Help wanted setting up OBS Studio using hdmiin as "Video Capture Device" on rock-5b-plus

[chrishobcroft]

I am attempting to set up rock-5b-plus to use as a Desktop device, with OBS Studio for livestreaming.

My ultimate objective is that I wish to plug an HDMI signal (from a camera) into the HDMI input (`hdmiin`) and use this as a "Video Capture Device" for livestreaming from the camera.

 

Steps I have taken so far:

 

1. Written this to the microSD card: `Armbian_25.2.2_Rock-5b-plus_bookworm_vendor_6.1.99_cinnamon-backported-mesa_desktop.img.xz` downloaded via [this link](https://dl.armbian.com/rock-5b-plus/Bookworm_vendor_cinnamon-backported-mesa) available [here](https://www.armbian.com/rock-5b-plus/). I opted for this one as it appeared to include software to run MESA

2. Booted the rock-5b-plus from the microSD card and gone through first-time setup as well as running `sudo apt update && sudo apt upgrade -y`

3. Opened a Desktop UI on the computer and run `sudo apt install obs-studio -y`

4. On running obs-studio, observe the error message "Failed to initialise video. Your GPU may not be supported, or your graphics driver may need to be updated".

5. Set about trying to install `mali-g610-firmware` using this link for guidance:

6. Run the following to install amazingfate's signing keys:
```
wget -qO- https://build.opensuse.org/projects/home:amazingfate/signing_keys/download?kind=gpg | sudo gpg --dearmor -o /etc/apt/keyrings/obs-home-amazingfate.gpg
```

7. Append the following to `/etc/apt/sources.list` (although if mesa-bookwork-backport is already in the distro then I'm not sure why I need to do this)

```
deb [signed-by=/etc/apt/keyrings/obs-home-amazingfate.gpg] https://download.opensuse.org/repositories/home:/amazingfate:/mesa-bookworm-backport/Debian_12/ ./
```

 

8. Then update / upgrade / install

```

sudo apt update && sudo apt upgrade -y

sudo apt install mali-g610-firmware

```

But it tells me `E: Unable to locate package mali-g610-firmware`.

Here is some useful info:

 

```

chrishobcroft@rock-5b-plus:~$ cat /etc/apt/sources.list
deb http://deb.debian.org/debian bookworm main contrib non-free non-free-firmware
#deb-src http://deb.debian.org/debian bookworm main contrib non-free non-free-firmware

```

An update on this, I seem to have made some progress, but without completing the objective.

 

I added the following to /etc/apt/sources.list instead of the previous entry

 

deb [signed-by=/etc/apt/keyrings/obs-home-amazingfate.gpg] https://download.opensuse.org/repositories/home:/amazingfate:/panfork-mesa/Debian_12/ ./

 

and then ran:

 

sudo apt update && sudo apt upgrade -y

sudo apt install mali-g610-firmware

 

The install appeared to succeed, however OBS Studio still throws an error.
