Raspberry Pi 4 - OBS Studio

Raspberry Pi 4: Chronicling the Desktop Experience – OBS Studio – Week 20

Last Updated on August 20, 2020

In Operation

OBS Studio offers various sources. The first one I tested was Screen Capture (XSHM).

Don’t even think of recording at 1080p. You’ll get totally unusable frame rates. Here’s an example showing the terrible frames per second showing top in action.

As you can see, we’re getting around 4 frames per second. Tinkering with various options can raise the fps slightly, but nothing that fundamentally changes the position.

The wizard recommends that the resolution is scaled to 852×480. From my testing, this offered little tangible benefits when capturing with XSHM. Frames per second only improved to around 7-8 with the lower resolution. Again far too low for any serious usage.

Window Capture (Xcomposite)

Undeterred, I explored capturing windows, instead of the whole desktop. Here’s a video of Cantata in action. It’s captured at 30fps with a resolution of 852×480. RPI4 has enough grunt here. Although audio is a bit choppy on this particular video, I was able to clear up that issue.

I’m really enjoying this series. It seems that OBS Studio is out of RPI4’s capabilities. At least until the GPU is used.

I’d like to see coverage of productivity apps on the RPI4 – things like Evernote clients covered. Any plans?

Looks like obs is using software encoder although rpi4 can do fullhd HARDWARE encoding. Too bad.

You’re just repeating what Luke says in his Summary — “The RPI4 has a VideoCore VI GPU, but this isn’t being used by OBS Studio. Direct encoder support would offer much better performance.”
