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? Continue Reading
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’.
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?
16.12.1 broke an experimental property that the plugin has been using, namely Full Range encoding. Due to an oversight on my part this caused more issues than it should have, which this update fixes. Hooray for quick updates! Continue Reading
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.
Today it’s time for another new version of the AMD Encoder plugin for OBS Studio. This one implements better multi-GPU support, changes some things internally and makes it way easier to spot configurations that overload the GPU by forcing the ‘Encoding overloaded’ message to appear.
Happy recording & streaming!
Update: Hotfix 1 has been released, fixing support for older drivers again.
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: Continue Reading
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. Continue Reading
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. Continue Reading
Turns out that some of the changes in 126.96.36.199 caused exactly what I hoped it wouldn’t cause: crashing on systems with Windows 7 and older. This has now been fixed with the help of Jim (maintainer of OBS Studio).
Additionally some crashes have been fixed that were caused by incorrect default parameters which have been changed to the correct value now. Frame Rate & Size should also now be properly applied again. Continue Reading
