OBS Studio Hardware Encoding on AMD GPU?

Support Graphics & Display
1

Hi guys, I’m not sure how to get hardware encoding working in OBS. The only options that show up are the software x264 CPU encoding and something called “FFMPEG VAAPI H.264”. Is that second one the AMD hardware accelerated option? I’m not sure because the OBS auto-setup didn’t select that option. Also, the VAAPI option doesn’t appear under the “Simple” Output options, only the “Advanced” section.

Sorry if dumb question, I’m a total Linux/Manjaro noob :upside_down_face:

OBS version 28.1.2-2
AMD driver version 2018.05.04
Other system specs in profile

Does above refer to the proprietary drivers installed from AUR?

To have hardware encoding you need to build mesa with h2xx support.

You need a custom PKGBUILD e.g. GitHub - mesa-freeworld/mesa-freeworld: freeworld build of mesa for Manjaro unstable branch.

You may also need to adjust version if they are not up-to-date.

Thanks for the response! The driver I mentioned is the standard open-source one that popped up in the install menu. Here’s a the terminal output with the installed and available drivers:

mhwd -l -d                                                                                     ✔

Would any of these work? If not, where can I learn how to “build mesa”? I checked the Manjaro wiki and all I saw relating to Mesa was the last section on GPU drivers. Here’s that output:

glxinfo | grep OpenGL                                                                          ✔

It looks like Mesa is installed? Although I’ll admit I have very little idea what I’m looking at here; like I said I’m a total Linux noob.

EDIT: Thanks for the reminder on screenshots.
