Where the OBS AMD Encoder Is Heading

If you’ve actively watched the OBS AMD Encoder repository, you most certainly noticed a huge gap in code submissions and sudden bursts of commits now. This all has a reason. Read more

The ‘Ashes of the Phoenix’ Update (AMF Encoder Plugin v2.0.0.0)

The plugin rises from the no-update-phase back to bring you an even better experience with High Efficiency Video Coding (HEVC) encoding, Variance Based Adaptive Quantitization (VBAQ), Pre-Pass support and Asynchronous Queue mode. Read more

The Encoder Rebirth Update (OBS Studio AMD Encoder Plugin v1.9.9.6)

Today I bring you one of the only public pre-releases that are going to happen, as everything else requires AMD to release a Driver which fixes the AMF runtime and firmware. But enough of me, here’s the update which is the true star of this post: Read more

The future of AMD Encoder: HEVC on RX 4xx, Pre-Pass, VBAQ and more!

AMD released version 1.4 of the AMF SDK back in January and I quickly got to work familiarizing myself with the changes and new sample tools. I did some rather extreme tests with the encoder, which resulted in me reporting 8 Issues to the AMF Issue Tracker – mostly GPU crashes or encoding failures. But with that out of the way, Patrons have now finally received the first official pre-release build, just as I promised back in December 2016. But what’s actually inside? Read more

What is the fastest way to get an Inverse Square Root? (Part 2)

Part 1: What is the fastest way to get an Inverse Square Root? Last time I covered what the fastest way was for single precision floating point, but what about double precision floating point numbers? Do they behave the same or will we run into even more issues on older hardware? Since the market starts looking towards 128-bit integers and quad precision floating point numbers, it’s time to also test this one while it’s still ‘fresh’. Read more

What is the fastest way to get an Inverse Square Root?

Everyone who works with a 2D or 3D development studio knows that eventually you will run into hardware that is too slow. Wether that hardware is what you currently have or what your target demographic has doesn‘t matter – you‘ll hit this limit, even if you try not to. That‘s why some clever people came up with different ways to make things faster. Seperating the FPU from the IPU, SSE and AVX and the famous Quake III floating point hack. But which one performs the fastest, and can we make that one even faster? Read more

Interview with K-Gaming about the AMD Encoder Plugin (German/Deutsch)

Hey guys, I recently answered questions from a Let’s Player that wanted to interview me about the Plugin and AMF. Fortunately for me it was in german, unfortunately for you it still is in german and I’m not going to translate it for you. Google Translate to the rescue. Here it is, in it’s full unedited german glory. Read more

Full Multi-GPU Support And More! (1.4.2.0 Update for the AMD Encoder Plugin)

Update: Two hotfixes have been released to fix additional issues. The download link has been updated. Today is the day that users with a multi-GPU system can finally use their other GPUs for streaming and recording – and today is also the day that OBS Studio no longer crashes on startup! This update adds full support for multi-GPU systems, fixes the crash on startup bug, fixes Filler Data being stuck on Enabled, makes Delta QP available even when not using Constant QP, fixes some UI things and more. I hope you’ll have as much fun using the plugin as I did creating it! On to the download: Read more

Version 1.4.1.5 of the AMD Encoder Plugin is out!

It’s another update for the same AMD Encoder fixing even more stuff. This time it’s mostly fixes for encoding quality and older drivers (APU stable drivers) and how presets behave. Read more

AMD Encoder Plugin 1.4.1.1 is out – Hotfix for a Hotfix for a Release!

Another hotfix is now available and it fixes issues with Constant QP and Automatic Profile Level selection. Some other fixes have also made it into this version. Read more
