currently I am trying to show my own UI and a third party virtual keyboard above the video which is displayed by omxplayer.
I am using a Raspberry Pi 3 (which is the reason for using omxplayer).
I am starting omxplayer from command line. I found the --layer n option but however it does not seem to change anything.
Did anyone ever come across something similar?
Thanks in advance

I got the following problem:
I need two cameras on my Raspberry Pi, so i bought a Waveshare IO-Base-A and a CM4 2GB. When trying to use two cameras with this setup, none of them work. Only one camera does work.
The official way on the Waveshare Wiki (https://www.waveshare.com/wiki/CM4-IO-BASE-A#CSI_DSI) doesn't work either, so i really don't know know what to do...
I do know that this isn't a problem that only occurs on my system, and it doesn't look like an Hardware-problem as well, since switching cameras etc didn't work for me as well. Editing the config.txt (on PiOS and Ubuntu Server) ends up with having 0 cameras that work. Only start_x=1 allows one camera to work.
Thanks for every answer
I'm trying to get to work a raspberry pi 0 W and a pervasive display eink screen together.
But, every time when the screen refresh, it reboots the pi 0. Software works great on a RPi3 but not on Rpi0w with Raspbian Lite.
Here is the soft : EpaperDisplay
Here is the screen : Screen
There is no log in /var/log/messages, neither in /var/log/syslog. Every time it reboots, it's erasing history, logs ...
If this was a software issue, you would probably see something in the logs (or you'd at least see a kernel panic message on the console in the HDMI output if you have a screen connected there).
If you have nothing in the HDMI screen when the pi crashes, I'd suspect that the display is using more power than your power supply can provide. Try with a PSU with a higher ampere rating.
If a better power supply does not help, it can be that the display sucks too much 3.3v from the raspberry pi than the zero can provide. In that case you should try feeding the display via a separate 3.3v regulator.
I have been experimenting with home home automation and want to turn my raspberry pi 3 into a hub not something my devices manually connect to e.g from the gpio pins. In many unsuccessful attempts I have tried OpenHab. I would like to mount a touchscreen with a GUI so I can e.g turn the lights on from this control panel instead of via phone or other hubs available like Google Home. If anyone knows how I might do this it will be much appreciated.
It seems like home-assistant with floorplan would work for this. It takes a little bit of configuring but well worth it.
I am new with this Pi device and just got an Pi 3 Model B. I would like to make a small project with it by turning it to become a dashboard to display some data which get from the server. To do this I have a server running on my laptop which will provide the data. Then I create an html page to draw the dashboard, I draw using highcharts tool. Finally I display the result on the Pi (connected with a monitor using HDMI cabel) by just using its web browser and access to the html page and then the result will be displayed on the monitor.
But what I realise at the end is that I just use the web browser of the Raspberry Pi to display the dashboard and this was not dealing much with the programming of the Raspberry Pi. Therefore I would like to ask that is there any other ways to program with the Pi so that it can connect with the server, get the result and then display the result in a chart as a dashboard. This sound better than my solution as using the Pi as a programming tool instead of displaying tool.
Thank you so much
I'm trying to run javafx8 application on raspberry pi model B. but keyboard input & mouse motions are seems bit slow. as a example I did it with one textfield on raspberry pi. when I typing to textfeild there is a delay. tableview also same. when I click on a raw. there is a delay between mouse click and selection. I read some blogs on internet that oraclejvm's performances are great on raspberry pi. Is it possible to run javafx controls without delay on raspberry pi? I done couple of optimization on raspberry pi. is it problem with javafx8 or raspberry pi performance?
As you are probably aware the pi does not like graphics very much. I have had the same problems (with swing rather than javafx). This can happen for multiple reasons. First check your OS version. I assume that your using raspbian which had a soft float version for a while. The armel version is way slower particularly in these areas. I would run apt-get upgrade and update first and if the problem persisted, download the latest version of the OS. You are correct that oracle jvm performance is quite good on the pi so the issue is likely to do with your particular setup.
