VCEEnc VS AMF

https://github.com/rigaya/VCEEnc/releases has ability to use the latest amf with more options

First you will need the tools so you will need to go and download them in order. a. VCEEncC https://github.com/rigaya/VCEEnc/releases (chose the version that your windows support Win32 or x64)

Turns out the only place you can use the 10-bit HEVC encoder is this weird program called VCCEnc

as tested with the after my opinion the very best video encoder for AMD aka VCEEncC64 (you can find it on github https://github.com/rigaya/VCEEnc)

If anyone has older cards, can test it with VCEnc with a similar command of VCEncC64.exe -i -c avc --vbr 5000 --bframes 3 --ref 3 --b-pyramid --preset slow out.mp4

Some encoders have been having problems after 21.5.2 (including today's 21.7.1) https://github.com/rigaya/VCEEnc/issues/29

VCEEnc Changelog says HEVC 10bit and VP9 are supported.

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.
