tell the Raspberry Pi's operating system to 'use' the key of the 'pi' user when the 'motion' user tries to ssh into the more powerful server, in that on_motion_detected event?

I want to use stream_tls option as this link which tells: > This option specifies whether to enable SSL/TLS for the stream port. > For some distributions the library that Motion uses may not have been > compiled with SSL/TLS support. In this situation Motion can not > support SSL/TLS connections. Whether SSL/TLS can be supported will be > reported in the log. In addition to selecting this option, a > webcontrol_cert and webcontrol_key file must also be specified. When I add stream_tls, webcontrol_tls, webcontrol_key and webcontrol_cert, it gives me these logs: [3626632:motion] [ALR] [ALL] conf_cmdparse: Unknown config option "stream_tls" [3626632:motion] [ALR] [ALL] conf_cmdparse: Unknown config option "webcontrol_tls" [3626632:motion] [ALR] [ALL] conf_cmdparse: Unknown config option "webcontrol_key" [3626632:motion] [ALR] [ALL] conf_cmdparse: Unknown config option "webcontrol_cert" I changed the configuration file /etc/motion/motion.conf and these lines: stream_tls on webcontrol_tls on webcontrol_key /etc/motion/motion.key webcontrol_cert /etc/motion/motion.crt In addition, I created /etc/motion/motion.key and /etc/motion/motion.crt by the following procedure: openssl genrsa -out /etc/motion/motion.key 4096 openssl req -new -key /etc/motion/motion.key -out /etc/motion/motion.crt My objective is to make motion stream web page secure (https). I don't know why it's happening. I'm sure the problem is not with .key and .crt file because if I just add stream_tls on, it gives the same error for this option. How can I solve this problem?

I am running motion on a Raspberry Pi with a surplus Microsoft Xbox camera. To the best of my knowlege I have set it up to only take an image every 30 minutes and to also create a daily timelapse with the images. However from the second I start it, motion is taking an image every second or so and saving it to my snapshoots folder. I dont want this to happen! Of course I want the live feed visable via the web UI but I only want an image to be saved every half hour as well as the daily timelapse. Here is what I belive are the relevant parts of my config files: My /etc/motion/motion.conf: The entire thing is here: https://pastebin.com/32cZNeGU # Maximum number of frames to be captured per second. # Valid range: 2-100.

I have a raspberry pi with motion installed. I have a mjpg at localhost:8081 and want to transfer it to an other webserver on the internet, so it's kind of a relay. I don't know where to find the mjpg on the file system for easy transfer, it's not in the configured folder. So, what's the best way to transfer my localhost:8081 to my webserver? It shows the live image of my webcam.

I am trying to get a hello-world stream working from a USB webcam to a browser over a local network using Motion. (On a Raspberry Pi). When I run service motion start on the RPi and go to http://192.168.0.xyz:8081 on my PC, the streaming works as expected. But when there is any movement, in Firefox it stops and says "Connection was reset". Refreshing sometimes makes it work, but sometimes gives a "Could not connect" message. In chrome the picture just freezes. I am not trying to use any motion-detection features for the moment, and have disabled all such options (that I have found). cat /tmp/motion.log is empty. Installation was as follows. (Everything was done as root to make things a bit simpler.) apt-get update apt-get install motion -y I then changed the following options in /etc/motion/motion.conf daemon off setup_mode off output_pictures off output_debug_pictures off target_dir /var/lib/motion stream_port 8081 stream_motion off stream_localhost off Then I run service motion start What am I doing wrong?

Right now my router implemented by OpenWRT. The router has motion and webcam for IP cam. But when I activated motion, the following error message appears: [CRT] [VID] mjpegtoyuv420p: Corrupt image ... continue [CRT] [VID] mjpegtoyuv420p: Corrupt image ... continue [CRT] [VID] mjpegtoyuv420p: Corrupt image ... continue [CRT] [VID] mjpegtoyuv420p: Corrupt image ... continue [CRT] [VID] mjpegtoyuv420p: Corrupt image ... continue [CRT] [VID] mjpegtoyuv420p: Corrupt image ... continue My webcam is a Logitech c270, and I believe it supports the MJPEG format. v4l2_palette 8 which it tells the router to use MJPEG for the webcam. I followed this website to solve the problem, but I can't find the file that suppose to be edited (file:common_video.c perhaps?). https://github.com/Mr-Dave/motion/issues/65

I am trying to configure motion (https://motion-project.github.io/) to record video files. No matter what value I set the framerate option the video files that are created all appear to have a framerate of between 1 and 2 FPS. I am running on a Raspberry Pi Zero. Is it possible that the frame rate is being throttled or limited by available memory or processor speed of raspi zero? Anyone have any insight into this issue? Here is my config file: https://pastebin.com/28teAEiJ

I'm experimenting motion on my desktop, My webcam: Logitech, Inc. Webcam C270 Output Images and video are ok but the image on built in server aren't. They are like blue and black - almost monochromatic but sometimes it get gray also. I've tried open with vlc and it's ok - I think it's related with the video compression before transmit it to the server.

I am running motion, and so far everything work nicely, I can access the stream on port 8081, without problem. Is there a way to show the stream of the same webcam on multiple port ? If yes, how ? I tried setting up this in motion.conf : stream_port 8081 stream_port 8082 But only the last port is reachable. How can both be reachable ?

I have a streaming video feed set up with the motion package. something like this: https://www.youtube.com/watch?v=jGkHSU-UPLU Works great. What I want to know, is who is connecting to my streaming media feed? It's supposed to just be my boyfriend. The light on my web camera is always on, even when he says he isn't viewing. I'm a little put off by this. Is there anyway to get more info about who (IP address) is viewing my stream? Does the camera stay on even when no one is connected?

I am trying to use motion software (but I could use just any other linux software) in order to "log" some manual work by snapshots. So imagine I want to make a stop-motion film with my LEGO(r) toys (just an example, but for better understanding), and my webcam should take one snapshot when my hands get out of the way. There are tons of docs in the Internet to achieve the opposite (record when move detected), but none this way: 1. wait until there is movement in the field of view 2. detect movement, so wait until movement stops 3. movement stops, so take an snapshot. Is this possible with motion, cheese, or other webcam software?
