How to Archive UniFi Protect Footage

Posted on by

Here are some links and notes on archiving a UniFi Protect’s footage.

Apparently, the .ubv files just need to be remuxed to .mp4 so they are easily playable. On the UniFi Protect appliances, they have a ubnt_ubvexport and ubnt_ubvinfo binary that can do the remux. You can copy the binary off and run it with QEMU on x86 hardware.

Helpful Links.

RSYNC

We can setup rsync to copy the raw footage off the Unifi Protect appliance. Once we have it locally, we can use the remux tool to convert the files to .mp4 so we can easily view them.

A cool thing about using rsync, is if our copy gets interrupted, we can just rerun the command and it will pick up where it left off without duplicating anything.

The following command is a mouthful. It searches for all the recorded video files for cameras with the MAC addresses specified. (MAC addresses can be found from the web interface), There are only a couple things to change or tweak for the command to work for you.

MAC1 should be the MAC address of camera 1 while MAC2 is the MAC address of the next camera we want to archive.
Change the dst_directory to the archive directory or drive.
And of course we need to change the IP address (10.0.0.1) to the UniFi Protect IP address.

ssh root@10.0.0.1 'find /srv/unifi-protect/video/ \( -name "MAC1*" -o -name "MAC2*" \) -printf %P\\0\\n' | rsync -a -v --exclude="*timelapse*" --files-from=- root@10.0.0.1:/src/unifi-protect/video/ dst_directory/

Here are the details for the commands.

  • -printf %P\\0\\n : Don’t print the full path, i.e. “/src/unifi-protect/video/”
  • -name “MAC1*” : Search for recording files that start with camera mac1 address.
  • -o -name “MAC2*” : Let’s us search for multiple “cameras” add more -o -name “mac3*” etc
  • rsync
  • -a : archive mode, copies date, permissions etc.
  • -v : verbose output. Not needed, but it is nice to see what it is copying.
  • –exclude=”*timelapse*” : Exclude timelapse files. Remove this if you want to archive them.
  • –files-from=- : Tells rsync to use the standard input for the list of files to download.
  • root@10.10.1.1:/src/unifi-protect/video/ : This is the source directory for where the video files are located
  • /archive/directory : The path where we are archiving the video footage.

Acquire ubnt_ubvinfo from UDM

Before we can use remux, we need to setup a local copy of ubnt_ubvinfo.

You should be able to use the following scp command to copy the ubnt_ubvinfo or ubnt_ubvexport binary from the UniFi Protect appliance.

scp root@10.0.0.1:/usr/share/unifi-protect/app/node_modules/.bin/ubnt_ubvexport ./

To install on Intel or AMD CPU’s, check out the following section on the unifi-protect-remux page.

https://github.com/petergeneric/unifi-protect-remux#quick-start-for-x86-linux

As a side note, it looks like you can download an old x86 version of ubnt_ubvinfo from archive.org. Use at your own discretion.

wget https://archive.org/download/ubnt_ubvinfo/ubnt_ubvinfo

Install unifi-protect-remux

Install ffmpeg

apt install -y ffmpeg

or 

dnf install -y ffmpeg

Now we can download and install remux.

wget https://github.com/petergeneric/unifi-protect-remux/releases/download/v3.0.6/remux-x86_64.tar.gz
tar zxf remux-x86_64.tar.gz
sudo mv remux /usr/bin/

Now we can remux the files.

remux --with-audio=true dst_directory/*.ubv

You will need to script a way to recursively loop through the directories, or just do it manually.

Peertube – Change Video Settings/Channels from Command Line

Posted on by

Since Peertube uses a Postgres database, we can log in and manually do bulk changes to videos. Things like updating a channel ID, Category, or Privacy can all be easily changed and it is easy to do bulk changes.

Access the Database

Login as the peertube user via ssh

ssh peertube@peertube-ip

Connect to postgres

psql peertube_prod

View videos

select * from video;

There is a bit much information, lets clean it up a bit

select name,category,id,"channelId" from video;

View all the channels. The id field is the channelId that is used in the above video table.

select id,name from "videoChannel";

Change video channel

update video set "channelId" = 100 where id = 123;

Replace 100 with the actual channelId and 123 with the id of the video. Can use the above commands to find that info.

Change Privacy Settings

The privacy settings are what determine if a video is Public, Private etc.

The following command can update the privacy setting for a video

update video set privacy = 3 where id = 101;

There are 4 privacy settings. Change 3 to one of the following.

1 = Public
2 = Unlisted
3 = Private
4 = Internal

Change 101 to the video id you want to change.

You can change the privacy settings for all videos in a channel with something like the following

update video set privacy = 4 where "channelId" = 100;

Unsupported DEB-based OS: /etc/os-release ID ‘kali’

Unsupported DEB-based OS: /etc/os-release ID ‘kali’. You can get the above error if you try to install AMD drivers on Kali Linux. Looks like by default they are looking for a system that is Ubuntu, LinuxMint or Debian.

You can resolve the issue by opening up the “amdgpu-pro-install” file and adding more OS’s that it can check for.

vi ./amdgpu-pro-install

Scroll down to line 147 where is says

ubuntu|linuxmint|debian)

and change it to 

ubuntu|linuxmint|debian|kali)

The code function should look like the following.

142 function os_release() {
143         if [[ -r  /etc/os-release ]]; then
144                 . /etc/os-release
145
146                 case "$ID" in
147                 ubuntu|linuxmint|debian|kali)
148                         :
149                         ;;
150                 *)
151                         echo "Unsupported DEB-based OS: `
152                                 `/etc/os-release ID '$ID'" | stderr
153                         exit 1
154                         ;;
155                 esac
156         else
157                 echo "Unsupported OS" | stderr
158                 exit 1
159         fi
160 }

Save a close the file and install the AMD drivers

./amdgpu-pro-install -y --opencl=legacy,rocm --headless

Videos flashing and resizing on Internet Explorer

Had a problem with a NVR not displaying cameras correctly in the web interface in Internet Explorer. The issue appears to be something wrong with how it is interacting with Windows scaling.

To resolve the issue you can set the scaling to 100%

or

If the monitor is a HDPI, set it to a 1920×1080 resolution with scaling at 100%.

Errors Renewing Lets Encrypt Certificate for UniFi-Video

Posted on by

Had an issue with the Lets Encrypt cert for a UniFi-Video server.  When renewing the cert and reimporting it into the UniFi-Video keystore, the certification was showing out of date.

Issue ended up being something with certbot.

When certbot runs it generates a new cert.pem, chain.pem, fullchain.pem and privkey.pem and puts them in the “/etc/letsencrypt/live/unifi.domain.com/” directory.

The privkey.pem and cert.pem are used to create the keys.p12 file which gets imported into the UniFi-Video keystore.

Apparently the .pem files in “/etc/letsencrypt/live/unifi.domain.com/” are symbolic links to files in “/etc/letsencrypt/archive/unifi.domain.com/”

Upon inspection of the archive directory, multiple cert.pem and privkey.pem files were found with the names cert1.pem, cert2.pem, cert3.pem etc.  Looking at the creation date of the file revealed the symbolic link was referring to an old “cert1.pem” file.

Work around was to stop the unifi-video service and reimport the cert using the latest .pem files in the archive directory.

echo ubiquiti | openssl pkcs12 -export -inkey /etc/letsencrypt/archive/unifi.yourdomain.com/privkey2.pem -in /etc/letsencrypt/archive/unifi.yourdomain.com/cert2.pem -name airvision -out /usr/lib/unifi-video/data/keys.p12 -password stdin
echo y | keytool -importkeystore -srckeystore /etc/letsencrypt/archive/unifi.yourdomain.com/keys.p12 -srcstoretype pkcs12 -destkeystore /usr/lib/unifi-video/data/keystore -storepass ubiquiti -srcstorepass ubiquiti

Remove the old ufv-truststore and start the service.

mv /usr/lib/unifi-video/data/ufv-truststore{,.old}
systemctl start unifi-video

Worked like a charm.
