Hi! I am testing obs studio on arm linix on an rk3588 device. It works great, I have a demo here too.

Enjoy the videos and music you love, upload original content, and share it all with friends, family, and the world on YouTube.

I have the latest obs version compiled to arm64 but for some reason, it doesn't pick any arm64 vst plugin from the suggested locations (.vst at home/user/ , /usr/lib/vst, etc,etc).. and the log output doesn't mention anything st all about vst plugin failures... so, how to actually debug why it's not working??

I need very basic vst stuff..

Isn't VST a Windows thing? And Windows has never run on ARM except for a handful of niche things? (there was an attempt by Microsoft to make a version of Windows for the Raspberry Pi, but it was mostly seen as a joke and failed)

You might look for the equivalent functionality in LV2 or LADSPA, instead of VST...except that OBS doesn't do that for some reason.

Generally though, you want to keep the video and audio processing separate, so that each can be excellent at its own job, and then combine them at the last step. Practically, this means moving all of the audio processing out of OBS and into something else, that feeds OBS as an unchanged passthrough. That something else could be a physical mixer that feeds a dedicated sound card, or a DAW (Digital Audio Workstation) that feeds a loopback on the same machine. Either way, the raw audio sources go directly to the audio processor, not OBS, and OBS only sees the final result. Any audio plugins also go in the external audio processor, not OBS.

I'd recommend Ardour as a VERY capable DAW:
And if you can and haven't already, switch to Ubuntu Studio, which has both Ardour and OBS preinstalled, and a TON of plugins that already work:

Ubuntu Studio – A free and open operating system for creative people.

Add OBS's official PPA, according to the sticky thread in this forum, and the normal update process gets you the current version of OBS.
