OBS Studio Fails to Initialize

[ATATC]

In today's test, OBS Studio failed to run on Ubuntu 22.04 LTS for Raspberry Pi with the following error message:
"OBS failed to initialize video. Your GPU is not supported or your graphics drivers may need to be updated."

@fz20181223luogu @qmascarenhas I was not able to reproduce this issue on the virtual machine. I'm afraid that we have to schedule another test.

@ATATC we await your heads up for when we can do this based on your AP Exam schedule. @fz20181223luogu, while we wait for Terry, we can test Teams on the rpi with one of the cameras. This will also allow us to familiarize ourselves with the boot-up procedures for LEADS. Terry, if you can direct us to any updated docs on this, that would be great!

Running Teams is extremely simple just like it is on Windows. I'll send you the password of the Raspberry Pi on Edsby.

I'm trying to run an arm64 version of Ubuntu 22.04 LTS virtual machine on my Mac.

@ATATC Can you send me the password? I assume the rpi boots up on pwr connection.

[ATATC]

Sent. Pls check Edsby.

@fz20181223luogu Completed test today - MS-Teams runs fine and can switch between the 3 cameras on on the hub. We now need to figure out what the issue is with OBS on the rpi.

I believe you would probably paste that in #85.

According to https://forums.raspberrypi.com/viewtopic.php?t=337544, looks like exporting LIBGL_ALWAYS_SOFTWARE=true could fix this issue. However, this env var means that it always use no hardware acceleration. It could possibly lead to low performance.
