RClone is the Rsync with the Cloud

August 7, 2018 Patrick Gilfeather

RClone is an extended feature set to rsync which provides a way to use cloud storage for file backups. To install it, refer to this link https://rclone.org/downloads/. In my example I run these commands to download and install RClone. wget https://downloads.rclone.org/v1.42/rclone-v1.42-linux-amd64.deb sudo dpkg –install rclone-v1.42-linux-amd64.deb Next is to configure RClone to use the cloud service. I ran this command to do that.

FFMpeg motion detection

August 6, 2018 Patrick Gilfeather

FFMpeg motion detection offers a way to create videos that are smaller and shorter becuase it only captures changed scenes. This post discussed the topic, https://superuser.com/questions/984841/ffmpeg-remove-parts-without-motion. Here is the command I used based off of this conversation. ffmpeg -i “http://viewr1:viewr1@192.168.6.184/mjpeg/stream.cgi?chn=0” -vf “select=gt(scene\,0.004),setpts=N/(25*TB)” IPCam4_Motion.mp4 The one thing I noticed was the timestamp in the video is being detected as a scene change, this introduces a higher noise floor. I found that my lowest scene value to be .004. This site, http://www.bogotobogo.com/FFMpeg/ffmpeg_thumbnails_select_scene_iframe.php…

DVR Video from Images Captured from IP Cameras

July 28, 2018 Patrick Gilfeather

Working with thousands of image files captured from IP Cameras can be problematic. I’ve experienced issues with Caja hanging when simply browsing the folders that contain the captured images. To work around this, I compile video with FFMpeg from the image stock into a separate folder. First I’ll create a file list using this command ls /home/local/Videos/Security/IPCam3_20180726*.jpg > /home/local/Scripts/IPCam3_20180726.txt The results will then need to be processed so FFMpeg can use the file as a reference.
