I have been using OBS Studio on a RPi 5 and found it works very well. It can stream to a Pluto ( via a LAN setup ) at 1920*1080 HD at 2M SR.
It takes a bit of playing to get OBS to do all you want but the time spent is worth it in my opinion. You can easily control OBS from external keyboard keystrokes, so adapting an old vision mixer using a Pico is possible. It is also a possible repeater switcher/encoder when controlled from a Pico. Inputs from a networked Picotuner could double the number of frequencies a repeater could receive if it uses Rydes at the moment.
( working on that one! )

One thing I should mention about the way I use OBS Studio on a RPi 5.
I use Real VNC viewer on a Windows computer to control the RPi instead of a monitor and keyboard on the RPi. I also plug a USB keyboard into the RPi to test the keystroke control. So when setting up the RPi, turn VNC control ON if you want to make life easier!

Hi Martin, this is very interesting.
Is your 1920*1080 HD at 2M SR at H265?

I would like to have a go at trying this.

I am in the process of building a repeater controller/encoder for GB3EN based on a PC running OBS with a Ryde tuner(s) for input(s). Control of repeater would be from the valid video output pin on the Ryde via a joystick controller and an OBS plugin to control scene selection. Does the Pico tuner have this capability, if not how would you control automatic scene selection in OBS?

My first attempt used capture dongles for the Ryde (HDMI) and analogue tuners and using the Advanced Scene Switcher plugin in OBS. I could program it to see a change of video or a lack of change of video to switch between beacon pages and active tuners, it works quite well though not completely foolproof.

This seems a very promising compact repeater switcher solution, a Pico tuner, a RPi5 and a Pluto, very nice.

So not H265 BUT the video out could go to a H265 encoder (although there is a problem with the GB3NQ encoder at the moment. It is the cheap ENC1 one and has stopped doing a good HD output and the team are working on this.)
The Pico controller is being programmed by Alan G3XPY and takes the GPIO RX pins data to control a HDMI switch 8*1 and a video looper etc. Early days. I then found the RPi 5 could take the place of the switch, video looper and encoder (H264) and that is the next step maybe....
Instead of switching the HDMI switch or video looper, the OBS Studio can just have various scenes setup and switch between.
I think this is a very promising route to a repeater controller.

I just plugged in the Pluto to the RPi5 running OBS Studio and it works! I did load a bit into the rules dir from something I found on the Internet but I don't think I needed to.
Here are some screenshots:
