obs-gstreamer VS AMF

I'd recommend you to look for obs-vaapi and obs-gstreamer as plugins to utilize GPU encoding on OBS. On Flatpak they're available as OBS plugins you can install alongside the Flatpak version of OBS.

I wanted to start experimenting with GPU recording on my Ubuntu machine and saw this video from GloriousEggroll demonstrating VAAPI working better than ever using the obs-gstreamer plugin, which would now be the standalone obs-vaapi plugin. I'm running Ubuntu 22.10 and the latest stable version of OBS from the ppa. As instructed, I checked the VAAPI version on my system with vainfo, got this.

On Nvidia you'd use obs-gstreamer (it's the same but obs-vaapi has only the vaapi part, not the entire implementation) because vaapi isn't supported by Nvidia.

Plus, since my Crysis 3 gameplay I'm using obs-gstreamer which fixed the crappy ffmpeg performance while recording with hardware encoding.

Try obs-gstreamer plugin... I'll write the easy way tomorrow if you don't know how to compile and install it, but if you can read then it's fine

Use obs-gstreamer https://github.com/fzwoch/obs-gstreamer

The video description is a bit misleading. You need this OBS plugin in addition to installing gstreamer-vaapi.

VA-API is used to access fixed-function hardware on the GPU to encode/decode various media formats. New software can result in small quality improvements, like we saw in last year's AMF update, but it can only add new formats if said hardware was already on your chip. The RX 6600+ have hardware for AV1 decode only. Users of RDNA1 and older, as well as the 6400/6500 XT, will forever be completely SOL.

This has been a long running discussion over on github and has finally been addressed by both AMD and Meta. You need to run at least 23.2.2 and Oculus V53 Desktop app (currently only in Public Test Channel, but you can enroll in the app).

By the way you can check the progress of this bug performance here: https://github.com/GPUOpen-LibrariesAndSDKs/AMF/issues/384

If you had issues on the latest 23.4.1 driver, I recommend going all the way back to 22.2.3 as that's the best driver for Oculus (doesn't enforce bitrate limits, more info https://github.com/GPUOpen-LibrariesAndSDKs/AMF/issues/364).

AMD finally acknowledged and fixed the 100Mbps encoder cap bug in 23.2.2. Now, it's up to Meta to update the Oculus desktop app. For those familiar, there have been multiple threads on the internet plaguing the encoder quality and stability for all 3 VR software (AirLink, VD, ALVR), but as of now, it is in the best state.

Meta/Quest VR headsets had even more issues since they depended on hardware video encoding, and for the longest time many had to stick to a certain version for the encoders to even work. AMD's HEVC encoder is still broken on Oculus Link and there was an artificial bitrate cap added as they try to fix the driver.
