Thanks for the reply. Just wondering why a package is provided that cannot work with the standard kernel/thinking there is another kernel option.

Why use a webbrowser for VNC? Seems like a security risk... is your viewer compatible with tigervnc (open source)? Run tiger would be my advice... I don't know of any google product I would trust with my privacy :p

We are wanting to use these at an intake area, those will perform different functions but I need to start looking into best security practices since it will be "public" facing.
All bets are off if there is physical access to the machine.

Re: Raspberry Pi 4 HEVC

Kodi 19 should use ffmpeg+v4l2, until then, you can use popcornmix's leia_pi4 branch which patches ffmpeg and kodi to use MMAL which can decode HEVC. LibreLE uses this branch as does Arch ARM.

You could create a simple script that takes the pic then sends to the webhost and then have a sys...

Re: [How can i run a bash script on boot with Pi 4B /4GB]

You could write systemd service to execute it for you once the network is up rather than a sleep line... I assume your distro is using systemd.

Never use a Linux native port on Windows for something like formatting a disk. What is wrong with using the provided mkfs.ext4 command? Just TRIPLE check you are applying it to the correct partition. If you haven't yet partitioned, use fdisk or gdisk and observe the same warning. To help: https://wi...

 Try LibreELEC, they have Kodi setup with hardware decoding via ffmpeg-mmal
Arch ARM also provides the popcornmix forks, both of which includes MMAL decoding for RPi4 or RPi3 and below if you prefer.

Re: Filezilla Server, Raspberry Pi 4

You want to run an FTP server on your Pi? There should be tons of options out there. What distro? Search the package repositories for FTP servers and pick one that appeals to you. If you must have the one you named, and if it isn't provided as a package, look into how to compile it.

 Just a quick one to say there is currently no soft throttle on the Pi4 for technical reasons.
Does that mean the RPi4 will not reduce clock speed or voltage based on temp? I read (perhaps incorrectly) that a temp of 80C causes a throttle in either CPU speed or voltage to CPU.

Re: How can I get the latest version of MariaDB?

Sounds like you just need to update your existing distro to get what you need. If you find that Raspbian does not provide the version you need, you can consider Arch ARM which usually ships packages following upstream releases with minimal delay. For example mariadb 10.4.7 is currently offered for a...
