Issues with Raspberry Pi 4

[thefpoff]

Issue trying to get this working on a Raspberry Pi 4 running:

Raspbian GNU/Linux 10 (buster).
openjdk version "10.0.2" 2018-07-17
OpenJDK Runtime Environment (build 10.0.2+13-Raspbian-2)
OpenJDK Server VM (build 10.0.2+13-Raspbian-2, mixed mode)

Here are the issues with start-armhf.sh

pi@workbenchraspberrypi:~/RivetCam $ bash start-armhf.sh
Error loading properties: setup.properties (No such file or directory)

And here is the --info

pi@workbenchraspberrypi:~/RivetCam $ ./start-x86-64.sh --info /dev/video0
OpenJDK Server VM warning: You have loaded library /home/pi/RivetCam/x86-64/libv4l4j.so which might have disabled stack guard. The VM will try to fix the stack guard now.
It's highly recommended that you fix the library with 'execstack -c ', or link it with '-z noexecstack'.

I tested this to see if I could get a video recorded from the camera and this did work:
ffmpeg -f v4l2 -s 320x240 -r 25 -i /dev/video0 test.avi

Thanks!

start-x86-64.sh will not work on RPi. start-armhf.sh is the right way there, as you have tried it first.
The error message shows: libvideo has skipped an unsupported image format: H.264
I have searched for the internet to find a solution for that, but had no luck. It might can happen, that v4l4j or v4l2 does not support H.264 at all?

As far as I know ffmpeg does not use v4l2, so it might work with that. Please try an application, that relys on v4l2.
